Background: Zearalenone is a widely spread mycotoxin, contaminant of most cereal grains. It has uterotropic, estrogenic and anabolic activity in farm animals. The results are hormonal disbalances as hyperestrogenism, Zearalenone inhibits follicle-stimulating hormone production, thus supressing ovarian follicle development and ovulation. Also, it induces oxidative stress. Melatonin acts as a potent natural antioxidant and regulates the reproductive function by modification of steroidogenesis.

Objective: The present study was conducted to provide detailed qualitative histological analysis of uterus of female rats treated with zearalenone and melatonin and contribute to better understanding of the topic.

Methods: Forty adult, female Wistar rats were equally divided into five groups: Z group - zearalenone, 0,3 mg/kg, i.g.; M group - melatonin, 10 mg/kg, i.p.; ZM group -concomitant application of zearalenone and melatonin in the same dosing regimen, VZ group-zearalenone vehiculum/sunflower oil, i.g. and MZ group-melatonin vehiculum/5% ethanol in Ringer, i.p. Animals were treated daily for 28 consecutive days. After that period, all animals were sacrificed to obtain samples for qualitative histological analysis using the light microscope.

Results: Zearalenone led to the alterations of the uterine structures, predominantly in the endometrium that were characterized by metaplasia and hypertrophy of the epithelial cells and hypercellularity of the stroma. In the myometrium, zearalenone induced hypertrophy and hyperplasia of the myocytes.

Conclusion: Melatonin, when applied together with zearalenone, blocked the adverse effects of the zearalenone.

Background: Uncontrolled type 2 diabetes mellitus (T2DM) is widely recognized as a significant risk factor for the emergence of cardiovascular events. Early risk assessment, especially for coronary artery disease, is crucial to starting therapeutic strategies to lower cardiovascular risk.

Objective: To assess cardiovascular risk in patients with type 2 diabetes mellitus.

Methods: 64 patients were divided into groups according to age, gender, disease duration, glucoregulation, and applied treatment. The SCORE table was used to quantify cardiovascular risk.

Results: Our research showed that cardiovascular risk in patients with diabetes mellitus increases with age (rho = 0.458; p = 0.0001; p <0.05) and is higher in men (rho = -0.417; p <0,0001). It has been found that patients with a longer duration of diabetes mellitus have a higher cardiovascular risk (rho = 0.266; p = 0.032). Patients with better glucoregulation had a slightly lower cardiovascular risk, but correlation was statistically insignificant. No statistically significant correlation was observed between applied therapy and cardiovascular risk.

Conclusion: Good control and treatment of T2DM is of crucial importance for reducing cardiovascular risk.

Background: Leptospirosis is the most common zoonotic disease in Tuzla Canton. Objective: Determine the influence of environmental and precipitation factors on the incidence of leptospirosis.

Methods: A retrospective study included 80 patients with leptospirosis. Data on precipitation were obtained from the online database of Federal Hydrometeorological Institute of BiH. OpenStreetMap (OSM) was used for spatial analysis; patients were geolocated and put on a map. Statistical data processing included basic tests of descriptive statistics.

Results: In the period between 01.01.2014 and 31.12.2014, 80 patients with leptospirosis confirmed by clinical and serological testing were hospitalized in the Clinic for Infectious Diseases of the University Clinical Center Tuzla. Gender wise, out of 80 patients, 54 were male (67.5% of the total), and 26 were female (32.5%). More patients lived in the countryside: 64/80 (or 89%). The largest number of patients was engaged in agriculture and animal husbandry: 48/80 (or 60%), mostly cows 32/80 (40%), chickens 12/80 (15%), sheep 4/80 (5%) and pigs 3/80 (3.8%). Of the total number of patients, 50 (or 62.5%) had contact with domestic animals: dogs 10/80 (or 12.5%) and cats 5/80 (or 6.3%). Half of 53/80 (66.3%) patients had contact with flooded areas in the study period. The increase in leptospirosis diagnosed patients in the City of Srebrenik was statistically significant for 2014 (p<0.01).

Conclusion: Leptospirosis in one of the neglected infectious diseases in our area, but the proven increase in the number of infected people after heavy rainfall obliges us to control the risks associated with this disease.

Background: Prenatal screening offers crucial information about the pregnancy, although sometimes brings forth ethical issues and potentially difficult decisions for pregnant women. Ultrasound screening during pregnancy is both of particular importance and a great challenge.

Objective: The objective of this study is to assess women's knowledge and expectations regarding prenatal ultrasound screening in Greece.

Methods: The study was conducted between May 2019 and January 2020. Three hundred pregnant women >18 years of age with complete antenatal routine screening, were invited to participate. The questionnaire contained sociodemographic and obstetric history information and highlighted the background knowledge of pregnant women in prenatal screening.

Results: In this study, women with university or technological education mentioned in a greater proportion the importance of prenatal screening regarding prevention and treatment of intrauterine diseases. The belief that the pain or sorrow to give birth to a disabled child or one with a genetic disorder might lead parents to the decision to terminate the pregnancy, was supported more by women with a higher educational level.

Conclusion: Pregnant women place a great deal of trust in their physician, as a source of information for the fetal well-being. The majority consider prenatal testing mandatory for that matter. Finally, an association between women who abide with prenatal screening and their educational level was noted. Thus, it's more common women who have a higher educational level to seek prenatal screening, than those with lower education level.

Background: Sternotomy is a classical surgical procedure for approaching the heart and mediastinum. Sternotomy wound infections can be superficial or deep.

Objective: The aim of this study is to retrospectively evaluate the results of two treatments for deep sternal wound infection (DSWI), closed treatment (debridement, refixation and retrosternal irrigation) and open treatment (debridement, VAC therapy and then pectoral flap).

Methods: Retrospective analysis of two methods of treatment of DSWI in the period of six years. The first group (G1): surgical debridement, sternum fixation with, if necessary, retrosternal irrigation. The second group (G2): surgical debridement, open sternum with VAC therapy and subsequent pectoral flap with sternum refixation if necessary. Sternotomy wound infection will be classified according to the depth of the affected areas and the time of infection. Risk factors, outcome, local findings, number of revisions, number of hospital treatment days, types of isolates, etiology of sternotomy, time from onset of sternal instability to first surgical treatment will be observed.

Results: The number of patients with DSWI was 16, which represents 1% of all sternotomy in the observed period. Mortality in the DSWI group was 35%. Surgical myocardial revascularization was initially performed in 73% of patients with DSWI. Two risk factors for DSWI were in 32% of patients and 25% had diabetes mellitus. The average time for DSWI development in G1 was 10 days (min 0, max 30) and in G2 was 20 days (min 12, max 30). Number of revisions in G1 (min 1, max 2), G2 (min 1, max 3). Average number of hospital days were in G1 23.50 days (SD 13.15), and in G2 38.17 days (SD 28.65). The sternum was osteomyelitic and fragmented in 20% of patients. More than one revision occurred in 40% of patients. The main initial isolate was Enterococcus faecalis in 27% of all DSWI (dominantly in G1 2/3 of all).

Conclusion: We found that there is no statistically significant difference in observed treatments, and that each treatment has its own indications. We suggested that studies with a larger sample are needed for a definite opinion on this issue.

Background: Human papillomavirus is a sexually transmitted infection and it is estimated that 75% of all women have been exposed to HPV infection in a certain period of life. High-risk types of HPV are considered to be one of the major causes of cervical cancer and its precursor intraepithelial neoplasia.

Objective: The aim of this study was to investigate the degree of HPV infections and to provide more data on HPV genotype distribution among women in Bosnia and Herzegovina (B&H).

Methods: Number of 375 samples were collected from different polyclinics in Sarajevo and were analyzed by Alea Genetic Center using Genomed f-HPV typing™ multiplex Fluorescent PCR kit for human papillomavirus genotyping. DNA required for this method is extracted from cervical swabs and amplified using a multiplex PCR reaction containing a set of 16 fluorescently labeled primers that recognize 16 HPV types. 14 HPV types are classified as high-risk (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68) and two are low-risk (6 and 11) HPV types.

Results: Results showed that in the years 2018, 2019, and 2021, HPV type 16 is predominant causing the high-risk factor for CIN1, CIN2, CIN3, and cervical cancer development. HPV 18 infection rates decreased during the last four years of study. HPV 6 infection rates increased during that period of time.

Conclusion: HPV 16 and HPV 18 are almost completely preventable by vaccination implying that the number of diagnosed cervical cancers in B&H could be much lower in the next decades if the HPV vaccination routine immunization program starts soon.

Background: Bruxism is defined as a movement disorder of the masticatory system leading to serious problem in the integrity of the oral dentition; it is characterized by teeth grinding and clenching and has been typically classified into three types: a) bruxism occurring during sleep, b) awake-related bruxism, and c) mixed sleep/awake-related bruxism.

Objective: The aim of this study was to assess any bone apposition in the mandibular angle in a group of adult patients diagnosed with bruxism using digital panoramic radiographs.

Methods: In the sample of 150 digital panoramic radiographs of 66 women and 84 men with an age range of 24-78 years and diagnosed with bruxism were evaluated.

Results: Among the 300 mandibular angles evaluated, 156 (52%) showed bone apposition against 144 (48%) who did not.

Conclusion: The changes in the mandibular angle, especially bone apposition, can help diagnosing long term bruxism on panoramic radiographs.

Background: Polyglandular autoimmune syndrome type III (PAS III) is combination two most common autoimmune disease: Diabetes mellytus type 1 (DM1) and autoimmune thyroid disease (AITD).

Objectives: The aims of the study were a) to define conection between polymorphism of CTLA-4 gene, rs 231775 with PAS III; b) to establish the conection of inherited genotype with severity of clinical features; and c) to estimate the rate of risk for severe clinical presentation among subgroups in study population.

Methods: This research included 50 subjects with diagnosed PAS III syndrome, wich are on treatment in clinic for Nuclear medicine and andocrinology KCUS. As methods of research has used: hystory of disesase AND clinical examination. As material is used blood sample. From blood sample DNA was isolated withn Qiamp- DNA-mini kit, with accopanied protocol.

Results: In our study, 50 patients with polyglandular autoimmune syndrome type III (PAS III) were examined, and in the study population had 26 female subjects and 24 male subjects. The average age of the participants was 31.64 years, and in the subgroups: group GWT (G-wild type) the average age was 30.20 years, group GM (G-mutated) 32.40 years and group GH (G-heterozygote) 30 , 60 years. Using the Chi-square test, the association between the polymorphism rs231775 and PAS-III was demonstrated, x2 (2.100) = 18.258, where p < 0.0001. Using the Chi-square test, the association between the rs231775 polymorphism and the severity of the clinical picture, x2 (2.50) = 8.531, where p< 0.0140 was proved. The CTLA-4 rs231775 genotypes were also assessed for disease severity.

Conclusion: This study suggests that CTLA-4 expression plays a key role in balancing the immune system as well as the response against one's own tissues, and thus in the regulation of autoimmune diseases.

Background: Lipids and lipoproteins are significantly involved in maintaining structural and functional components of the human brain and neurons, but their role in the development of Alzheimer's disease (AD) and vascular dementia (VD) remains unclear.

Objective: The aim of the present study was to explore the differences in the standard and novel lipid profile parameters in patients with AD and VD, stratified by the degree of cognitive impairment (CI).

Methods: Present study included 66 patients with AD, 50 patients with VD, and 60 control subjects. For an evaluation of the global cognitive function the Montreal Cognitive Assessment (MoCA) test was used. In order to distinguish patients with VD from those with AD the Hachinski ischemic score was used. Plasma total cholesterol (TC), high-density lipoprotein -cholesterol (HDL-C), and triglycerides (TG) levels were determined using standard enzymatic colorimetric techniques, whereas the Friedewald formula was used to calculate low-density lipoprotein-cholesterol (LDL-C) levels. The non-traditional lipid indices such as TG/HDL-C, TC/HDL-C, and LDL-C/HDL-C ratio were separately calculated. The differences between the groups were analyzed with the Kruskal Wallis test followed by the Mann-Whitney test or with ANOVA followed by the Tuckey posthoc test.

Results: Results of the conducted study have found that the patients in AD group with moderate CI and patients in AD group with severe CI exhibited significantly lower levels of serum TC, TG, LDL-C, VLDL-C, Non- HDL-C, atherogenic index, TG/HDL-C, TC/HDL-C and LDL-C/HDL-C compared to cognitively normal control subjects. Moreover, patients in VD group with severe and moderate CI had significantly lower level of TG compared to control group of subjects. Our results have also shown that patients in AD group with moderate CI had significantly lower level of TC, TG, LDL-C, Non-HDL-C, atherogenic index, TG/HDL-C, TC/HDL-C compared to VD patients with moderate CI. In addition, patients in AD group with severe CI had significantly lower level of TC, LDL-C, Non-HDL-C and TC/HDL-C compared to VD patients with severe CI.

Conclusion: The results of this study have shown dysregulation of lipid metabolism in AD and VD patients with different degree of CI. In both moderate and in severe CI, patients with AD had lower levels of majority of standard and novel lipid parameters compared to patients with VD. Further larger prospective studies are required to elucidate the accuracy of standard and novel lipid parameters in the assessment of different degree of CI in AD and VD.

Background: Periodontal complications are one of the common side effects associated with orthodontic therapy.

Objective: This study aimed to evaluate the periodontal changes in patients before, during, and after the therapy with a fixed orthodontic appliance.

Methods: Out of 38 healthy adolescents with permanent dentition who were indicated for fixed orthodontic therapy were included in this study. Patients were selected from Class I, treated by non-extraction methods, by using conventional orthodontic braces. After their examination and treatment by an orthodontist, the patients were referred to the periodontist before the placement of a fixed orthodontic appliance. The patients underwent the application of a periodontal anamnestic-diagnostic protocol, and the clinical-radiological evaluation. After a fixed orthodontic appliance was placed, the respondents were referred to the periodontist for regular mandatory check-ups, initially, after three months, and later on-after 6 months, after 1 year and after 2 years until the end of orthodontic therapy.

Results: An increase in the mean value of the Plaque Index and Sulcus Bleeding Index was found at each check-up after the placement of a fixed orthodontic appliance. There is a statistically significant difference in the presence of gingival hyperplasia found by monitoring the changes after three and six months, and after one and two years following the start of orthodontic therapy.

Conclusion: The assessment of periodontal changes in patients before, during and after the completion of fixed orthodontic therapy revealed that there is a strong need for mutual and close cooperation between orthodontist and periodontist during orthodontic therapy.
