Assessment of Sexual Health and Use of Cervical Cancer Screening among the Female Working Population.

Background: Cervical cancer occupies a significant place in the overall structure of morbidity and mortality in developing countries. We focused on the sexual health and use of cervical cancer screening among the female working population of reproductive age in Central Serbia. Methods: The research was conducted as a cross-sectional study, according to the methodology Stepwise approach to noncommunicable disease risk factor surveillance WHO. The study population consisted of 1182 female working population aged 18-49 years, living on the territory of Central Serbia. The method of simple random sampling was utilized in the research itself. An anonymous standardized questionnaire was used as a research tool. Results: During the first sexual intercourse, 38.9% of the participants reported not having used any of the contraceptives, whereas 74.5% of the participants reported not having used them during their last sexual intercourse and 26.1% of the respondents reported not having had a single Pap smear in their lifetime. The multivariate logistic regression analysis singled out the following factors in women who reported not having done a Pap smear in their lifetime as the most significant ones: age - the youngest age group (OR = 3.30, CI = 1.80-6.04), unemployment (OR = 2.87, CI = 0.07-3.40), women who had never been married or had never been in a common-law marriage (OR = 2.55, CI = 1.40-4.66) and individuals with a medium education level (OR = 2.63, CI = 1.67-4.14). Conclusion: In Serbia, all the activities should be directed towards increasing the levels of awareness and knowledge on sexual health and cervical cancer screening services.

Exposure to Stress and Burnout Syndrome in Healthcare Workers, Expert Workers, Professional Associates, and Associates in Social Service Institutions.

Background and Objectives: Workplace burnout syndrome is often as sociated with particular aspects of certain job positions, especially those that entail working with people with special needs. The burnout syndrome in healthcare jobs is a serious problem that has grown into an epidemic among healthcare workers and associates. The aim of this research is to assess the presence of stress and burnout syndrome at work with healthcare workers, expert workers, professional associates, and associates in social service institutions in Belgrade. Materials and Methods: This research was conducted in the form of a cross-sectional study of a representative sample in social institutions in Belgrade. It was conducted from March to the end of June of 2023. The sample of the study had 491 participants. The questionnaires used were a structured instrument with social-demographic and social-economic characteristics, workplace characteristics, lifestyle characteristics, and the following questionnaires: DASS-21, Copenhagen, Brief Resilience Scale, and Brief Resilient Coping Scale. Results: The end results indicate the following to be significant risk factors for the occurrence of workplace burnout syndrome: overtime (OR = 2.62; CI = 1.50-4.56), BRS average score (OR = 0.28; CI = 0.17-0.44), DASS21 D heightened depression (OR = 2.09; CI = 1.1-4.04), DASS21 A heightened anxiety (OR = 2.38; CI = 1.34-4.21), and DASS21 S heightened stress (OR = 2.08; CI = 1.11-3.89). The only protective risk factor that stood out was the self-assessment of health levels (OR = 0.60; CI = 0.42-0.85). Conclusion: Overtime is a significant factor associated with workplace burnout. Apart from it, other significant factors associated with workplace burnout were heightened depression, anxiety, and stress levels.

Activity of enzymes in the follicular fluid and outcome of in vitro fertilization.

Defining certain parameters of the oocyte microenvironment that can be simply and quickly detected and that enable differentiation of oocytes that have better or worse quality could potentially increase the efficacy of the in vitro fertilization (IVF) method. Follicular fluid represents the microenvironment for the development of oocytes during different stages of maturation. Enzymes present in the follicular fluid may affect the quality of oocytes. There are inconsistencies in the literature concerning enzyme concentration in follicular fluid. The main aim of this study was to examine whether the concentration of enzymes aspartate aminotransferase, alanine aminotransferase (ALT), alkaline phosphatase, and lactate dehydrogenase in follicular fluid can influence the outcome of IVF. The study included 120 patients who were involved in the process of IVF. We used the follicular fluid obtained after follicular aspiration in the ovaries as biological material for the analysis. The values of enzymes LDL (method-kinetic UV test), aspartate aminotransferase (method-kinetic UV test), ALT (method-kinetic UV test) and alkaline phosphatase (method-colorimetric kinetic test) in the follicular fluid were determined on the analyzer АU 680, Becman Coulter. The criteria of the Istanbul consensus of clinical embryologists were used for the embryo assessment. The software package SPSS 20 was used for the statistical processing of data. The results of follicular fluid sample analysis showed a correlation between ALT concentration in the follicular fluid and IVF outcome. Based on our results, we can conclude that ALT concentration affects the outcome of IVF.

Burnout syndrome among medical nurse-technicians in intensive care units in cardiovascular surgery.

Background: Healthcare workers in intensive care units work under specifically hard conditions compared to healthcare workers who work under regular clinical conditions. In this sense, the research aims at assessing the level of burnout symptomatology among nurse technicians working in intensive care units for cardiovascular surgery and to compare those burnout levels with those recorded for medical technicians working under regular clinical conditions. Method: The research was designed as a cross-sectional study. The sample consisted of nurse technicians working in intensive care units specializing in cardiovascular surgery (70 participants) and nurse technicians working under regular clinical conditions (70 participants) at the Institute for Cardiovascular Diseases "Dedinje," Belgrade, Serbia. To evaluate the manifestation of burnout syndrome at work, the analysis uses the Serbian version of the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). Results: To examine the variances in the average sub-scores for burnout within two groups of medical technicians, the study used Two Independent Samples T-test. The statistically noteworthy differentiation was ascertained for emotional exhaustion and personal accomplishment, but this does not hold true for depersonalization. However, the mean score values across the different burnout levels (low, moderate, high) are similar in two cohorts of respondents (p > 0.05). Conclusion: This study will serve as an impetus for a policy reform focused on ameliorating working conditions and improving healthcare workers' satisfaction and overall healthcare quality.

The impact of the COVID-19 pandemic on the trend of prescribing long-acting injections of paliperidone and risperidone in Central Serbia.

Since the end of 2019, the global spread of COVID-19 has represented a historic event that changed our way of treating patients globally. The use of long-acting injections (LAI) antipsychotics was emphasized. Our goal was to investigate the impact of COVID-19 on the frequency of prescribing LAI and compare it with a period before. All patients (198) who started LAI-risperidone or LAI-paliperidone for the period 2017-2022, in Kragujevac, the city in Central Serbia, were considered. The frequency of prescribing LAI before and during COVID-19 and the total number of prescribed LAI per year were compared. Separately, the frequency of prescribing LAI-R and the frequency of prescribing LAI-P were compared. The significant (p < 0,05) increase in the use of LAI risperidone and paliperidone was in 2020 and 2021 [per year 2017(3), 2018(6), 2019(26), 2020(75), 2021(55), and 2022(33)]. The significant (p < 0,05) increase in monthly and quarterly preparations of LAI paliperidone was in 2020 and 2021 relative to the years before the pandemic. As the pandemic weakened, the inclusion of LAI paliperidone therapy weakened during 2022. A significant increase in usage of LAI risperidone was in 2022, and in 2020 and 2021 was as it was in the period 2017-2019. During COVID-19, especially in years when COVID-19 restriction measures were stricter, there was a significant change in the application method of antipsychotic therapy in favor of LAI. Regardless of the increase in treatment costs, patients' interests and protection were prioritized in the treatment process.

IL-6 of follicular fluid and outcome of in vitro fertilization.

The quality of an oocyte is influenced by its microenvironment, which includes cumulus cells and follicular fluid, as well as cells of the immune system and their products. The ovarian interleukins, which are secreted by the granulosa cells and other immune cells within the ovaries and follicles, regulate various functions between the cells. IL-6 is a cytokine that is present in the follicular fluid and may affect the quality of oocytes. There are some inconsistencies in the literature regarding the concentration of interleukin 6 in the follicular fluid. The main objective of this study was to examine whether the concentration of interleukin 6 in the follicular fluid affects the outcome of IVF. This study involved 83 patients who underwent IVF. Follicular fluid was used as the biological material for the analysis. Examination of the obtained follicular fluid and collection of oocytes under a stereomicroscope was performed in the embryological laboratory. The concentration of IL-6 in the follicular fluid was analyzed. IVF and ICSI methods were used as the fertilization methods. Pregnancy was confirmed by the positive serum ß-hCG level. The software package SPSS 20 was used for statistical data processing. Analysis of the follicular fluid samples showed a correlation between the concentration of IL-6 in the follicular fluid and the outcome of IVF. The concentration of IL-6 in the follicular fluid was higher in patients with confirmed pregnancy (9.55 ± 7.47 ng/ml). Based on our results, we conclude that the concentration of IL-6 affects the outcome of IVF. If the range of IL-6 concentration is between 3,67 ng/ml and 10 ng/ml, we can expect good IVF outcome with vital pregnancy.

Chlamydia trachomatis screening in resource-limited countries - Comparison of diagnostic accuracy of 3 different assays.

INTRODUCTION: Commercially available assays were evaluated in order to determine diagnostic accuracy of Chlamydia trachomatis specific tests for screening. METHODS: The study included 225 sexually active men and women, who were tested for genital chlamydial infection in Institute of Public Health Kragujevac. Three screening tests were used: direct immunofluorescence (DIF) and rapid lateral immunochromatographic test (RT) for qualitative detection of chlamydial antigens and immunoenzyme (ELISA) test for detection of serum levels of anti-chlamydial IgA and IgG antibodies. Diagnostic efficiency of these tests were determined in relation to results obtained by RT-PCR method. RESULTS: Statistical significance between the results obtained by RT-PCR as a gold standard and DIF, RT and ELISA were analyzed using chi-square (χ2) test. Statistical analysis showed a significant difference between RT-PCR and analyzed screening tests: DIF (χ2 = 303; p < 0.001), RT (χ2 = 4.19; p = 0.041), serum IgA (χ2 = 4.19; p = 0.041) and serum IgG (χ2 = 67; p < 0.001) which indicates poor agreement between these tests. Large numbers of false positive (FP) and false negative (FN) results were observed for all tested assays. According to Youden's index, serum IgG and DIF testing demonstrated the most-balanced sensitivity-specificity rate. RT assay exhibits the highest expanded Youden's index, as well as the best overall diagnostic accuracy. CONCLUSIONS: None of evaluated screening tests can be recommended as individual method for the diagnosis of acute infection. We suppose that RT-PCR is unlikely to be a cost-effective screening strategy within the Serbian health system.

METHOTREXATE AND MYOTREXATE INDUCE APOPTOSIS IN HUMAN MYOMA FIBROBLASTS (T hES CELL LINE) VIA MITOCHONDRIAL PATHWAY.

Uterine leiomyomas (fibroids) are the most common benign tumors in women of reproductive age. Although the local application of low doses of methotrexate (MTX) is used as an effective treatment of the myomas, myotrexate could be a promising new drug. This study investigated the cytotoxic and apoptotic effects of both MTX and myotrexate in human fibroblasts derived from the uterine fibroids (T hES cell line). The myotrexate adduct is an aqueous solution of MTX and L-arginine. Cells were treated with a graded concentrations of both MTX and myothrexate (0.1-16 µM) for 24 h. The cytotoxicity was assayed by MTT test, apoptosis was evaluated by Annexin V-FITC assay and their possible role in apoptosis was determined by immnu- flourescence. Both MTX and myotrexate induced apoptosis in T hES cells in a dose dependent manner (p < 0.001). Myotrexate significantly increased the percentage of AnnexinV positive cells, BAX/Bcl-2 ratio and subsequent caspase-3 activation compared to the MTX treated cells (p < 0.05). Both MTX or myotrexate treatment showed a diffuse staining of cytochrome c indicating its release from mitochondria to the cytosol, suggesting that their mechanisms of action most likely involves the mitochondrial apoptotic pathway.

Dystocia as a cause of untimely cesarean section.

BACKGROUND/AIM: One of the most frequent indications for cesarean section is dystocia. It is impossible to predict, difficult to identify and coincident with the rapid expiry of the expected time, so it is important to point out some mistakes in expecting vaginal delivery. The aim of this study was to examine the frequency and the length of dystocia-related cesarean delivery, as well as the vitality of the newborn immediately after birth. METHODS: A prospective 3-year study was conducted including a total number of 6470 deliveries regardless of whether they were completed using cesarean section after an unsuccessful attempt of spontaneous vaginal delivery or not. The Apgar score, a proved useful tool for the assessment of the vitality of newborn children in the first minute, was used. RESULTS: On the basis of the established indications, 653 (10.10%) of deliveries were completed using cesarean section. Dystocia was the third most common indication for cesarean section (16.38%). Deliveries in which dystocia was established as a diagnosis lasted much longer (p = 0.030) which resulted in weaker vitality of newborn children (p = 0.000) compared to the deliveries ended by spontaneous vaginal delivery. CONCLUSION: This study shows that deliveries caused by dystocia last much longer and newborn children are of weaker vitality compared to other deliveries caused not by dystocia. Decisions concerning cesarean section must be made in a timely fashion.

[Breech presentation at term: caesarean section or vaginal delivery?].

INTRODUCTION: Term breech presentation occurs in 3-4% of all deliveries. Most obstetricians are completely sure how to end delivery when the foetus is in breech presentation, by caesarean section as the only option. OBJECTIVE: The main goal of the paper was to present the method of delivery for term breech presentation analyzed at the Hospital of Gynaecology and Obstetrics and Clinical Centre in Kragujevac, and parameters that influenced the decision on the method of choice to perform delivery with the foetus in breech position. METHODS: During a three-year prospective study, the course and outcome of all term breech deliveries were under followup. The study involved only deliveries in breech presentation, with a trial of labour ending by vaginal delivery, while elective caesarean section due to breech presentation of the foetus was not included in the study. The following parameters were compared: body mass, newborn's first minute Apgar score and head circumference, gestational maturity, gestational age, delivery duration, maternal level of education and maternal parity. RESULTS: Of total 6,470 deliveries, 653 (10.10%) were finalized by caesarean section. Of these, there were 202 (3.12%) term breech presentations, of which 72 (35.64%) women had caesarean and 130 (64.36%) vaginal delivery. A difference was detected in newborn's body mass and head circumference, delivery duration, maternal level of education and parity between pregnancies terminated surgically in comparison to vaginal delivery, while pregnancy duration, maternal age, first minute Apgar score, and most significantly, perinatal morbidity did not show any difference regardless of the method of delivery for term breech presentation. CONCLUSION: With respect of all known parameters, vaginal delivery in breech presentation is also accepted.

[The ultrasonographic diagnosis of fetal encephalocele at 13th gestational week].

BACKGROUND: Encephalocele presents a rare anomaly of central nervous system, developed as a consequence of neural tube closing defect during early embrional development, and it is described by a baggy formation which prolaborates through the pores of the scull, filled with brain tissue, cerebrospinal liquor and entwined with meninges. According to literature search, until this day, the earliest it can be ultrasonically detected is the 13th gestation week, with the appliance of three-dimensional ultrasound. CASE REPORT: We presented 25 years old patient, ultrasonically diagnosed with occipital fetal encephalocela at the 13th gestation week. A gestation sack was located in the right uteral corn of the two-corned uterus with one cervix. The diagnosis was confirmed also by trippled value of alpha-fetoprotein in maternal serum: 75.98 IU/mL. CONCLUSION: Ultrasonic examination is the method of choice for prenatal detection of a fetal anomaly. It is possible to diagnose encephalocele if it prominates above the limits of the scull.

[Attitudes and behaviour of students related to reproductive health].

UNLABELLED: INTRODUCTION One of the features of modern societies is the increase of sexual activity among young people. Sexual activity creates new health problems, or to be more exact, it can result in an unplanned pregnancy and disease induced by sexual contact. MATERIAL AND METHODS: The data for the study were obtained from the questionnaires filled in by students of the Faculty of Medicine and Faculty of Economics in Kragujevac in 2008. Out of 615 students of both sexes included in this questionnaire, 222 students were from the Faculty of Medicine and 393 students from the Faculty of Economics. The questionnaire was designed at the Institute for Public Health "Dr Milan Jovanovic Batut" in 2000 for the project "Health condition, health needs and using of health protection by population in Serbia". RESULTS: The research showed that 41.6% of the students included in the questionnaire had sexual relations; 69.1% of female and 30.9% of male students had sexual experience, i.e. one third and two thirds of the interviewed students attending the Faculty of Economics and of Medicine, respectively. The reason for having the first sexual intercourse was love in 50.4%. Almost 80% of the interviewees used a condom during the first sexual contact. According to the answers, 71.9% of the study sample had one sexual partner. More than half (51.6%) of the students having sexual relations did not use contraceptives. Contraceptives were used more frequently by the students of Medical Faculty (54.3%) than those from the Faculty of Economics (45.7%). CONCLUSION: In order to prevent multiple consequences of ignorance and risky behaviour, it is necessary to inform and educate young people about the reproductive health.

[Histochemical and immunohistochemical analysis of ruptured atherosclerotic abdominal aortic aneurysm wall].

BACKGROUND/AIM: The main complication of the atherosclerotic abdominal aortic aneurysm (AAA) is her rupture that begins with lesion in intima and rupture. The purpose of this work was to determine immunocytochemical and morphofunctional characteristics of the cells in aortic wall in ruptured atherosclerotic abdominal aortic aneurysm. METHOD: During the course of this study, 20 samples of atherosclerotic AAA were analyzed, all of them obtained during authopsy. The samples were fixed in 4% formalin and embedded in paraffin. Sections of 5 microm thickness were stained histochemically (of Heidenhain azan stain and Periodic acid Schiff--PAS stain) and immunocytochemically using a DAKO LSAB+/HRP technique to identify alpha-smooth muscle actin (alpha-SMA), vimentin, myosin heavy chains (MHC), desmin, S-100 protein, CD45 and CD68 (DAKO specification). RESULTS: The results of our study showed that ruptured atherosclerotic AAA is characterized by a complete absence of endothelial cells, the disruption of basal membrane and internal elastic lamina, as well as a presence of the remains of hypocellular complicated atherosclerotic lesion in intima. On the plaque margins, as well as in the media, smooth muscle cells (SMCs) are present, which express a alpha-SMA and vimentin (but without MHC or desmin expression), as well as leukocyte infiltration, and a large number of foam cells. Some of the foam cells show a CD68- immunoreactivity, while the others show vimentin- and S-100 protein-immunoreactivity. Media is thinned out with a disorganized elastic lamellas, while adventitia is characterized by inflammatory inflitrate (infection). CONCLUSION: Rupture of aneurysm occurs from the primary intimal disruption, which spreads into thinned out media and adventitia. Rupture is caused by unstable atherom, hypocellularity, loss of contractile characteristics of smooth muscle cells in intima and media, neovascularization of the media, as well as by the activity of the macrophages in the lesion.
