Objectives To examine the association between cigarette price increase and youth smoking initiation in Bosnia and Herzegovina (B&H), and to assess additional factors—including parental smoking, peer influence, pocket money, anti-tobacco media exposure and smoking in school environments—that potentially affect smoking initiation among adolescents. Design A pseudopanel study using WHO Global Youth Tobacco Survey (GYTS) data from two compatible surveys conducted in 2018 (Republic of Srpska) and 2019 (Federation of B&H). A split-population duration model was employed to estimate the hazard of youth smoking initiation. Setting Primary and secondary schools across two entities in B&H, covering both urban and rural areas. Participants A total of 9702 students aged 13–15 years completed the surveys. Inclusion criteria involved being enrolled in grades 7–9 of primary school or the first year of secondary school. No additional exclusion criteria were applied beyond incomplete or invalid survey responses. Interventions None. Primary outcome measure Self-reported smoking initiation, defined as having tried or experimented with cigarette smoking, even one or two puffs. Results A 10% increase in cigarette prices was associated with a 4.9% reduction in the probability of youth smoking initiation (price elasticity of −0.491, p<0.001). Exposure to antitobacco media messages was linked to a lower likelihood of smoking initiation. Conversely, parental smoking, peer influence, observing smoking within school premises and having greater disposable pocket money all showed significant positive associations with youth smoking initiation. Conclusions Raising cigarette prices constitutes an effective measure to discourage smoking initiation among youth in B&H, operating both directly and indirectly through reductions in parental and peer smoking. Nonetheless, non-price factors play a substantial role, highlighting the complexity of adolescent smoking behaviour and the necessity for a comprehensive, multifaceted tobacco control strategy. Trial registration Not applicable (observational study).

Abstract Green innovations are applied in various industries to promote corporate sustainability by adopting sustainable development practices. However, very little is known about how the knowledge management process influences corporate green innovation. To contribute to the development of this issue, this study explores the relationships between knowledge management, corporate sustainable development and green innovation. Data was collected from 210 respondents from private companies in a developing country context and analyzed using the structural equation modeling technique. The findings provide several conclusions. First, the components of knowledge management (application, acquisition and sharing of knowledge) significantly improve the dimensions of corporate sustainable development (environmental, economic and social dimensions). Second, sustainable environmental practices have no effect on the adoption and application of green innovations by companies, however, sustainable social practices have a positive effect on green innovations. The results of this research also show that investing in knowledge management is of great importance for achieving sustainable development, as well as investing in the application of sustainable social practices.

Abstract Although a significant number of studies analyzing the impact of transformational leadership on job performance has been recognized, there is a lack of research considering this construct in the context of managerial performance, and along with interpersonal characteristics. To fill this gap, this paper has been built on Mintzberg’s (1973) premise according to which interpersonal skills play an important role in achieving not only managerial performance but also their leadership styles. In other words, it has been argued that transformational leadership behaves as a mediator in the relationship between social skills and managerial performance. Given the main findings, the paper contributes to practical thinking by indicating the importance of including social skills training focused on building social flexibility and presentation skills, so that managers could have a greater positive impact on managerial performance. As a consequence, it is well known that their better performance increases overall organizational success, which is a valuable lesson for a developing country setting in which this research has been conducted. Contributions to theory and practice are offered after which direction for further research follows.

Neuroinvasive arboviruses such as tick-borne encephalitis virus (TBEV), West Nile virus (WNV), Usutu virus (USUV), and Toscana virus (TOSV) have (re-)emerged with increasing incidence and geographic range. We analyzed the epidemiology of arboviral infections in Croatia during the 2024 transmission season. A total of 154 patients with neuroinvasive diseases (NID), 1596 horses, 69 dead birds, and 7726 mosquitoes were tested. Viral RNA was detected using RT-qPCR. IgM/IgG-specific antibodies were detected using commercial ELISA or IFA, with confirmation of cross-reactive samples by virus neutralization test. RT-qPCR-positive samples were Sanger sequenced. Arboviral etiology was confirmed in 33/21.42% of patients with NID. WNV was most frequently detected (17/11.03%), followed by TBEV (10/6.49%), USUV (5/3.24%), and TOSV (1/0.64%). WNV infections were reported in regions previously known as endemic, while in one continental county, WNV was recorded for the first time. USUV infections re-emerged after a six-year absence. In addition to human cases, acute WNV infections were recorded in 11/395 (2.78%) of horses and two dead crows. WNV IgG seropositivity was detected in 276/1168 (23.63%) and TBEV IgG seropositivity in 68/428 (15.88%) horses. None of the tested mosquito pools were positive for WNV and USUV RNA. Phylogenetic analysis showed the circulation of WNV lineage 2 and Usutu Europe 2 lineage. Climate conditions in 2024 in Croatia were classified as extremely warm, which could, at least in part, impact the quite intense arboviral season. The spreading of flaviviruses in Croatia highlights the need for continuous surveillance in humans, animals, and vectors (“One Health”).

Beetroot (Beta vulgaris L.) is a plant grown for its roots, which are used to obtain sugar, feed animals, and for human use. Beetroot skin, a by-product of food processing, is a significant source of bioactive compounds, including dietary fiber and antioxidants. The primary objective of this work was to utilize beetroot skin powder to produce value-added nougat. Analytical methods, like antioxidant activity tests, proximate analysis, and sensory assessments, are used to determine the impact of beetroot skin powder on the final product. The beetroot skin powder extract had a remarkable content of phytochemicals and antioxidant activity. The inhibitory effect of the extract was tested on enzymes linked to metabolic syndrome, oxidative stress, and inflammation. The beetroot skin powder extract inhibited α-glucosidase, α-amylase, lipase, and lipoxygenase enzymes. The characterization of value-added nougat illustrates the multifunctionality of beetroot peel powder within its composition, serving as a significant source of natural compounds with antioxidant, coloring, and flavoring properties. This enhances sensory attributes, including color, aroma, and texture, augmenting product diversity and consumer appeal. This is evidenced by the increase in the total content of betalains (3.77 ± 0.09 mg/g DW.) and polyphenols (69.48 ± 2.88 mg GAE/100 g DW.), which lead to high antioxidant activity (73.89 ± 3.65 mM Trolox/100 g DW.) for the nougat sample with 6% added beetroot powder. Thus, beetroot skin powder replaced chemically synthesized additives with antioxidants and natural pigments, improving life quality and implicitly capitalizing on beetroot processing by-products, supporting circular economy principles at the global level.

SUMMARY The aim of this study was to examine the effect of the lipid parameter non-high-density lipoprotein cholesterol (non-HDL-C) on the occurrence of major cardiovascular event (MACE) in patients after first-time ST-elevation myocardial infarction (STEMI) treated with primary percutaneous intervention (pPCI) and implantation of drug-eluting stent (DES). Seventy-eight patients (54 male and 24 female, median age 58.62±11.14 years) with the diagnosis of first-time STEMI who were treated with pPCI with DES implantation in the period from January 2018 until January 2020 were included in the study. Patients were followed for two years of the intervention for the occurrence of MACE and its association with baseline non-HDL-C, as well as total cholesterol, LDL-C, HDL-C and triglycerides. During 2-year follow-up, 20 (25.6%) patients had MACE. There was no significant difference in baseline parameters such as age, hypertension, presence of diabetes mellitus, and post-interventional use of statin therapy between patients with and without MACE. The levels of baseline lipid parameters were significantly higher in patients who experienced MACE, as follows: total cholesterol (p=0.009), LDL-C (p=0.028) and non-HDL-C (p=0.007). Pearson χ2-test showed that both non-HDL-C and LDL-C were significant predictors of MACE occurrence during 2-year follow-up, but non-HDL-C had a more significant correlation than LDL-C (p=0.007 vs. p=0.028). Our initial report shows that baseline non-HDL-C was a more significant predictor of the occurrence of MACE after first-time STEMI than LDL-C, which reflects the importance of the residual risk of MACE occurrence while enabling identification and close monitoring of high-risk patients.

The paper examines the impact of budgetary accounting organization on the perception of corruption in the public sector, focusing on three key independent variables: the financial reporting framework, the accounting basis, and the level of independence of state auditing. The Corruption Perceptions Index (CPI), which measures the perceived level of corruption in the public sector, is used as an indicator of the dependent variable. The study includes data from 89 countries. For statistical analysis, categorical independent variables were encoded using the one-hot encoding method. Statistical tests were applied to assess the correlation between the independent variables and the CPI. The results show variations in correlation depending on the combination of financial reporting factors, the regulatory framework, and the quality of state auditing. The obtained results of multiple linear regression indicate that the model has a statistically significant impact on the CPI (p = 0.0217) and explains 21% of its variability. Keywords: public sector accounting, budgetary accounting organization, perception of corruption, public financial management reform.

Intracranial epidermoid cysts are rare, benign lesions accounting for 1% of intracranial tumors.1 They may arise from misplaced squamous epithelium during neural tube closure, and are found in the paramedian position, cerebellopontine angle, or parasellar region with other locations considered rare.2-4 The far lateral approach and its extensions enables access and visualization of ventral and ventrolateral lesions at the craniocervical junction without retraction.5-15 A 32-year-old female presented with gait instability, visual disturbances, and severe headaches. MRI demonstrated a solid, non-contrast enhancing T1 hypointense and T2 hyperintense lesion in the right cerebellomedullary cistern with mass effect on cerebellum and brainstem, consistent with radiological findings of epidermoid cysts. The patient underwent far lateral suboccipital craniotomy with partial posterior medial condylectomy and C-1 hemilaminectomy while prone, which enabled unobstructed ventral view. A 4 hand (ie, 2 surgeon) microsurgical technique in tumor resection enabled dynamic, gentle tissue retraction and safe tumor resection. Apart from transient swallowing problems that resolved 2 weeks post-operation, the patient's postoperative course was uneventful. Follow-up MRI revealed gross total removal. This video demonstrates the steps, anatomy, and technical nuances for vascular and neural preservation during removal of epidermoid cysts in the cerebellomedullary cistern. To the best of our knowledge, this is the first operative video showing the resection of a pure cerebellomedullary cistern epidermoid cyst. The utility of fat graft dural closure enhancement decreased the risk of CSF leak. The patient provided consent. Institutional review board approval was not required for individual cases and thus was not sought.

Introduction The implementation of nationwide viral hepatitis C elimination programs is challenging in Central and Eastern European countries (CEEC). It is reasonable to start by targeting specific populations, such as people living with HIV (PLWH), who are at higher risk of acquiring HCV or developing HCV-related complications. Methods Euroguidelines in Central and Eastern Europe Network Group consists of experts in the field of infectious diseases from 26 countries in the region. Between April 26th and June 23rd 2023, the group performed an on-line survey consisting of 32 questions. The questionnaire assessed the status of HCV micro-elimination in 2022. Results Twelve HIV centers from 11 countries responded: Albania, Bosnia and Herzegovina, Croatia, Czech Republic, Estonia, Greece, Hungary, Macedonia, Moldova, Serbia and Ukraine. All centers screen for HCV antibody all PLWH at entry into care. The seroprevalence of anti-HCV was <5% in 5 centers (Albania, Croatia, Serbia, North Macedonia and Hungary), 30.2% in Estonia and 29% in Ukraine, Greece and Moldova had high seroprevalence as well, 15.3% and 15.6% respectively. The prevalence of HCV viremia in antibody-positive PLWH was very high in Greece (85%), while in most other treatment centers it ranged from 4.2% to 38.2%. There is also a screening policy of annual HCV-testing of HCV-antibody negative persons in all centers by either testing all PLWH or those considered at risk. Direct-acting antiviral agents (DAA) were not available in one country (Albania). Among PLWH who entered care in 2022, nine out of 12 ECEE centers reported cases of HCV/HIV coinfection, with five centers indicating that at least 50% of these individuals were HCV-viremic. Conclusions HCV screening in PLWH followed by access to DAA treatments were available in all but one center. Microelimination of HCV in PLWH in the majority of surveyed HIV treatment centers in CEEC has not been achieved and efforts to reach this goal need to be strengthened.

The application of X-ray methods (using conventional sources or synchrotron radiation) for investigating degradation phenomena in paintings has significantly increased in the last two decades. This rise is due to their ability to provide spatially resolved elemental, molecular, and structural information from the macroscopic to the nanoscopic levels. This review will focus on the application of latest-generation X-ray techniques, including X-ray fluorescence (XRF), X-ray absorption spectroscopy (XAS), and X-ray diffraction (XRD), to study the alteration processes of pigments in paintings. The first part outlines the fundamentals of XRF, XAS, and XRD techniques and then describes the corresponding instrumental set-ups used for non-invasive macro-scale mapping of paintings and synchrotron radiation-based X-ray analysis of paint micro-samples. Subsequent sections will cover advancements in X-ray data analysis software, workflow management systems, Open Science and FAIR data initiatives, alongside practical aspects of sample preparation and issues concerning X-ray-induced damage to paints. The final section will review degradation phenomena resulting from chemical changes of selected classes of pigments. This will involve describing key findings obtained from paintings, related micro-samples, and artificially aged paint mock-ups. The outcomes discussed in this review highlight their crucial role in developing effective monitoring and preventive conservation strategies for artworks highly susceptible to degradation within heritage sites and museums.

Abstract In the context of increasing challenges in the fight against financial crime, this paper analyzes the significance of forensic accounting in identifying suspicious transactions within the financial sector, with the aim of strengthening efforts to combat money laundering in Bosnia and Herzegovina (BiH). Money laundering is a complex form of financial crime that can be committed by individuals or large organizations. This form of financial crime is known from individuals to large organizations, and over time, different methodologies for carrying it out have developed. The detection and prevention of money laundering and the financing of terrorist activities in BiH are regulated by the Law on the Prevention of Money Laundering and Financing of Terrorist Activities (“Official Gazette of BiH,” No. 13/24), as well as the Rulebook on the Implementation of the Law on the Prevention of Money Laundering and Financing of Terrorist Activities (“Official Gazette of BiH,” No. 41/15 and 24/23). This paper aims to identify weaknesses in the financial and regulatory oversight systems in BiH. It also explores the level of understanding of forensic accounting techniques and money laundering mechanisms within organizations in the country, and assesses their impact on the overall effectiveness of anti-money laundering efforts.

Abstract The Constitution of Bosnia and Herzegovina is primarily notable for being an annex to the Dayton Peace Treaty that ended the 1992–1995 war. A significant aspect of this constitutional framework is its emphasis on the three main ethnic groups – Bosniaks, Croats, and Serbs – designated as constituent peoples, which play a central role in the state’s governance and institutions. The recent decision of the European Court of Human Rights (ECtHR) in the case of Savickis and Others v. Latvia has indirectly highlighted the (in)compatibility of certain constitutional solutions in Bosnia and Herzegovina with the principle of non-discrimination of the European Convention on Human Rights. In this article, the authors explain how the Constitutional Court of Bosnia and Herzegovina did not seek to implement the rulings issued by the ECtHR, but rather interpreted the constitutional identity of the country as being based precisely on the central role given to the constituent peoples. In so doing, the Constitutional Court, now also supported by the case Savickis and Others v. Latvia, created the prospect of abuse of constitutionalism in Bosnia and Herzegovina.

This study aimed to compare anthropometric characteristics, body composition, and physical performance parameters between more and less experienced wrestlers to determine the influence of competitive experience on key performance indicators. A total of 47 male wrestlers were divided into two groups based on their competitive experience: more experienced (n=22, >6 years) and less experienced (n=25, <6 years). Anthropometric measurements included body mass, height, body mass index (BMI), and body fat percentage (BF%). Performance assessments consisted of the countermovement jump (CMJ), handgrip strength (HGS), and the Specific Wrestling Fitness Test (SWFT). Group differences were analyzed using t-tests for independent samples, and discriminant canonical analysis. More experienced wrestlers had significantly lower body fat percentage (p=0.04) and better performance in the SWFT repetitions test (p=0.001) compared to their less experienced counterparts. They also exhibited a lower heart rate response during the SWFT (p=0.01), indicating better recovery capacity. Also, competing experience was correlated to SWFT repetitions (R=0.51) and SWFT index (R=-0.45). Wrestling experience appears to be associated with wrestling-specific performance. However, the experience did not significantly influence absolute strength or explosive power. These findings suggest that training programs for less experienced wrestlers should emphasize wrestling-specific performance development to improve performance.
