Abstract The goal of this research was to determine the effects of programmed work on the development of specific motor skills in young soccer players. The sample of subjects in this research were football players aged 11 and 12 and they were divided into two equal groups of 30 entities. All participants are involved in the regular training process in their football clubs. The research problem was to determine whether there are positive effects of programmed work on the development of specific motor skills. A total of 6 variables from the area of specific motor skills were used in the research. The experimental work program was carried out over a period of three months and included 38 training units. After initial testing and successfully implemented programmed work and final testing, a significant impact of programmed work on the development of specific motor skills was determined. Specific motor skills that were evaluated on 6 variables in the experimental group showed a significant difference on 4 variables. Keywords: specific motor abilities, work program, training effects, young soccer players

Aim To assess the association of single nucleotide polymorphisms (SNPs) in the ACE2 and TMPRSS2 genes with COVID-19 severity and key biomarkers. Methods The study involved 750 COVID-19 patients from Bosnia and Herzegovina, divided into three groups: mild, moderate, and severe cases. Genetic variations within the ACE2 (rs2285666) and TMPRSS2 (rs2070788) genes were examined with real-time polymerase chain reaction. Biochemical markers were determined with standard procedures. Results There was a significant difference in the rs2070788 genotype distribution between patients with mild and moderate symptoms, but not between other groups. For the rs2285666 polymorphism, no significant difference in genotype distribution was found. In patients with mild symptoms, carriers of the GG genotype of rs2070788 had significantly higher total bilirubin levels than carriers of the AA genotype. Similarly, carriers of the TT genotype of rs2285666 had significantly higher activated partial thromboplastin time and international normalized ratio, and lower lactate dehydrogenase levels compared with the CC genotype. Among patients with severe symptoms, carriers of the GG genotype showed significantly higher potassium levels than carriers of the AA genotype, while carriers of the TT genotype showed significantly higher erythrocyte count as well as hemoglobin and hematocrit levels compared with the CC genotype. Conclusion This study highlights the role of genetic factors, particularly SNPs in the ACE2 and TMPRSS2 genes, in determining COVID-19 severity, aiding patient risk assessment and prognosis.

Abstract The methodology for the evaluation of long-term exposure to the overhead line magnetic field is presented, in this paper. The developed methodology is based on the ambient temperature measurements and phase conductors’ height measurements to find a linear regression model to determine phase conductors’ height changes for different ambient temperatures. Based on the overhead transmission line geometry, and datasets about historical overhead line phase current intensity values and ambient temperatures long-term magnetic field exposure can be determined. For magnetic flux density determination, a method based on artificial neural networks is used. The methodology is applied to the case study of overhead line that connect substations Sarajevo 10 and Sarajevo 20. A period of one year is analyzed and magnetic flux density values are determined. The obtained results indicate that during the analyzed period for significant amounts of time magnetic flux density values surpass the recommended values for long-term exposure.

Forests play an important role in adapting to and mitigating the negative effects of climate change and environmental degradation through sustainable forest management. In Europe and North America, where private forest ownership dominates, private forest owners play a crucial role in achieving diverse policy objectives. Given the importance of private forest owner cooperation to support the sustainable management and the achievement of policy goals, this paper systematically reviewed the international scientific publication on private forest owners (PFOs) cooperation using bibliometric network analysis complemented with a literature review to examine the development over the last two decades (2000–2021) and to determine where the trend of the research has been heading. The analysis provided a general overview of PFOs cooperation and focus more specifically on two main aspects of PFOs cooperation: “Reasons for joining forest owners’ organizations” and “Factors influencing PFOs cooperation”. The data was retrieved from the Scopus database and analysed using the VOSviewer software. The results showed that the number of publications on PFOs’ cooperation is more or less constant and that the most prolific authors’ institutions in this topic area come from the United States, Finland, Sweden and Germany. The keyword cluster analysis showed that there are three topic oriented clusters for both aspects of PFOs’ cooperation – “Reasons for joining forest owners’ organizations” and “Factors influencing PFOs cooperation”, while the trend of keywords showed a change in the perspective of PFOs’ cooperation over time: from cooperation for “timber production and supplying to the market” to cooperation for “multifunctional and sustainable forest management”, “biodiversity conservation” and “climate change mitigation”. The results also showed the influence of forest policy on PFOs cooperation.

Introduction: Vaccines for protection against 10 infectious diseases are available in the Program of Regular Immunization in the Federation of Bosnia and Herzegovina. These vaccines save the lives of up to 3 million people worldwide every year. The latest report of the Institute of Public Health of the Federation of Bosnia and Herzegovina on regular immunization carried out during 2020 shows that the rate of vaccination of children during the 2019 coronavirus disease (COVID-19) pandemic with regular vaccines has decreased compared to previous years. Such a situation in the health system leads to a potential risk of outbreaks of infectious diseases that are prevented by vaccination.Objective: To examine the impact of the COVID-19 pandemic on the regular immunization of children in the Mostar Health Center.Materials and methods: A retrospective cross-sectional epidemiological study was conducted. Data on regular immunization of children from theMostar Health Center, Herzegovina-Neretva County in the Federation of Bosnia and Herzegovina from 2017, 2018, 2021 and 2022 were used.Results: A statistically significant difference was obtained in vaccination against measles, mumps and rubella during a period of four years. Vaccination with the mentioned vaccines was significantly higher in 2017 and 2018 than in 2021 and 2022.Conclusion: It was shown that the COVID-19 pandemic affected the regular immunization of children in the Mostar Health Center.Keywords: regular immunization of children, COVID 19 pandemic, MMR vaccine, Mostar

ntroduction: The thyroid hormone secretion disorders may be hyperthyroidism (reduced TSH levels and increased levels of FT3 and FT4) and subclinical hyperthyroidism (decreased concentration of TSH with normal FT3 and FT4).Aim: To investigate levels of thyroid hormones (TSH, FT3, and FT4) in patients with hyperthyroidism or subclinical hyperthyroidism treated at Tuzla Blue Clinic.Materials and methods:The study included 120 patients divided into three groups: a control group, groups with respondents who have hyperthyroidism, and a group of patients with subclinical hyperthyroidism. The concentrations of the hormones TSH, FT3, and FT4 were analyzed. The determination was carried out on the device IMMULITE 1 Siemens using the immunochemistry method. Results:TSH between our group investigated the existence of significant statistical differences between the control group and the group with hyperthyroidism (p<0.0001) and between the control group and the group withsubclinical hyperthyroidism (p=0.0001), and the parameter FT3 showed that a statistically significant difference exists between the control group and the group with hyperthyroidism (p<0.0001), and between patients with hyperthyroidism andsubclinical hyperthyroidism (p<0.0001). For FT4, we found a statistically significant difference between the control group and the group with hyperthyroidism (p<0.0001) and between groups with hyperthyroidism and subclinical hyperthyroidism (p <0.0001).Conclusions: The concentration of TSH is reduced in both hyperthyroidism and subclinical hyperthyroidism. The serum concentrations of FT3 and FT4 are elevated in hyperthyroidism, while in subclinical hyperthyroidism, the serum concentrations of FT3 and FT4 stand in the reference area.Keywords:Thyrotropin, thyroxine, TSH, FT3, FT4, hyperthyroidism

Simple Summary This study explores hypoxia-inducible factors (HIFs) in glioblastoma development, progression, and treatment. Reviewing 104 relevant studies, it highlights diverse global contributions, with China leading at 23.1%. The most productive year was 2019, contributing 11.5% of the studies. Key factors studied included HIF1α, HIF2α, osteopontin, and cavolin-1, involving pathways such as GLUT1, GLUT3, VEGF, PI3K-Akt-mTOR, and ROS. HIF expression correlates with glioblastoma progression, survival, neovascularization, glucose metabolism, migration, and invasion. Overcoming treatment resistance and the lack of biomarkers is crucial for integrating HIF-related therapies into glioblastoma treatment to improve patient outcomes. Abstract Background: The study aims to investigate the role of hypoxia-inducible factors (HIFs) in the development, progression, and therapeutic potential of glioblastomas. Methodology: The study, following PRISMA guidelines, systematically examined hypoxia and HIFs in glioblastoma using MEDLINE (PubMed), Web of Science, and Scopus. A total of 104 relevant studies underwent data extraction. Results: Among the 104 studies, global contributions were diverse, with China leading at 23.1%. The most productive year was 2019, accounting for 11.5%. Hypoxia-inducible factor 1 alpha (HIF1α) was frequently studied, followed by hypoxia-inducible factor 2 alpha (HIF2α), osteopontin, and cavolin-1. Commonly associated factors and pathways include glucose transporter 1 (GLUT1) and glucose transporter 3 (GLUT3) receptors, vascular endothelial growth factor (VEGF), phosphoinositide 3-kinase (PI3K)-Akt-mechanistic target of rapamycin (mTOR) pathway, and reactive oxygen species (ROS). HIF expression correlates with various glioblastoma hallmarks, including progression, survival, neovascularization, glucose metabolism, migration, and invasion. Conclusion: Overcoming challenges such as treatment resistance and the absence of biomarkers is critical for the effective integration of HIF-related therapies into the treatment of glioblastoma with the aim of optimizing patient outcomes.

Hereditary cardiomyopathies include a diverse spectrum of myocardial disorders characterized by mechanical and electrical abnormalities, among which hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM) are distinguished. This paper dives into the genetic foundations of these conditions, with a focus on mutations in genes encoding sarcomere proteins, thin filament proteins, and calcium homeostasis regulators. The familial aggregation of cardiomyopathies underscores the substantial genetic component, with autosomal dominant inheritance patterns predominant in some cases. Genetic testing and counseling emerge as pivotal tools for early diagnosis, risk assessment, and the formulation of personalized treatment strategies. The integration of genetic insights into clinical management holds promise for improving patient outcomes and reducing disease burden. Further analysis of the molecular mechanisms underlying hereditary cardiomyopathies is critical for identifying novel therapeutic targets and advancing precision medicine approaches. By comprehensively exploring the genetic underpinnings of cardiomyopathies, this paper contributes to our understanding of these complex diseases and highlights the potential for innovative interventions to enhance patient care in the field of cardiovascular medicine.

Introduction: Influenza is an acute, infectious disease of the human respiratory system, caused byinfluenza viruses. Since it is a vaccine-preventable disease, medical students as future health professionals should be involved in programs promoting the importance of flu vaccination.Aim: Compare knowledge, attitude and practice of vaccination against influenza among students of the firstand sixthyear of School of Medicine of University of Mostar.Subjects and methods: The study included a total of81 students of the School of Medicine of the University of Mostar. The data were collected using a questionnaire that consists from demographic data of the respondents andtwenty questions with the offered answers about the knowledge, attitude and practice of vaccination against influenza.Results: Sixth-year students showed greater knowledge about contraindications for vaccination. Both groups of students showed mainly positive attitudes about influenza vaccination. No surveyed student was vaccinated against influenza and many of them reasoned that influenza is not a serious illness.Conclusions: Despite good knowledge and mostly positive attitudes about influenza vaccination, no student who participated in the study was vaccinated against influenza. Therefore, it would be useful for medical students to provide additional information about the importance of illness prevention, because they represent an important part of the future workforce in the health system, that will affect the global attitudes of vaccination.Keywords: influenza, vaccination, knowledge, practice, students

Background and Objectives: Cancer is associated with an increased risk of acute ischemic stroke (AIS) and venous thromboembolism. The role of a cardiac right-to-left shunt (RLS) as a surrogate parameter for paradoxical embolism in cancer-related strokes is uncertain. We sought to investigate the relationship between the presence of an RLS and cancer in AIS patients. Methods: We included consecutive AIS patients hospitalized at our tertiary stroke center between January 2015 and December 2020 with available RLS status as detected on transesophageal echocardiography (TEE). Active cancers were retrospectively identified and the association with RLS was assessed with multivariable logistic regression and inverse probability of treatment weighting to minimize the ascertainment bias of having a TEE obtained. Results: Of the 2236 AIS patients included, 103 (4.6%) had active cancer, of whom 24 (23%) were diagnosed with RLS. An RLS was present in 774 out of the 2133 AIS patients without active cancer (36%). After adjustment and weighting, the absence of RLS was associated with active cancer (adjusted odds ratio (aOR) 2.29; 95% confidence interval (CI), 1.14–4.58). When analysis was restricted to patients younger than 60 years of age or those with a high-risk RLS (Risk of Paradoxical Embolism Score ⩾ 6), there was no association between RLS and cancer (aOR, 3.07; 95% CI, 0.79–11.88 and aOR, 0.56; 95% CI, 0.10–3.10, respectively). Conclusion: RLS was diagnosed less frequently in AIS patients with cancer than in cancer-free patients, suggesting that arterial sources may play a larger role in cancer-related strokes than paradoxical venous embolization. Future studies are needed to validate these findings and evaluate potential therapeutic implications, such as the general indication, or lack thereof, for patent foramen ovale (PFO) closure in this patient population.

We discuss the general theory of radicals of paragraded rings, establish that the ADS-Theorem holds, and characterize paragraded normal radicals. It is known that any special radical of a ring can be described by the appropriate class of modules over that ring. In this note we show that all special paragraded radicals of paragraded rings can be described by the appropriate class of their paragraded modules. * This paper was presented at the International Scientific Conference Graded structures in algebra and their applications, dedicated to the memory of Prof. Marc Krasner, IUCDubrovnik, Croatia, September, 22-24, 2016.

In this paper we prove that there exist paragraded rings which are not graded and we discuss prime and Jacobson radicals of paragraded rings. In particular, we prove that paragraded counterparts of prime and Jacobson radicals are the largest paragraded ideals contained in them. * This paper was presented at the International Scientific Conference Graded structures in algebra and their applications, dedicated to the memory of Prof. Marc Krasner, IUCDubrovnik, Croatia, September, 22-24, 2016.
