Abstract Introduction. Sports are frequently investigated in relation to alcohol consumption habits in adolescence, but few studies have reported various competitive- and recreational-sport factors as correlates of harmful alcohol consumption in youth. This cross-sectional study aimed to identify possible associations that may exist between sports factors and harmful drinking in adolescents, emphasizing the specific influence of participation in competitive and recreational sports. Material and Methods. The participants were 650 adolescents from Bosnia and Herzegovina (16-17 years of age, 313 females) who were tested for sociodemographic factors, competitive-sport factors, recreational-sport factors, physical activity levels (PALs), and outcome-alcohol drinking (obtained by Alcohol Use Disorders Identification Test – AUDIT). For the purpose of statistical analyses, the obtained AUDIT score was dichotomized (non-harmful vs. harmful drinking). Results. Harmful drinking was more common in males than in females (χ2 = 47.01, p < 0.001), and those adolescents who reported better competitive success in sports (χ2 = 41.81, p < 0.001). The PAL was greater in those males who did not report harmful drinking (t-test = 2.45, p < 0.05), with no significant difference in females or in the total sample. Logistic regressions were performed with sex as a confounding factor and revealed that competitive success in sports was significantly correlated with harmful drinking (OR = 1.32, 95% CI: 1.02-1.66, p < 0.05). Conclusions. This study highlighted the specific association between competitive sports success and harmful drinking in adolescents, indicating the need for a more detailed analysis of the background of the established association. Further analyses on the potential association between PAL and substance misuse in youth are warranted.

Abstract The paper focuses on analyzing key factors influencing the effectiveness of internal audit in the public sector of Bosnia and Herzegovina (BiH). Through multiple regression analysis (Ordinary Least Squares-OLS), the impact of five independent variables (competence of internal auditors, size of internal audit department, relationship between internal and external auditors, management support for internal audit, and independence of internal auditors), two control variables (organization’s sector and total number of employees in the organization), on the dependent variable (effectiveness of internal audit) was measured. Research results indicate that a significant portion (.2 = 45.00%, Adj .2 = 40.90%) of the variability in the effectiveness of internal audit can be explained by the variability of the five independent variables in the model. The largest positive impact on the effectiveness of internal audit is attributed to the size of the internal audit department and the independence of internal auditors. Conversely, management support for internal audit had the least impact, which contradicts our predictions and the results of previous research. The limited impact of management support on the effectiveness of internal audit in the public sector of BiH may stem from a lack of understanding regarding the role and importance of internal audit, as well as from perceiving it as merely a formal legal requirement without substantial value.

Abstract Current literature on the privacy paradox in personalised advertising lacks insight into how consumers’ knowledge of the data types used shapes their responses to these ads. Building on privacy calculus theory, theory of reasoned action, and signalling theory, this research explores how consumers’ knowledge of data types in personalised advertising influences their reactions. Multigroup path analysis examines differences in established relationships based on consumers’ data knowledge. The moderating effect of this knowledge in the relationship between perceived invasiveness and purchase intentions is also tested. Findings from a sample of millennials indicate that privacy concerns increase perceived invasiveness. However, multigroup and moderation analyses reveal that perceived invasiveness’ impact on purchase intentions varies with consumers’ data knowledge. Specifically, in the search history group, perceived intrusiveness negatively affects purchase intentions. These results underscore the situation-specific nature of the privacy calculus and assist advertisers in understanding consumer behaviour in response to personalised ads.

SUMMARY The aim of this research was to examine the rheological parameters of carotid arteries and the frequency of abnormal values in patients with metabolic syndrome (MetS) with and without diabetes mellitus (DM). The sample consisted of 90 subjects and was divided into two equal groups. The first group consisted of patients with MetS but without DM, while the second group had both MetS and DM. We used the values of the peak systolic velocity (PSV) as a reference for pathology. The results showed pathological values of PSV in the right internal carotid artery (ICA) in twelve patients in the MetS + DM group. The study found that the incidence of pathological rheological parameters was higher in subjects with MetS + DM as compared to those with only MetS. Subjects with MetS + DM had higher values of maximum acceleration during systole in various carotid arteries. A subject with MetS + DM also showed total flow obstruction in the left and internal carotid artery (ICA) and a severe narrowing of the right ICA, indicating the presence of carotid artery disease. The study also found that nearly two-thirds of subjects with MetS + DM had pathological values of PSV in the right ICA and slightly fewer in the left ICA. Research on French populations has shown similar results. Eleven patients had pathological values in the left ICA. The frequency of the carotid rheological parameters’ abnormalities was significantly higher in the MetS with DM patient group. The frequency of abnormalities in the rheological parameters of carotid circulation was significantly higher in patients with MetS and DM (as compared to non-diabetic patients). In our study, pathological changes were generally more susceptible to ICA. This indicates the importance of screening the rheological parameters of subjects with MetS for the prevention and treatment of cerebrovascular disease.

SUMMARY The aim of this cross-sectional study was to determine the knowledge, attitudes and behavior of medical students in relation to COVID-19 according to different medical schools and duration of studies. A validated questionnaire was administered to 192 medical students at two universities in Croatia and one from Bosnia and Herzegovina. Fisher-Freeman-Halton and Kruskal-Wallis tests were used to examine differences among study groups. The association of variables was tested with a linear regression model. A negative correlation was found between adherence to measures and attitudes (ß=-0.36; p<0.001). Studying at the University of Zagreb was positively associated with students’ knowledge about COVID-19 (ß=0.24; p=0.033) but negatively with students’ attitudes (ß= 0.26; p=0.013). Compared to the last study year students, second-year students had lower knowledge (ß=-0.28; p=0.040) and statistically nonsignificant negative attitudes (ß=-0.24; p=0.055). Fifth-year students had more negative attitudes (ß=-0.24; p=0.008) compared to sixth-year students. The association between knowledge and attitudes was weak and statistically borderline nonsignificant (ß=0.14; p=0.056). The lack of association between knowledge and attitudes requires additional research to identify the potential factors that favor the formation of attitudes toward appropriate protection against COVID-19.

This study demonstrates the effectiveness of propidium iodide as a reliable marker for detecting dead or dying cells in frozen liver tissue sections. By comparing propidium iodide staining with the widely used Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, both methods showed consistent results in disease models such as alcohol-induced fibrosis and Western diet-induced fatty liver. Additionally, propidium iodide was successfully co-stained with other fluorescent markers, like phalloidin (for actin filaments) and antibodies targeting collagen, enabling detailed spatial analysis of dying cells within tissue. This multiplex approach allows for a deeper understanding of tissue organization and cell death localization, particularly in complex conditions like liver fibrosis. Moreover, our results suggest that propidium iodide staining can be applied beyond current models, offering a more accessible and cost-effective alternative to traditional methods, like TUNEL. Furthermore, its integration with other markers enables simultaneous analysis of immune responses and tissue damage, making it a powerful tool for future studies on liver disease and other inflammatory conditions. This technique has the potential to advance research into disease mechanisms and improve the evaluation of novel therapeutic strategies targeting tissue regeneration and inflammation control.

This article examines the multifaceted implications of community service as a criminal sanction within the legal framework of Bosnia and Herzegovina. Grounded in an interdisciplinary approach, it integrates legal analysis, economic evaluation, and psychological perspectives to provide a comprehensive understanding of this alternative sanction. The legal analysis delves into the statutory provisions and judicial practices governing community service, assessing its alignment with international human rights standards and its effectiveness in promoting restorative justice. The economic evaluation leverages statistical data to measure the impact of community service on the national economy, including cost-benefit analyses and its potential to alleviate the financial burdens on the penal system. In exploring the psychological aspects, the article investigates the rehabilitative potential of community service. The article highlights the role of community service in fostering a sense of responsibility, improving self-esteem, and reducing recidivism rates. It also considers the challenges and limitations of implementing this sanction, including potential stigmatization and the necessity for adequate support systems. Through a thorough analysis of these dimensions, the article aims to contribute to the ongoing discourse on criminal justice reform in Bosnia and Herzegovina.

SUMMARY The aim of the present study was to assess mild cognitive impairment (MCI) and cardiometabolic risk factors (CMRF) in Bosnian and Herzegovinian patients with heart failure (HF). This study included 80 patients with HF and 40 healthy controls. Montreal Cognitive Assessment (MoCA) testing was used to evaluate cognitive function. Abdominal obesity was assessed by waist circumference, and hypertension was assessed by the auscultatory method. Data on other CMRF and comorbidities, such as diabetes, smoking, alcohol consumption, and atrial fibrillation (AF), were gathered with a specially designed questionnaire. Lipids, C-reactive protein (CRP), and fibrinogen were assessed with standard laboratory methods. Student, Mann-Whitney, and Chi-square tests were used to determine significant differences between groups. Associations between categorical variables and correlation coefficients were assessed by the Chi-square and Spearman test, respectively. The prevalence of MCI in patients with HF was 77.5%. We found significant associations between MCI and diabetes, hypertension, AF, and smoking in patients with HF. We found no significant associations between MCI, abdominal obesity, and alcohol consumption. A significant positive correlation between MCI and total cholesterol was observed in patients with HF. Furthermore, a lower MoCA score was associated with higher values of CRP and fibrinogen in HF patients. The present study showed a high prevalence of MCI in Bosnian and Herzegovinian HF patients as well as its association with various CMRFs. These results suggest it is necessary to begin MCI screening in HF patients, especially since data from the literature point to improvement in cognitive performance with appropriate HF and concomitant CMRF treatment.

SUMMARY This study aimed to evaluate retinal nerve fiber layer thickness in exfoliation syndrome (XFS), present unilaterally, using optical coherence tomography (OCT). This prospective study included 90 examinees with unilateral syndrome. However, examinees with higher intraocular pressure or findings implicative of glaucoma were excluded from the study, as well as examinees with optic nerve changes. In individuals with unilateral XFS, OCT findings were compared between the two groups: the affected eye group and the fellow eye group. The study results show that the average thinning of the retinal nerve fiber layer, especially in the inferior and superior quadrants, has not resulted in visual field defects in examinees with unilateral XFS. In the group of eyes without XFS, 85.55% exhibited reference inferior quadrant thickness values, and 91.11% exhibited reference superior quadrant thickness values. In the group of eyes with manifest XFS, 82.22% exhibited reference inferior quadrant thickness values, and 88.88% exhibited reference superior quadrant thickness values. Most examinees in both groups had normal average retinal nerve fiber layer (RNFL) thickness (72.22%). In examinees with clinically unilateral XFS, RNFL thinning occurs in both eyes before XFS becomes bilateral and before hypertensive intraocular pressure can be measured.

The favorable characteristics of veneer boards—plywood—enable their wide application. There is also the possibility of enhancing plywood, such as by coating it with various films, applying coatings, reinforcing it with fibers from different materials, and using improved adhesive formulas. Basalt fibers, as a natural and environmentally friendly material, are used in various forms with quite good characteristics. Results from various tests conducted in recent years indicate an improvement in the mechanical properties of composite boards, including plywood reinforced with fibers like basalt fibers. These tests were focused on determining the position and contribution of basalt fibers in the board’s structure, as well as the application of certain environmentally friendly adhesives. For this study, samples of composite material based on wood, specifically plywood reinforced with a basalt mesh, were prepared. The basalt mesh was placed within the plywood structure in various combinations of position and amount. Subsequently, a three-point bending strength test was conducted to determine the impact of the basalt mesh on the strength of the plywood. The increase in strength opens up possibilities for expanded use, material savings, and a reduction in the overall weight of the structure, which is crucial in certain applications of such boards.

The applications of light emitting diodes (LED) as a red light therapy (RLT) source for the management of various conditions such as wound treatment, control of inflammation and pain have been growing continually. Despite its extensive medical application, the effects of RLT on living cells are still highly contested. This study is conducted to test the effects of RLT using combined LED source with 660 nm (red) and 850 nm (near infrared) light on cultured human lymphocytes in vitro. To analyze the effect of RLT on human peripheral blood lymphocyte’s proliferation, the mitotic index (cytostatic effect) is monitored under different irradiation exposure time parameters and conditions. This value indicates how a particular treatment affected cell division, either proliferatively, inhibitory, or had no effect at all. The interpretation of the results of the mitotic index is done in relation to the mitotic index of the untreated (unirradiated) control cells. Our data shows higher lymphocyte proliferation for all of the irradiated samples, and is particularly enhanced by multiple exposures to red light. The effectiveness of RLT on cell activity is of importance in determination of suitable treatment for diseases related to the immune system. To better understand the molecular and metabolic mechanisms involved in red LED-induced photobiomodulation, the study will be extended to investigate the RLT effect on cell protein synthesis.
