People who inject drugs (PWIDs) experience high rates of hepatitis C virus (HCV) infection, primarily due to needle sharing and limited healthcare access, resulting in a disproportionate disease burden within this population. This prospective study evaluated treatment outcomes in 432 adult patients with chronic hepatitis C (CHC) treated with direct-acting antivirals (DAAs) at the University Clinical Center of Serbia. Patients were categorized into two groups based on a history of drug addiction: PWIDs (163, 37.7%) and non-PWIDs (269, 62.3%). The PWID group was further categorized into subpopulations of problematic PWIDs (39, 23.9%), ex-PWIDs (124, 76.1%), and PWIDs on OST (96, 58.9%). The PWID group demonstrated significantly lower treatment adherence, with an intention-to-treat (ITT) rate of 82.8%, compared to 96.3% in the control group (p < 0.001). In contrast, no significant differences were observed in per-protocol (PP) outcomes between the two groups. Additionally, PWIDs were significantly younger (p < 0.001) and had higher rates of psychiatric disorders (p < 0.001), alcohol abuse (p < 0.001), and HCV genotype 1a (p < 0.001). Advanced fibrosis was predictor of PP treatment failure among PWIDs, while mood disorders and alcohol use disorder were associated with interruptions before the scheduled completion time. For non-PWIDs, older age and advanced fibrosis emerged as key predictors of PP treatment failure. The loss to follow-up was most commonly observed in the problematic PWID subgroup (p = 0.001). These findings highlight the importance of addressing barriers in PWIDs through integrated care strategies that concurrently manage addiction and HCV. [ABSTRACT FROM AUTHOR]

Background / Aim: COVID-19 is acute virus disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). It was proclaimed as pandemic starting from March 2020 and is still ongoing. COVID-19 pandemic forced all segments of the society, particularly the health sector, to function in changed and aggravating circumstances and because of the transmission and new strains of the virus it resulted in the change of the number of infected people with peaks and oscillations. Aim of this study was to make analysis of the data related to COVID-19 positive/suspect patients examined in the Primary Healthcare Centre Banja Luka in the period 15 March 2020 - 15 March 2021, which refers to the incidence of the infected persons, sex and age representation, laboratory diagnostics and clinical parameters, applied therapy, as well as the number of patients sent for the hospital treatment. Methods: Data for the analysis were obtained by the retrospective analysis of the statistical data from the electronic medical record of the examined COVID-19 positive/suspect patients in the Outpatient Clinic for Acute Respiratory Infections (ARI) and in the field. Pearson's ch2 test of contingency was used for the comparison of differences of the observed characteristics of the examined groups. Results: Personnel of the Emergency Department (ED) of the Primary Healthcare Centre Banja Luka, in the period 15 March 2020 - 15 March 2021, examined the total of 3,937 COVID-19 positive patients and patients suspect of COVID-19. Out of that number, 3,601 patients were examined in the ED - ARI and 336 patients were examined in the field. The biggest number of patients was registered in November 2020 (768). Male sex prevailed (55.50 %) and patients of 20-50 years of age were most represented. There were 3.10 % of those highly febrile patients and 2.5 % of those with low SpO2 of under 90 %. 14.90 % of patients had higher values of troponin T and 45.50 % of them had higher values of D-dimer. In the field, 69.60 % of patients had pathological changes on lungs and 33.30 % had pathological ECG report. The number of patients sent from the ARI for further diagnostic procedure or hospitalisation to the Clinic for Infectious Diseases of the University Clinical Centre of Banja Luka was 1,191 and 258 patients were sent from the field. Conclusion: For the purpose of preventing the spread of epidemics, the ED reorganised the existing space by introducing temporary clinics - containers for the patients with acute respiratory infections and febrile status, COVID-19 suspects. Clinical parameters changed depending on the new virus strains, as well as on age distribution and infection complications.

LYTIC cycle ,INFECTION ,LIFE cycles (Biology) ,MONONUCLEOSIS ,IMMUNOREGULATION - Abstract
EBV infects more than 90% of people globally, causing lifelong infection. The phases of the EBV life cycle encompass primary infection, latency, and subsequent reactivation or lytic phase. The primary infection usually happens without noticeable symptoms, commonly in early life stages. If it manifests after childhood, it could culminate in infectious mononucleosis. Regarding potential late consequences, EBV is associated with multiple sclerosis, rheumatoid arthritis, chronic active EBV infection, lymphomas, and carcinomas. Previous reports that the lytic phase plays a negligible or merely secondary role in the oncogenesis of EBV-related tumors are steadily losing credibility. The right mechanisms through which the lytic cycle contributes to carcinogenesis are still unclear, but it is now recognized that lytic genes are expressed to some degree in different cancer-type cells, implicating their role here. The lytic infection is a persistent aspect of virus activity, continuously stimulating the immune system. EBV shows different strategies to modulate and avoid the immune system, which is thought to be a key factor in its ability to cause cancer. So, the principal goal of our review is to explore the EBV's lytic phase contribution to oncogenesis. [ABSTRACT FROM AUTHOR]

CHRONIC hepatitis C ,HEPATIC fibrosis ,PUBLIC health ,ANTIVIRAL agents ,COMMUNICABLE diseases - Abstract
This study, conducted at two university-based infectious disease clinics, included 216 patients with chronic hepatitis C. The primary objective was to assess the positive and negative predictive values, sensitivity, and specificity of achieving a sustained virological response (SVR) at 4 weeks compared to 12 weeks post-therapy. The results demonstrated a maximum sensitivity of 100% for achieving SVR at 12 weeks after reaching SVR at 4 weeks for all analyzed genotypes, except for genotype 1b treated with EBR/GZR therapy, where the specificity was 75%. Additionally, younger age and less advanced liver fibrosis were identified as independent predictors of achieving a sustained virological response at both 4 and 12 weeks. The significant normalization of various biochemical parameters was observed after treatment, indicating an overall improvement in liver function. This study suggests that shortening the monitoring period to 4 weeks might be effective for younger patients without significant fibrosis, potentially reducing loss to follow-up, which is a critical issue in HCV treatment. These findings align with the "test and treat" approach. Further research is needed to confirm these findings and incorporate them into official guidelines, which could simplify and enhance the effectiveness of HCV treatment protocols, aiding global efforts to eliminate HCV as a public health issue by 2030.

Background / Aim: More people die each year due to cardiovascular diseases (CVDs) than from any other cause. The most common cause of ischaemic heart diseases (IHD) is atherosclerosis of the coronary arteries. Risk factors for the development of coronary heart disease (CHD) can be preventable and non-preventable. The aim of the study was to determine the frequency of individual risk factors in patients with CHD. Methods: Retrospective analysis included patients with diagnoses of stable angina pectoris (AP), unstable angina pectoris and myocardial infarction - acute coronary syndrome (ACS) and ischaemic cardiomyopathy (iCMP). The prevalence of the following risk factors for IHD was analysed: hypertension, diabetes, obesity, cholesterol, smoking, family history, age and sex. Data were taken from the Register of Patients with Chronic Diseases and Risk Factors and electronic patient records. Results: Of the total number of respondents older than 18, 4.95 % had CHD. Of the 178 patients with IHD, 70 (39.3 %) patients had AP, 60 (33.7 %) patients had ACS and 48 (27.0 %) patients had iCMP. Positive family history had 63.5 % of patients, 72 % were older than 66, 24.1 % were smokers and 74.2 % of patients had elevated blood cholesterol levels. Diabetes mellitus affected 29.2 % of patients, hypertension 88.8 %, and BMI ≥ 25 kg/m2 had 70.8 % of patients. Of the total number of patients with ACS, 68.3 % were men, while higher percentage of women suffered from AP (62.9 %) (p = 0.002). In the age below 65, CHD was more common in men (p = 0.007). Cholesterol was elevated more often in patients with AP than iCMP (p = 0.001). Patients with ACS were more likely to have diabetes mellitus compared to patients with AP and iCMP (p = 0.010). Conclusion: The prevalence of preventable risk factors is alarmingly high. Of particular importance is the timely detection and treatment of risk factors by family physicians and strengthening the personal responsibility of each individual in choosing their lifestyle and active involvement in the therapeutic process.

Background/Aim: The prevention of cardiovascular risk factors and cardiovascular disease management contributes to the cardiovascular mortality reduction. The effects of these activities have been measured by quality indicators. The aim of this study was to determine the effects of family medicine team training workshop and implementation of clinical guidelines on the cardiovascular risk factors and diseases management in primary health care in the Republic of Srpska/Bosnia and Herzegovina. Methods: The "CardioVascular Risk Assessment and Management" study included a sample of 373 teams from 41 primary health care centres trained to provide adequate services and to compare the quality of cardiovascular risk management before and after the training workshop and implementation of clinical guidelines. The comparison was based on nine project defined performance indicators related to hypertension, type 2 diabetes mellitus, hyperlipidaemia, tobacco smoking and obesity. Results: Significant improvements were observed in six indicators after the training workshop and implementation of guidelines. Target values for blood pressure and HbA1c were achieved in over 80 % of patients (82.12 ± 15.81 vs 84.49 ± 12.71 and 84.49 ± 12.71 vs 85.49 ± 24.55; before and after the training workshop, respectively), while the target values for LDL cholesterol were achieved in 54.98 % ± 20.33 before and 57.64 % ± 16.66 after the training workshop. The number of teams that had less than 20 % of recorded data significantly decreased after the training workshop and guidelines implementation, and adequate recording of all indicators was improved. Conclusion: The training workshop of family medicine teams and implementation of clinical guidelines resulted in significant quality improvement of cardiovascular diseases management in primary health care.

Introduction: Traumatic experiences in childhood include maltreatment of an individua aged up to 18, which comprises all kinds of physical and/or emotional abuse and physical and/ or emotional neglect, as well as sexual abuse, which lead to the real or potential health hazard. Aim: The aim of present research was to examine the relationship of childhood trauma with symptoms of depression, anxiety and stress in the general population, as well as to compare the exposure to childhood trauma among the three groups of subjects: non-clinical population, clinical population with affective disorders and clinical population with schizophrenia spectrum psychosis. Materials and methods: Medical documentation of 179 adult subjects (healthy controls 92, affective disorders 35 and subjects with psychosis 52) was retrospectively analyzed, using Childhood Trauma Questionnaire, Depression Anxiety Stress Scale and socio-demographic data. Methods of descriptive statistics, between group differences and correlation analysis were applied for the purpose of the data analysis. Results: In the non-clinical sample, a positive correlation between childhood trauma and DASS (depression, anxiety and stress scale) has been noticed (r = 0,265, p = 0,013). When subtypes of trauma were analyzed in this group, it has been noticed that emotional abuse was associated with sub-depression (β = 0,427, p = 0,003), whereas other types of childhood trauma did not influence DASS scores significantly. In addition, we showed that the overall level of trauma did not differ between subjects with psychosis and those with affective disorders. In comparison to the control group, subjects with psychosis had more emotional and sexual abuse, alongside more emotional and physical neglect (p < 0,05). In affective disorders, only sexual abuse was not higher in comparison to the control group (p = 0,390). Conclusion: This research focused on exposure to childhood trauma in patients with affective and psychotic disorders, showing that early adversities have to be considered as a common risk factor in the etiology of the aforementioned disorders. A timely identification of traumatization in childhood and prevention of its consequences by early interventions are important goals of the prevention of mental diroders in adulthood.

Background We investigated the therapeutic response of tocilizumab (TCZ) therapy in patients with coronavirus disease 2019 (COVID-19) pneumonia. Methods This observational retrospective study included 205 patients with confirmed COVID-19 pneumonia with SpO2˂93% and a markedly increased level of at least two biomarkers of inflammation. The TCZ was given in combination with corticosteroids. Clinical and laboratory results were analyzed and compared before TCZ therapy and 7 d after. Results The mean value of C-reactive protein (CRP) was significantly lower (p=0.001) on the seventh day after administration of TCZ compared with before (10.7 and 173.6 mg/L, respectively). Only in 9/205 (4.3%) patients, the CRP level did not decrease during the week-long period, and this was related to disease progression. The mean level of interleukin-6 before TCZ administration was 88±113 pg/mL, while after it was 32.7±21.7 pg/mL (p=0.01). After 7 d of TCZ therapy, almost 50% of patients who needed high-flow oxygen or ventilation support started to receive low-flow oxygen, while 73/205 (35.6%) patients who received low-flow oxygen before TCZ administration did not receive further oxygen support anymore (p=0.001). Although they received TCZ treatment, 38/205 (18.5%) severely sick patients died. Conclusions Tocilizumab improves clinical outcomes in hospitalized COVID-19 patients. These advantages were evident independent of the patient's comorbidities and were in addition to the advantages of systemic corticosteroids. In COVID-19 patients at risk of cytokine storms, TCZ appears to be an effective therapy choice. [ABSTRACT FROM AUTHOR]

Zdravstvenu pismenost možemo definisati kao lične, kognitivne i socijalne vještine kojima se određuje motivacija i sposobnost pojedinaca da dođu do informacija, razumiju ih i koriste kako bi unaprijedili i održali dobro zdravlje. U procesu pružanja zdravstvene zaštite, zdravstvena pismenost predstavlja zajedničku odgovornost unutar koje pacijenti i zdravstveni radnici moraju komunicirati svako na način da ga onaj drugi razumije, kako bi mogli zajednički i odgovorno donositi odluke. Istraživanje je provedeno s ciljem da se ocijeni pouzdanost i valjanost instrumenta za mjerenje zdravstvene pismenosti, ocijeni zdravstvena pismenost korisnika usluga primarne zdravstvene zaštite na teritoriji Republike Srpske (Bosna i Hercegovina), identifikuju faktori koji su povezani sa zdravstvenom pismenošću i predlože mjere iz domena promocije zdravlja za unapređenje zdravstvene pismenosti stanovništva. Istraživanje je provedeno kao studija presjeka u dva doma zdravlja–Prijedor i Bijeljina, a uzorak je činilo 768 ispitanika. Instrument istraživanja bio je upitnik STOFHLA (Skraćeni test za ispitivanje funkcionalne zdravstvene pismenosti kod odraslog stanovništva–Short Test of Functional Health Literacy in Adults). Pored ovog upitnika, korišten je i upitnik u kome se nalaze pitanja koja obuhvataju: demografske, socijalne i ekonomske karakteristike ispitanika, samoprocjenu zdravlja, korišćenje zdravstvene službe, prisustvo hroničnih bolesti, faktore rizika za zdravlje i zadovoljstvo životom. Podaci su analizirani metodama deskriptivne i inferencijalne statistike. Neadekvatnu i marginalnu zdravstvenu pismenost ima 34,6% naših ispitanika, a adekvatnu 65,4%. Utvrđena je povezanost zdravstvene pismenosti u ispitivanoj populaciji sa starosnom dobi, nivoom obrazovanja, pripadnosti domu zdravlja, mjestom stanovanja i migracionim kretanjima, bračnim statusom, materijalnim stanjem, prisustvom i brojem bolesti, promjenom zdravstvenog stanja i samoprocjenom zdravlja, brojem posjeta porodičnim doktorima i brojem hospitalizacija, nedovoljnom fizičkom aktivnošću i samoprocjenom zadovoljstva životom samih ispitanika... Health literacy can be defined as the combination of personal, cognitive and social skills that determine motivation and ability of individual to capture the information, understand them and use them to improve and maintain good health. In a process of providing health care, health literacy represents mutual responsibility within which patients and physicians have to communicate in a comprehensible way, in order to mutually and responsibly make decisions. The goals of the research were the following: to assess reliability and validity of instruments that measure health literacy; assess health literacy of primary health care user on a territory of Republic of Srpska (Bosnia and Herzegovina); identify factors that are associated with health literacy; propose measures from a domain of health promotion in order to improve health literacy of population. The research was conducted as a study of intersection in two Primary health care centers Prijedor and Bijeljina, and a sample was consisted of 768 respondents. The instrument of the study was a query STOFHLA (Short Test of Functional Health Literacy in Adults). Besides this query, another query was used that consists of questions which cover demographic, social and economic characteristics of respondent, self-perception of health, use of health services, presence of chronic diseases, life habits and health risk factors and life satisfaction. Data were analyzed by methods of descriptive and inferential statistics. Inadequate and marginal health literacy possess 34.6% of our respondents, whereas adequate possess 65.4%. A correlation of health literacy in target population was affirmed with age, educational level, utilization of health services, place of residence and migrations, marital status, material status, presence and number of illnesses, health condition changes and self-perception of health, number of visits to a family physician and number of hospitalizations, insufficient physical activity and self-perception of life satisfaction of respondents...

Introduction: Bilateral facial nerve palsy (FNP) is a rare condition that is idiopathic in only 20%. FNP is the most common cranial neuropathy in West Nile neuroinvasive disease (WNND) but is usually unilateral and only a few cases of bilateral FNP have been reported. Case: We present a case of a 65-year-old woman with confirmed WNND and simultaneous bilateral FNP. Results: In August 2022, the patient presented with ataxia, gait instability, tremor, fever, and vomiting. Following admission, due to her cerebrospinal fluid analyses she was diagnosed with WNV encephalitis. Her initial symptoms subsided, but on the 17th day of the disease, right FNP was observed. Three days later bilateral FNP developed, predominantly on the right side, with bilateral otalgia. Further diagnostic was performed but no other aetiology that could contribute to FNP was found. The patient was treated with a 3-day metilprednisolone course, followed by 60 mg of prednisone with dose tapering for 12 days. One month later she was discharged with significant regression of the left and slight regression of the right FNP. Subsequent physical therapy was conducted. The patient's neurological status gradually improved and 4 months after the first symptoms onset, her neurological examination was normal. Conclusions: WNND should be included in the differential diagnosis of acquired bilateral FNP. It can result in full recovery, but unfavorable course is also possible. [ABSTRACT FROM AUTHOR]

Depresija je visokoprevalentno, multifaktorijalno i heterogeno psihijatrijsko oboljenje kompleksne neurobiološke osnove. S obzirom da veliki broj pacijenata (30– 40%) ne postiže remisiju bolesti uprkos antidepresivnoj terapiji, patofiziologija depresije i mehanizmi delovanja antidepresiva i danas su aktuelne problematike iako se intenzivno istražuju decenijama unazad. Brojne studije ukazuju da hronični psihosocijalni stres, vodeći sredinski faktor rizika za razvoj depresije, izaziva oksidativni stres i inflamaciju u mozgu, procese koji imaju važnu ulogu u etiopatofiziologiji ovog oboljenja. Pored toga, sve je više podataka koji pokazuju da je disregulacija γ-aminobuterna kiselina (GABA) sistema u mozgu povezana sa depresijom. U radu su analizirani efekti antidepresiva fluoksetina i atipičnog antipsihotika klozapina na glutation (GSH)-zavisni antioksidativni sistem i parametre inflamacije u hipokampusu i prečeonoj zoni kore cerebruma, moždanim regionima posebno osetljivim na stres. Takođe, ispitan je uticaj ovih lekova na GABA signalizaciju u medijalnoj prečeonoj zoni kore cerebruma, kao i njihova hepatotoksičnost. Ovi efekti su istraživani na životinjskom modelu depresije koji se zasniva na hroničnom izlaganju psihosocijalnom stresoru. Odrasli mužjaci pacova Wistar soja su podvrgavani 21- dnevnoj izolaciji, a fluoksetin i klozapin su davani stresiranim pacovima tokom izolacije, kao i nestresiranim (kontrolnim) pacovima u periodu od 21 dana. Hronična izolacija je dovela do promena u ponašanju koje nalikuju depresivnom i anksioznom, kompromitovala antioksidativnu odbranu posredovanu glutation peroksidazom i izazvala porast nivoa faktora nekroze tumora α (TNF-α) u hipokampusu. Takođe, izolacija je uzrokovala smanjenje koncentracije GSH, aktivaciju nuklearnog faktora-κB i porast nivoa medijatora inflamacije ciklooksigenaze-2 (COX- 2), interleukina-1β i TNF-α u prečeonoj zoni kore cerebruma. Fluoksetin i klozapin su onemogućili razvoj promena u ponašanju i proinflamatorne procese u obe ispitivane moždane strukture kod izolovanih pacova. Što se tiče GSH-zavisnog sistema, fluoksetin je pokazao protektivni efekat ali samo u prečeonoj zoni kore cerebruma pacova... Depression is a highly prevalent, multifactorial and heterogeneous disorder with complex neurobiology. Large numbers of patients (30–40%) do not achieve disease remission despite receiving antidepressive therapy. Thus, despite the decades of research, the pathophysiology of depression and mechanisms of antidepressants’ actions are ongoing and widespread issues. A growing body of evidence indicates that psychosocial stress, the leading environmental risk factor, causes oxidative stress and inflammation in the brain and that these processes have important role in the pathophysiology of depression. In addition, dysregulation of γ-aminobutyric acid (GABA)-ergic system is becoming increasingly associated with this disorder. In this study, we analyzed the effects of antidepressant fluoxetine and atypical antipsychotic clozapine on the glutathione (GSH)-dependent antioxidative system and parameters of inflammation in hippocampus and prefrontal cortex, brain regions particularly sensitive to stress. Besides, we examined the effects of drugs on the GABAergic signalization, as well as their hepatotoxicity. These effects were investigated in an animal model of depression based on chronic psychosocial stress. Adult male Wistar rats were isolated for 21 days and fluoxetine and clozapine were applied to the stressed rats during isolation, as well as to non-stressed rats for 21 days. Chronic isolation caused depressive- i anxiety-like behaviors, compromised glutathione peroxidase-mediated antioxidative defense and caused increase in tumor necrosis factor α (TNF-α) levels in hippocampus. Besides, isolation decreased GSH levels, activated nuclear factor-κB and elevated cyclooxygenase-2 (COX-2), interleukin-1β i TNF-α levels in prefrontal cortex. Fluoxetine and clozapine prevented behavioral changes and proinflammatory events in both examined brain structures in isolated rats. Regarding GSH-dependent defense, fluoxetine showed protective effects, which were restricted to the prefrontal cortex. These results indicate the significant role of proinflammatory molecular changes in the development of depressive symptoms, as well as the importance of the anti-inflammatory properties of fluoxetine and clozapine in their prevention...

- Abstract
Zdravstvenu pismenost možemo definisati kao lične, kognitivne i socijalne vještine kojima se određuje motivacija i sposobnost pojedinaca da dođu do informacija, razumiju ih i koriste kako bi unaprijedili i održali dobro zdravlje. U procesu pružanja zdravstvene zaštite, zdravstvena pismenost predstavlja zajedničku odgovornost unutar koje pacijenti i zdravstveni radnici moraju komunicirati svako na način da ga onaj drugi razumije, kako bi mogli zajednički i odgovorno donositi odluke. Istraživanje je provedeno s ciljem da se ocijeni pouzdanost i valjanost instrumenta za mjerenje zdravstvene pismenosti, ocijeni zdravstvena pismenost korisnika usluga primarne zdravstvene zaštite na teritoriji Republike Srpske (Bosna i Hercegovina), identifikuju faktori koji su povezani sa zdravstvenom pismenošću i predlože mjere iz domena promocije zdravlja za unapređenje zdravstvene pismenosti stanovništva. Istraživanje je provedeno kao studija presjeka u dva doma zdravlja–Prijedor i Bijeljina, a uzorak je činilo 768 ispitanika. Instrument istraživanja bio je upitnik STOFHLA (Skraćeni test za ispitivanje funkcionalne zdravstvene pismenosti kod odraslog stanovništva–Short Test of Functional Health Literacy in Adults). Pored ovog upitnika, korišten je i upitnik u kome se nalaze pitanja koja obuhvataju: demografske, socijalne i ekonomske karakteristike ispitanika, samoprocjenu zdravlja, korišćenje zdravstvene službe, prisustvo hroničnih bolesti, faktore rizika za zdravlje i zadovoljstvo životom. Podaci su analizirani metodama deskriptivne i inferencijalne statistike. Neadekvatnu i marginalnu zdravstvenu pismenost ima 34,6% naših ispitanika, a adekvatnu 65,4%. Utvrđena je povezanost zdravstvene pismenosti u ispitivanoj populaciji sa starosnom dobi, nivoom obrazovanja, pripadnosti domu zdravlja, mjestom stanovanja i migracionim kretanjima, bračnim statusom, materijalnim stanjem, prisustvom i brojem bolesti, promjenom zdravstvenog stanja i samoprocjenom zdravlja, brojem posjeta porodičnim dok, Health literacy can be defined as the combination of personal, cognitive and social skills that determine motivation and ability of individual to capture the information, understand them and use them to improve and maintain good health. In a process of providing health care, health literacy represents mutual responsibility within which patients and physicians have to communicate in a comprehensible way, in order to mutually and responsibly make decisions. The goals of the research were the following: to assess reliability and validity of instruments that measure health literacy; assess health literacy of primary health care user on a territory of Republic of Srpska (Bosnia and Herzegovina); identify factors that are associated with health literacy; propose measures from a domain of health promotion in order to improve health literacy of population. The research was conducted as a study of intersection in two Primary health care centers Prijedor and Bijeljina, and a sample was consisted of 768 respondents. The instrument of the study was a query STOFHLA (Short Test of Functional Health Literacy in Adults). Besides this query, another query was used that consists of questions which cover demographic, social and economic characteristics of respondent, self-perception of health, use of health services, presence of chronic diseases, life habits and health risk factors and life satisfaction. Data were analyzed by methods of descriptive and inferential statistics. Inadequate and marginal health literacy possess 34.6% of our respondents, whereas adequate possess 65.4%. A correlation of health literacy in target population was affirmed with age, educational level, utilization of health services, place of residence and migrations, marital status, material status, presence and number of illnesses, health condition changes and self-perception of health, number of visits to a family physician and number of hospitalizations, insufficient physical activity and self-perception of l

- Abstract
The production of levan by Bacillus licheniformis NS032 in a medium based on sugar beet molasses was studied. High polysaccharide yields were produced by using diluted molasses (100–140 g/L of total sugars) with the addition of commercial sucrose up to 200 g/L of total sugars, as well as K2HPO4. A levan yield of 53.2 g/L was obtained on a medium optimized by response surface methodology, containing 62.6% of sugar originating from molasses, and 4.66 g/L of phosphate, with initial pH value of 7.2. In comparison to the media with 200 and 400 g/L sucrose, in the molasses optimized medium, the observed bacterial growth was faster, while the maximum production of polysaccharide was achieved over a shorter time interval (48 h). The polysaccharide produced in molasses medium had a weight average molecular weight of 5.82 × 106 Da, degree of branching 12.68%, viscosity of 0.24 dL/g, and based on methylation analysis and NMR data, it did not significantly differ from levan obtained in the medium with 200 g/L sucrose. © 2018 Elsevier B.V.

- Abstract
Screens of antioxidant activity (AA) of various natural products have been a focus of the research community worldwide. This work aimed to differentiate selected samples of Merlot wines originated from Montenegro, with regard to phenolic profile and antioxidant capacity studied by survival rate, total sulfhydryl groups and activities of glutathione peroxidase (GPx), glutathione reductase and catalase in H2O2-stressed Saccharomyces cerevisiae cells. In this study, DPPH assay was also performed. Higher total phenolic content leads to an enhanced AA under both conditions. The same trend was observed for catechin and gallic acid, the most abundant phenolics in the examined wine samples. Finally, the findings of an Artificial Neural Network (ANN) model were in a good agreement (r(2) = 0.978) with the experimental data. All tested samples exhibited a protective effect in H2O2-stressed yeast cells. Pre-treatment with examined wines increased survival in H2O2-stressed cells and shifted antioxidative defense towards GPx-mediated defense. Finally, sensitivity analysis of obtained ANN model highlights the complexity of the impact that variations in the concentrations of specific phenolic components have on the antioxidant defense system.

animal structures - Abstract
Exposure of an organism to chronic social isolation (CSIS) causes modulation of antioxidant defense system in the brain which has been shown to have important role in depression. Fluoxetine (Flx) is the first-line treatment for depression; however, precise mechanism of its action still remains elusive. The aim of this study was to investigate the effect of 3 weeks of Flx treatment on malondialdehyde (MDA) level, an oxidative stress parameter as well as on the activities of GSH-dependent antioxidative enzymes in the hippocampus of rats exposed to 6 weeks of CSIS. Increased MDA content following CSIS and Flx treatment (controls or CSIS) of rats, suggests on hippocampal oxidative damage. CSIS induced reduction of hippocampal glutathione-S-transferase that was reversed by Flx treatment, as well as an increase in glutathione peroxidase/reductase activities. The present study contributes to our understanding of the mechanisms that underlie the antidepressant activity of Flx in rats exposed to CSIS, an animal model of depression.

- Abstract
Olanzapine is an antipsychotic proved to be effective in stress associated psychiatric diseases, but its effect on the liver, main site of drug metabolism,still remain unclear. We investigated the effects of chronic treatment of olanzapine (three-week) on the malondialdehyde (MDA) content and protein expression and activity of antioxidant enzyme catalase (CAT) in the liver of rats exposed to chronic social isolation (CSIS) (six-week), an animal model of depression. The increased cytosolic MDA content in both vehicle-and olanzapine-treated CSIS animals suggests oxidative stress. Increased CAT activityin vehicle-treated CSIS animals, which was not consistent with its protein expression, suggests induction of antioxidant defense mechanisms,while olanzapine significantly reduced CAT activity in CSIS group. Data revealed that although olanzapine treatment reversed the alterations in CAT activity, it has the ability to cause hepatotoxicity, as indicatedby increased MDA content.

- Abstract
Brain oxidative stress and neuroinflammation are implicated in psychiatric disorders. Thus, it is important to investigate the effects of individual psychotropic agents on antioxidative defense and proinflammatory mediators in brain regions associated with these disorders. Psychosocial stress is recognized as a threat to mental health, and the hippocampus is a primary target of stress-related damage. Chronic social isolation (CSIS) is a mild psychosocial stress used to model the pathophysiology of depression. We examined the antioxidative and anti-inflammatory potential of the antidepressant fluoxetine (FLX) and atypical antipsychotic clozapine (CLZ) in the hippocampus in the CSIS model of depression. We measured the effects of FLX and CLZ on depressive- and anxiety-like behaviors in non-stressed rats and rats exposed to 21d of CSIS. We further evaluated the content of reduced glutathione (GSH), the protein expression and activity of the GSH-related enzymes, the subcellular localization of nuclear factor-kappa B (NF-kappa B)and protein levels of proinflammatory mediators cyclooxygenase-2 (COX-2), interleukin-lbeta (IL-1 beta), and tumor necrosis factor-alpha (TNF-alpha) in these groups of rats. CSIS resulted in an increase in depressive- and anxiety-like behaviors that corresponded with compromised glutathione peroxidase (GPx)-mediated antioxidative defense and increased TNF-alpha, but not with changes in NF-kappa B, IL-1 beta and COX-2 levels. FLX and CLZ, applied during CSIS, prevented the behavioral changes associated with CSIS, and inhibited the increase in TNF-alpha, but did not affect GPx-mediated antioxidative defense. Furthermore, both drugs decreased hippocampal GPx activity when applied to non-stressed rats. These results emphasize the significance of hippocampal TNF-alpha-mediated proinflammmatory signaling in the pathophysiology of depressive symptoms and the importance of the anti-inflammatory action of both FLX and CLZ in the prevention of these sympto

- Abstract
Duloxetine (DLX) is antidepressantfor the treatment of depression,but its effect on the liver, a primary site for drug metabolism, has yet to be determined.The effect of 3 weeks of DLX treatment onprotein carbonyl groups and activities of GSH-dependent defense including reduced glutathione (GSH), glutathione peroxidase (GPx) and glutathione S-transferase (GST) in liver of rats exposed to 6 weeks of chronic social isolation (CSIS), an animal model of depression, were investigated. CSIS induced increase in protein carbonyl content, which wasdecreasedby DLX treatment. We noticed increase in GPx and GST activity in DLX-treated (controls and CSIS) rats and CSIS group, whereby GPx activity was significantly higher in DLX-compared to vehicle-treatedCSIS rats. Results indicate protective effect of DLX against CSIS-induced oxidative damage of hepatic proteins, which may be due to intensified protective mechanisms mediated by GSH-dependent defense.

- Abstract
Chronic psychosocial stress is a risk factor for depression. As the liver is a primary organ for drug activation and detoxification, the effect of chronic administration of olanzapine on rat hepatic glutathione (GSH)-dependent defense system including GSH, glutathione peroxidase (GPx) and glutathione reductase (GLR), following 21d of chronic social isolation stress (CSIS), an animal model of depression, was investigated. Increased GSH content in olanzapine-treated controls was found. Protein levels of GPx were increased in both vehicle- and olanzapine-treated chronically-isolated animals while significant increase in GPx activity was seen only in olanzapine-treated chronically-isolated animals. Reduced activity of GLR in CSIS group that was not in correspondence with its protein level was increased by olanzapine. The results imply that chronic administration of olanzapine reverts the alternations in hepatic GSH-dependent defense of stressed rats caused by CSIS.

- Abstract
Chronic exposure to psychosocial stress is implicated in the pathophysiology of depression. We investigated the effect of 21d of chronic social isolation (CSIS) stress (an animal model of depression) and/or chronic administration of fluoxetine (15 mg/kg/day), an antidepressant, on GSH content, protein expression and activity of glutathione peroxidase (GPx) and glutathione reductase (GLR) in the cytosolic fraction of rat hippocampus. CSIS stress caused reduced GPx and GLR protein expression which was not prevented with fluoxetine treatment. Moreover, fluoxetine administration intensified reduction of these proteins expression. Decreased GSH content, GPx and GLR activity was also found in chronically-isolated animals (vehicle- or fluoxetine treated). Data indicate that fluoxetine not only failed to prevent CSIS-induced changes but itself compromised GSHdependent defense system in control animals.

- Abstract
Changes in glutathione (GSH)-related systems are implicated in depressive disorders. Since chronic psychosocial stress contributes to depression, we investigated the effects of 21d of chronic social isolation (CSIS) stress, an animal model of depression, as well as chronic administration of clozapine, an atypical antipsychotic, on GSH content, glutathione peroxidase (GPx) and glutathione reductase (GLR) in the prefrontal cortex of rats. Increased GPx protein expression and its activity in clozapine-treated (controls or chronically-isolated) rats as well as in CSIS group were found. Nonetheless, clozapine administration caused decrease in GSH content but no effects on GLR in controls and CSIS group. Data indicate that CSIS compromises GSH-dependent redox system promoting oxidative stress in rat prefrontal cortex which can’t be protected by clozapine. Moreover, clozapine administration in controls has a harmful side effect on this redox system.

- Abstract
Recent data concerning antiphospholipid syndrome (APS) induction have shown that beta(2)-glycoprotein I (beta(2)GPI) binds lipopolysaccharide (LPS), which results in conformational changes, exposition of a cryptic epitope and possible pathological anti-beta(2)GPI antibody production. In order to investigate the effects of LPS on the induction of APS-related pathology, we performed hyperimmunization of BALB/c and C57BL/6 mice with LPS, alone or in combination with tetanus toxoid (TTd), a protein structurally similar to beta(2)GPI. We report that, although high affinity pathological anti-beta(2)GPI antibodies were produced in all groups of animals, the reproductive pathology was recorded only in mice that received both LPS and TTd, implying on the important roles of both infections and molecular mimicry in APS pathogenesis. Moreover, APS-related reproductive pathology was more pronounced in BALB/c (lowered fertility and fecundity) than C57BL/6 mice (lowered fecundity), which correlated well with the disruption in natural antibody network observed in BALB/c mouse strain.

- Abstract
Chronic oxidative stress plays an important role in depression. The aim of present study was to examine the stress-induced changes in serum corticosterone (CORT) levels, cytosolic protein carbonyl groups, malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NO) and total superoxide dismutase (SOD) activity in the prefrontal cortex versus hippocampus of male Wistar rats exposed to acute (2 h of immobilization or cold), chronic (21d of social isolation) stress, and their combination (chronic + acute stress). The subcellular distribution of nuclear factor-kappa B (NF-kappa B) and cytosolic cyclooxygenase 2 (COX-2) protein expressions were also examined. Depressive- and anxiety-like behaviors were assessed via the forced swim, sucrose preference, and marble burying tests in chronically isolated rats. Although both acute stressors resulted in elevated CORT, increased MDA in the prefrontal cortex and NF-kappa B activation accompanied by increased NO in the hippocampus were detected only following acute cold stress. Chronic isolation resulted in no change in CORT levels, but disabled appropriate response to novel acute stress and led to depressive- and anxiety-like behaviors. Increased oxidative/nitrosative stress markers, likely by NF-kappa B nuclear translocation and concomitant COX-2 upregulation, associated with decreased SOD activity and GSH levels, suggested the existence of oxidative stress in the prefrontal cortex. In contrast, hippocampus was less susceptible to oxidative damage showing only increase in protein carbonyl groups and depleted GSH. Taken together, the prefrontal cortex seems to be more sensitive to oxidative stress than the hippocampus following chronic isolation stress, which may be relevant for further research related to stress-induced depressive-like behavior.

- Abstract
Chronic exposure to stress contributes to the etiology of mood disorders, and the liver as a target organ of antidepressant and antipsychotic drug metabolism is vulnerable to drug-induced toxicity. We investigated the effects of chronic administration of fluoxetine (15 mg/kg/day) or clozapine (20 mg/kg/day) on liver injury via the measurement of liver enzymes, oxidative stress and histopathology in rats exposed to chronic social isolation (21 days), an animal model of depression, and controls. The activity of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), the liver content of carbonyl groups, malonyldialdehyde (MDA), reduced glutathione (GSH), cytosolic glutathione S-transferase (GST) and nitric oxide (NO) metabolites were determined. We also characterized nuclear factor-kappa B (NF-kappa B), cyclooxygenase-2 (COX-2) and CuZn-superoxide dismutase (CuZnSOD) protein expression as well as histopathological changes. Increased serum ALT activity in chronically-isolated and control animals treated with both drugs was found while increased AST activity was observed only in fluoxetine-treated rats (chronically-isolated and controls). Increased carbonyl content, MDA, GST activity and decreased GSH levels in drug-treated controls/chronically-isolated animals suggest a link between drugs and hepatic oxidative stress. Increased NO levels associated with NF-kappa B activation and the concomitant increased COX-2 expression together with compromised CuZnSOD expression in clozapine-treated chronically-isolated rats likely reinforce oxidative stress, observed by increased lipid peroxidation and GSH depletion. In contrast, fluoxetine reduced NO levels in chronically-isolated rats. Isolation induced oxidative stress but histological changes were similar to those observed in vehicle-treated controls. Chronic administration of fluoxetine in both chronically-isolated and control animals resulted in more or less normal hepatic architecture, while clozapine in b

- Abstract
Changes in glutathione (GSH)-related systems are implicated in depressive disorders. Since chronic psychosocial stress contributes to depression, we investigated the effects of 21d of chronic social isolation (CSIS) stress, an animal model of depression, as well as chronic administration of clozapine, an atypical antipsychotic, on GSH content, glutathione peroxidase (GPx) and glutathione reductase (GLR) in the prefrontal cortex of rats. Increased GPx protein expression and its activity in clozapine-treated (controls or chronically-isolated) rats as well as in CSIS group were found. Nonetheless, clozapine administration caused decrease in GSH content but no effects on GLR in controls and CSIS group. Data indicate that CSIS compromises GSH-dependent redox system promoting oxidative stress in rat prefrontal cortex which can’t be protected by clozapine. Moreover, clozapine administration in controls has a harmful side effect on this redox system.
