<p><strong>Introduction. </strong>This study analyzed the factors influencing the outcome of assisted reproductive technology (ART) in women with infertility issues. The investigation focused on endometrial thickness, the number of retrieved oocytes, and the number of obtained embryos as potential predictors of ART success.<br /><strong>Method.</strong> A health-epidemiological questionnaire of general data was created for the purposes of this study. Various statistical methods were applied for data analysis. Descriptive statistical parameters for the observed parameters were pre<br />sented, including the arithmetic mean (M), standard deviation (SD), skewness (Sk), and kurtosis (Ku), to examine deviations from the normal distribution. Multiple regression analysis was applied to investigate the relationships of the independent variables with the dependent variable.<br /><strong>Results. </strong>The study included 100 women of reproductive age. Endometrial thickness was not a significant predictor of ART&nbsp;<br />outcome. Conversely, the number of retrieved oocytes and the number of obtained embryos were identified as significant predictors of ART success. Participants with positive ART outcomes demonstrated a lower number of retrieved oocytes&nbsp;<br />but a higher number of obtained embryos.<br /><strong>Conclusion.</strong> These findings highlight the importance of embryo quality in the implantation process. Further research is&nbsp;<br />needed to better understand this dynamic and to improve infertility treatments.</p>

Psychological violence among adolescents and young adults represents a significant challenge for both public health and the educational system, with long-term consequences for mental well-being. This study aimed to examine the prevalence and forms of psychological violence among individuals aged 12 to 24, as well as their awareness and personal experiences related to this issue. The research was conducted on a sample of 75 participants aged between 12 and 24 years, using a structured questionnaire that included demographic data, experiences with psychological violence, and familiarity with protective responses. The results revealed that a considerable number of participants had been exposed to various forms of psychological violence, including verbal abuse, social exclusion, and rejection. The study provides insight into the extent of psychological violence in this age group and indicates the need for further support measures. The discussion emphasizes the importance of involving students, parents, and teaching staff in efforts aimed at fostering emotional literacy and non-violent communication. Further research and programmatic development are recommended to enhance supportive strategies in school environments.

Svrha rada je da pruži pregled poslovnog okruženja u Bosni i Herce­govini i objasni njegov uticaj na priliv stranih direktnih investicija. U radu će se dalje analizirati struktura, iznosi i priliv stranih direktnih investici­ja koje je Bosna i Hercegovina privukla posljednjih godina. Prema podacima iz izvještaja međunarodnih organizacija, a na osnovu veći­ne pokazatelja, Bosna i Hercegovina i dalje zaostaje za susjednim zemljama. Da bi se stimulisao priliv stranih direktnih investicija, potrebno je stvoriti pre­duslove za njihov veći priliv, ali i stvoriti povoljan poslovni ambijent koji će biti atraktivan za strane investitore. Bosna i Hercegovina mora preduzeti niz aktivnosti, kako bi unaprijedila uku­pnu poslovnu klimu. Koje su to postojeće poslovne prepreke koje treba priori­tetno otkloniti, što bi rezultiralo povećanjem stranih direktnih investicija, ta­kođe će biti predmet razmatranja u ovom radu.

People consumed salt exclusively through food millions of years ago, which amounted to less than 0.5 g/day. Recent researches indicate that the average daily consumption of salt is more than 10 g/day. The general conclusion of studies investigating the relationship between dietary salt intake and blood pressure led to recommendations on reducing salt intake and limiting total intake to 5 g of salt per day by the World Health Organization and the European Safety Agency of Food. Increased salt intake causes suppression of the Renin-Angiotensin-Aldosterone system by reducing sodium renal excretion. Also, an increase in salt intake leads to an increase in the concentration of sodium in the blood, which causes high secretion of vasopressin and causes high blood pressure. Namely, bread is a basic food and is high in salt, but the salt parameter is not mandatory in accordance with the regulations. Today, almost every EU country has different strategies that include recommending salt reduction through food reformulation to reduce the salt content of food, including bread and bakery products. Achieving and maintaining the reduction of the population's salt intake will soon give a great benefit in terms of the prevention of cardiovascular events as the first cause of death globally, then great savings for the health system and an individual.

Introduction. Inhalation of coal dust during blasting in brown coal mines has been shown to lead to a lung disease called pneumoconiosis. There is very little data in the literature on the direct impact of coal on the quality of life of people who work in coal mines as well as the body's immune response to the effects of coal dust. The aim was to examine the immune response to exposure to coal dust in miners in a brown coal mine and whether mine workers have poorer quality of life compared to those not exposed to coal dust. Methods. This is a cross-sectional study among 100 employees in the Brown Coal Mine in Ugljevik, of which 50 of them are exposed to coal dust on a daily basis. Blood samples were taken from all subjects to test for the presence of cytokines IL-2, 4, 5, 9, 10, 13, 17A, 17F, 21, 22, IFN-g and TNF-a. The quality of life of employees was measured using a questionnaire for self-assessment of physical and mental health (36-item Short-Form Health Survey, SF-36). Results. Group of miners had a significantly (p<0.05) higher concentrations of pro-inflammatory cytokines IL-6, IFN-g, IL-17A and IL-22 when compared to the control group. Subjects from the control group had significantly (p<0.05) higher concentrations of anti-inflammatory cytokines IL-4 and IL-10 when compared to the group of miners. The quality of life was significantly (p<0.05) better in the control group when compared to the group of miners. Conclusion. Physical functioning, general health, mental health and Physical component summary were significantly poorer in the group of miners. Exposition to coal dust led to a significant increase in the production of pro-inflammatory cytokines and a decrease in the production of anti-inflammatory cytokines.

Aim To synthesize evidence about the influence of individual antimicrobial stewardship programs (ASP) related to the prevention of Clostridium difficile (C. difficile) infection on primary and secondary outcomes. Methods Relevant databases such as Medline, PUBMED, COCHRANE library and EBSCO were searched from 1 April to 27 April 2017. Additional studies were reached by the manual search for original articles in relevant journals. We included all randomized controlled, quasi-experimental and observational studies, published in the English language from 2007 onward, that evaluated effectiveness of ASP in preventing and controlling C. difficile associated disease (CDAD) among adult inpatients. Results Implementation of ASP interventions was associated with CDAD incidence reduction in 62.5% studies, but no significant differences were reported for the duration of hospitalization, readmission and mortality rate. Improvements in prescribing patterns (decreased antimicrobial use or increased rational use) and microbial outcomes (decreased rates of selected antimicrobial-resistant bacteria) were reported. Evidence on the effects of ASP is mainly limited to the results of studies low in methodological quality with great heterogeneity of outcomes, interventions, and units in which CDAD incidence data were reported. Conclusion Despite the low strength of evidence of reviewed studies, consistency of findings suggest the positive impact of antimicrobial stewardship programs on the prevention and control of nosocomial CDAD. The significance of this problem imposes randomized control trial use as the best instrument to provide highquality evidence. Further studies need to systematically analyse changes in all antibiotic use and its outcomes.

Introduction: Hospital-acquired infections (HAI) and surgical site infections (SSI) are a global public health problem. The aim of the study was to determine the incidence of SSIs at the Surgical Clinics of the University Clinical Centre Banja Luka and to identify risk factors for the development of SSIs. Methods: In order to determine the frequency of SSIs through the incidence compared to the patients operated at the Surgical Clinics of the University Clinical Centre Banja Luka, we conducted a prospective cohort study which encompassed 11.216 operated patients, in the period from November 11th, 2014 to September 30th, 2015. In order to identify risk factors for the development of SSIs, a nested case-control study of risk factors for SSIs was conducted. The study group consisted of patients who were diagnosed with SSIs in the period of monitoring, while the control group was consisted of patients without SSIs who corresponded with the study group in age and sex. Results: The highest values of incidence of SSIs were observed at the Department of Anesthesia and Intensive Care (2.65%), Department of Orthopaedic Surgery (2.48%) and the Department of Vascular Surgery (2.15%), and the lowest ones at the Department of Urology (0.59%). Among the cases of SSIs, deep infections of the surgical site were the most represented (82.7%). Multivariate logistic regression was used to identify the following independent risk factors: length of pore-operative stay in hospital (p=0.000; OR=1.062; 95% CI=1.037-1.087), reintervention (p=0.000; OR=22.409; 95% CI=6.361-79.071) and cotrticosteroids (p=0.023; OR=4.141; 95%CI=1.221-14.047). Conclusion: The incidence of SSIs at the Surgical Clinics of the University Clinical Centre Banja Luka is at the level of hospitals in developed countries. There are a number of risk factors for SSIs, which may be prevented.
