Background: Congenital cytomegalovirus infection (cCMV) is a leading cause of sensorineural hearing loss (SNHL) and neurodevelopmental disabilities in developed countries. Although high cCMV rates have been reported in populations with high seroprevalence, the cCMV prevalence in low/middle-income countries in Europe has not been defined. Objective: To determine cytomegalovirus (CMV) seroprevalence and the cCMV prevalence in Bosnia and Herzegovina. Methods: Between March 2010 and February 2019, 5222 sera samples from patients seen at the University Clinical Hospital Mostar were tested for CMV IgG. The cord blood samples collected from 2091 infants between July 2011 and January 2013 were analyzed for CMV IgG and CMV DNA. The cCMV prevalence was determined by testing saliva swabs from 1293 infants between November 2015 and October 2016. Results: The overall CMV IgG prevalence was 81.4% (95% confidence interval: 0.8–0.82). Significantly higher prevalence was observed among females (84.9%) than in males (77.0%), and the rate increased from 50.8% in the 1 to 5 years group to 97.7% in the group > 65 years old. Most cord blood samples (2091/1925, 92.1%) were CMV IgG positive, and 2 (0.1%) were CMV DNA positive. Of the 1293 saliva swabs, 8 (0.62%; 95% confidence interval: 0.3–1.2) were CMV positive. All 8 infected infants had asymptomatic cCMV, and none had SNHL at 18 months of age. Conclusions: In a highly CMV seropositive population, the prevalence of cCMV was lower compared with that reported from other low/middle-income countries populations. None of the infected infants had symptomatic infection or SNHL at 18 months.

Aim To examine whether there are differences in the experience in giving informed consent of patients whose surgery was elective compared to emergency surgery in the same department. Methods A prospective cross-sectional study was conducted in the Department of Gynaecology and Obstetrics of University Clinical Hospital Mostar during a 6-month period. The sample of respondents consisted of two groups of patients, 145 with elective surgery and 90 patients with emergency surgery. The study was conducted using an anonymous questionnaire. Results Patients in both examined groups were equally satisfied with the procedure of informed consent. Most patients signed the informed consent at the request of a nurse, 195 (83%). During the process of consenting, almost all patients, regardless of whether they had elective or emergency surgery, claimed that they understood the form, which had to be signed, it was important to them, 230 (97.9%), except the patients who had elective surgery, 130 (90.3%), regularly stated that having an opportunity to ask questions was important to them. Respondents with emergency surgery more frequently agreed to sign whatever was in the form, 42 (46.7%). Conclusion Patients who had a planned surgery and patients who had an urgent surgery, mostly declare contentment with the use of informed consent although they did not have the same experience about informed consent.

BACKGROUND The quality of life (QOL) of mothers who have children with cerebral palsy (CP) is significantly worse than in mothers with typically developing children. In available literature we have not found an approach which analyzes the correlation of mothers' personality traits with their QOL and health related quality of life (HrQOL). SUBJECTS AND METHODS The study included 101 mothers of children with CP, aged 4 to 18 years. Mothers' personalities have been assessed by Eysenck EPQ - R questionnaire that determines three personality traits: neuroticism/emotional stability, extroversion/introversion and psychoticism. Maternal HrQOL was assessed by SF-36 questionnaire, Short Form, and their emotional well-being by WHO 5 well-being index. In addition, the influence of mothers' religiosity was also analyzed, using DUREL Religiosity Questionnaire. Motor assessment of children was performed using Gross Motor Function Classification System. The control group consisted of mothers of typically developing children of the same age. RESULTS Participants with high levels of extraversion had better QOL and HrQOL, as opposed to those with high levels of neuroticism and psychoticism, who had worse physical and mental health. The degree of children's motor impairment and mothers' religiosity did not influence QOL. Regression analysis distinguishes the following predictors for better mothers' QOL: better their mental health, greater level of their vitality, extroversion, living with a partner, a lesser degree of children's motor impairment and better their QOL. CONCLUSIONS It is vital to identify the factors that affect QOL of a mother and a child with CP. We consider it justified to regularly conduct mothers' professional monitoring and treatment simultaneously with children's treatment and we propose the protocol for the individual and targeted approach.

AIM To determine the frequency and type of complications in two cohort groups of preterm newborns. SUBJECTS AND METHODS The research involved 100 preterm newborns divided into two groups according to their gestational age: newborns from 24 to 33+6/7 weeks GA and newborns from 34 to 36+6/7 weeks GA. Parameters which were observed with mother were: age, number of births, course and complications in pregnancy. Parameters with infant: gestational age, weight, newborn small for gestational age (IUGR), asphyxia, respiratory distress syndrome, sepsis, hyperbilirubinemia, apnea, anemia, intracranial hemorrhage and metabolic disorder (hypoglycaemia, hypocalcaemia). Research criterion for exclusion was all preterm newborn infants with chromosome anomalies which cause death, fetal death during pregnancy (in utero) and newborns (born after full 37 weeks). RESULTS After dividing exminees according to their gestational age into two groups, the group with higher gestational age (from 34 to 36+6/7 weeks GA) had 76% and the group with lower gestational age (from 24 to 33+6/7 weeks GA) had 24% of infants. The course of pregnancy was pathological in 68% of pregnancies and normal with 32% of pregnncies, the difference is statistically significant. 97% of pregnant woman had pathological course in the group of preterm newborns with lower GA. The most common perinatal complication was hyperbilirubinemia in 42% of cases, while sepsis was present in 1% of infants. The first group of infants (<33 GA) had mostly combination of 3 or more complications in 46% of infants while the other group mostly had hyperbilirubinemia in 50% and combination of complications in 24% of infants. CONCLUSION Perinatal complication occurence depends on premature birth and course of pregnancy. Larger number of complications and harder complications which may result with death are more common in patients with lower gestational age (24 to 33+6/7 weeks GA) than in patients with higher gestational age (34 to 36+6/7 weeks GA).

Abstract We compared the number of CD4-positive (CD4+) and CD8-positive (CD8+) cells in severe and non-severe preeclampsia (PE), and in normal pregnancy. We also evaluated the expression of matrix metalloproteinase 9 (MMP-9) in CD4+ and CD8+ cells. Immunohistochemistry for CD4+ and CD8+ was performed on the decidua basalis of 15 severe and 13 non-severe PE women and compared to decidual tissue of 19 normal pregnancies (control group). Co-expression of MMP-9 with CD8+ and CD4+ cells was determined by double immunofluorescence staining. The median number of CD8+ cells/mm2 was significantly lower for the severe PE group than for the normal pregnancy group, as was the number of CD4+ cells and MMP-9+CD8+ cells. No statistical difference was found between the non-severe PE group and the normal pregnancy group. The significant decrease of CD4+, CD8+ and MMP-9+CD8+ cells at the fetal-maternal interface only in the severe PE group suggests that immunological disorders play a role in the pathophysiology of severe PE.

Abstract Aim: To evaluate the perinatal outcomes of newborns after premature rupture of membranes (PROM) at the term according to the timing of initial antibiotic administration. Material and methods: This is a retrospective, cohort study investigating perinatal outcomes of newborns in pregnant women with PROM at the term who were treated with ampicillin within or after 6 h from the PROM. Statistical analysis was performed using Student’s t-test for continuous variables test and chi-square or for categorical data. Results: The study involved 144 pregnant women with PROM and their newborns, a lower number received antibiotics after birth were in the group who received antibiotics within 6 h of PROM (26.4% versus 73.6%), the mediane values of C-reactive protein were lower (3.0 ± 2.9 mg/l versus 6.1 ± 7.3 mg/l; p < 0.001), their newborns remained shorter in hospital after birth (4.13 versus 4.94; p =0.023) and time between PROM and delivery was shorter (p < 0.001). In group who received prophylactic antibiotics after 6 h of the PROM had significantly higher frequency of infection in newborns (45.3% versus 15.4%), and higher number of chorioamnionitis (9.72% versus 3,47%) compared to group who received antibiotics within 6h. Conclusion: Timely usage of antibiotic prophylaxis and shorter time between PROM and delivery improve perinatal outcomes.

Abstract Aim: The aim of the study is to determine the effect of body mass index in pregnancy on the CRP concentration in pregnant women and their newborn. The results of the study will serve as a guide for a more valid assessment of slightly elevated concentrations of CRP and a potential new guide for the treatment of newborns with antibiotics. Method: The research is a cohort prospective study of 2 groups of pregnant women and their newborn with respect to the body mass index of the pregnant women prior to delivery. The study included 128 pregnant women and their newborn whose serum was analysed to ascertain CRP concentration. Results: The CRP concentration in pregnant women with an elevated BMI was higher than in the pregnant women with normal BMI during pregnancy. The difference is statistically significant (p<0.001). The CRP concentration taken from the umbilical cord and during the second day of life of the newborn of the pregnant women with an elevated BMI was statistically significantly higher than in the newborn of the pregnant women with normal BMI during pregnancy (p<0.001). A repeated blood test conducted between the third and fifth day of life showed that the concentration of CRP in the newborn of both study groups was within referential values. Conclusion: The study indicates a significant correlation between BMI in pregnancy and CRP concentration in pregnant women and their newborn. The results of this study are a potential milepost in addressing the dilemma of whether to administer antibiotics to newborns with elevated CRP values (<20 mg/L) without aggravating their clinical condition. It may be necessary to simply repeat the laboratory tests of CRP in the blood of the newborn in the first days of life and thus follow its dynamics.

Background: The prevalence of gestational diabetes mellitus (GDM), as a complex problem in pregnancy, is increasing all over the world, but most noticeable in developing countries. Aims: To estimate GDM prevalence and associated pregnancy features in the southern part of Bosnia and Herzegovina. Methods: A cross-sectional observational study was conducted from October 2010 through March 2011. A total of 285 pregnant women with singleton pregnancies participated and were asigned to the study in the order they came for their usual ante-natal clinic examination. They underwent an oral glucose tolerance test (OGTT) with 75 g of glucose. Information on OGTT results, maternal characteristics and pregnancy outcomes were collected from database and medical records. Results: Prevalence of GDM was 10.9% according to 1999 World Health Organisation (WHO) diagnostic criteria. Prenatal cigarette smoking, previous GDM, cesarean delivery rate and neonatal hypoglycemia were significantly more frequent in the GDM group compared to the group of pregnancies with normal glucose tolerance (p = 0.015, p < 0.001, p = 0.015, p = 0.002). Conclusion: This study presents a relatively high prevalence of GDM in Bosnia and Herzegovina. There is a need for large well-designed study on GDM prevalence and its other features.

BACKGROUND The student population is at higher risk of acquiring sexual transmitted diseases (STDs) and accounts for a higher incidence of unplanned pregnancies due to a combination of lifestyle and environmental reasons. AIM To determine the attitudes of medical students towards contraception. METHODS A total of 190 students of the School of Medicine of University of Mostar attending four different-academic years participated in this cross-sectional study. Attitudes of participants towards contraception were examined using an anonymous questionnaire. RESULTS Sexually active students accounted for 61.1% of participants, of which 52.6% regularly used contraception. The most common method of contraception was male condom (90.3%). The main reason for contraception was to avoid pregnancy (64.1%). Students with higher medical education (p<0.001) and students with non-religious views (p=0.004) had positive attitudes towards contraception. There were no gender differences on contraception views. CONCLUSION Students with higher medical education and those with non-religious views had positive attitudes towards contraception. Therefore, education on contraception assumes its wider use, which is an important measure to reduce the incidence of STDs and unwanted pregnancies in high-risk population.

Preterm delivery before 37 gestational weeks is a major challenge in perinatal health care. Over the past 30, the incidence of preterm delivery in most developed countries has been about 7–10% of live births. Some evidence shows that this incidence has increased slightly in the past few years, but the rate of birth before 32 weeks' gestation is almost unchanged, at 1-2%. Several factors have contributed to the overall rise in the incidence of preterm delivery. These factors include increased use of assisted reproduction techniques, increasing rates of multiple births, and more obstetric intervention. Progesterone is the key hormone maintaining pregnancy. Numerous progesterone effects can be demonstrated by laboratory studies involving every tissue of the reproductive tract, the myometrium, decidua, cervix, and fetal membranes. In particular, progesterone can alter the response to cytokines, inhibit prostaglandin and nitric oxide synthesis, reduce corticotrophin-releasing hormone (CRH) synthesis, block cervical stromal degradation, and induce cervical stromal matrix protein secretion. By altering both the mechanical and physiologic functions of the cervix, cervical performance may be substantially enhanced by these agents. Presumably, progesterone may alter the rate of cervical stromal degradation via altering secretion of matrix metalloproteases by diminishing prostaglandin and nitric oxide synthesis and minimizing neutrophil recruitment. The diverse aetiology of preterm delivery makes its prediction difficult. A substantial part of unexplained preterm deliveries might be attributable to a deleterious immune response of the mother toward the foetus. A growing body of evidence suggests that progesterone might play a significant role in establishing an adequate immune environment during the early stages of pregnancy. In the presence of progesterone, lymphocytes of pregnant women release a protein named the progesterone induced blocking factor (PIBF)7 which mediates the immunomodulatory and antiabortive effects of progesterone. Immunologic recognition of pregnancy and subsequent activation of maternal immune system result in an upregulation of progesterone receptors on activated lymphocytes among placental cells and CD8+ cells. In the presence of sufficient progesterone levels, these cells synthesize PIBF. Patients at risk of preterm delivery presented increased proinflammatory cytokines, low PIBF, and reduced IL-10 expressions on lymphocytes. PIBF alters the profile of cytokine secretion of activated lymphocytes shifting the balance toward Th2 dominance. During a normal uneventful pregnancy, the concentration of PIBF continuously increases from the 7th to the 37th gestational weeks. After the 41st week of pregnancy, PIBF concentrations dramatically decrease. In patients with a diagnosis of threatened premature labour, studies have shown that PIBF levels failed to increase during pregnancy. Identification of women with risk for preterm delivery would be a key for its prevention. No sufficiently specific marker, however, has so far been found. The diverse aetiology of preterm birth makes its prediction difficult. This special issue will give as some useful information but also questions which are important for our understanding of pathophysiology, prevention, diagnosis, and treatment of preterm birth.

Abstract Objective: To determine thresholds of maternal glycemia at which specific adverse pregnancy outcomes occur in high-risk population. Methods: A total of 1002 pregnant women with risk factors for gestational diabetes mellitus (GDM) underwent an originally modified glucose tolerance test (OGTT) with 75 g of glucose. Information on OGTT results and pregnancy outcomes were collected from database and medical records. Results: Large for gestational age (LGA) newborn, infant’s stay in the neonatal intensive care unit (NICU) >24 h, neonatal hyperbilirubinemia and cesarean section due to cephalopelvic disproportion were identified as specific GDM adverse outcomes. In the study group of participants with one or more specific GDM adverse outcomes, mean glycemic values during the modified OGTT (4.2 ± 1.0 mmol/L at 0 min, 6.8 ± 1.7 mmol/L at 30 min, 7.9 ± 2.1 mmol/L at 60 min, 7.7 ± 2.3 mmol/L at 90 min and 7.5 ± 2.3 mmol/L at 120 min) according to Student’s t-test for independent samples were significantly higher than mean glycemic values in the control group of participants without specific adverse outcomes (p < 0.001, p = 0.02, p < 0.001, p < 0.001, p < 0.001). Conclusion: This study provides additional data that support the acceptance of the newly recommended outcome-based GDM diagnostic criteria.

Pregnancy is followed by many physiologic, organic and psychological changes and disorders, which can become more serious in pregnancy followed by complications, especially in women with pathological conditions during pregnancy. The purpose of this study was to find out and analyze the prevalence and intensity of psychological disorders in women with pathological conditions during pregnancy and compare it with conditions in pregnant women who had normal development of pregnancy. The research is approved by the Ethical committee of the Mostar University Hospital Center, and it was made in accordance with Helsinki declaration and good clinical practices. The research conducted section for pathology of pregnancy of Department for gynecology and obstetrics of the Mostar University Hospital Center. It included 82 pregnant women with disorders in pregnancy developement and control group consisted of pregnant women who had normal development of pregnancy. The research work was conducted from September 2007 to August 2008 in Mostar University Hospital Center. Pregnant women had Standard and laboratory tests, Ultrasound. CTG examinations were done for all pregnant women and additional tests for those women with complications during pregnancy. Pregnant women completed sociobiographical, obstetrical-clinical and psychological SCL 90-R questionnaire. Pregnant women with pathological pregnancy exibited significantly more psychological symptoms in comparison to pregnant women with normal pregnancy (p < 0.001 to p = 0.004). Frequency and intensity of psychical symptoms and disorders statisticly are more characteristic in pathological pregnancy (61%/40.6%). The statistical data indicate a significantly higher score of psychological disorders in those pregnant women with primary school education (p = 0.050), those who take more than 60% carbohydrates (p = 0.001), those with pathological CTG records (p < 0.001), those with pathological ultrasound results (p < 0.001 to 0.216) and those pregnant women with medium obesity and obesity (p = 0.046). Body mass index (BMI) during normal pregnancy development is lower (p = 0.002) but the levels of glucose, triglycerides, cholesterol, HDL and LDL in blood are higher Blood pressure in pregnant women with pathological pregnancy was statistically significantly higher (p < 0.001). Diagnostic criteria for the metabolic syndrome were found in 19 pregnant women with the pathological pregnancy. Statistically, in those women, a significantly higher appearance of psychological symptoms and disorders was observed in comparison to the pregnant women without metabolic syndrome (p < 0.001). The research has shown that 87.8% from all pregnant women included in this study have been hospitalized due to premature birth, hypertensive disorders, and diabetes in pregnancy, and also due to bleeding in the second and third trimester of pregnancy.
