The aim of this study was to examine the differences in pregnancy complications, delivery characteristics, and neonatal outcomes between women with type 1 diabetes mellitus (T1DM), type 2 diabetes mellitus (T2DM), and gestational diabetes mellitus (GDM). This study included all pregnant women with diabetes in pregnancy in Belgrade, Serbia, between 2010 and 2020. The total sample consisted of 6737 patients. In total, 1318 (19.6%) patients had T1DM, 138 (2.0%) had T2DM, and 5281 patients (78.4%) had GDM. Multivariate logistic regression with the type of diabetes as an outcome variable showed that patients with T1DM had a lower likelihood of vaginal delivery (OR: 0.73, 95% CI: 0.64–0.83), gestational hypertension (OR: 0.47, 95% CI: 0.36–0.62), higher likelihood of chronic hypertension (OR: 1.88, 95% CI: 1.55–2.29),and a higher likelihood ofgestational age at delivery before 37 weeks (OR: 1.38, 95% CI: 1.18–1.63) compared to women with GDM. Multivariate logistic regression showed that patients with T2DM had a lower likelihood ofgestational hypertension compared to women with GDM (OR: 0.37, 95% CI: 0.15–0.92).Our results indicate that the highest percentage of diabetes in pregnancy is GDM, and the existence of differences in pregnancy complications, childbirth characteristics, and neonatal outcomes are predominantly between women with GDM and women with T1DM.

Aims: The study aim was to evaluate pregnancy outcomes in patients with antiphospholipid syndrome (APS) and to determine which clinical parameters present risk factors for adverse pregnancy outcomes in these patients. Methods: The study included 55 patients with APS treated at the Clinic for Ob/Gyn, Clinical Center of Serbia, from 2006 to 2012. The control group consisted of 55 healthy pregnant women. Data regarding previous pregnancies and conception method were registered. Immunological and laboratory tests were performed. Pregnancy outcomes, including miscarriage, intrauterine fetal death, hypertensive disorders, diabetes mellitus, phlebothrombosis, fetal growth restriction, premature delivery, delivery method, perinatal asphyxia, respiratory distress syndrome, intraventricular hemorrhage, and necrotizing enterocolitis were followed. Results: The premature delivery rate in APS patients was 31.8%, and pregnancy loss was 18.2%. Significantly more patients with APS had thrombocytopenia, pregnancy losses, intrauterine growth restriction, and perinatal asphyxia compared with the control group. More miscarriages, preterm delivery, lower birth weight, preeclampsia, and IgM anticardiolipin antibody levels significantly correlated with adverse pregnancy outcomes. Although rare, respiratory distress syndrome can also worsen neonatal health status. According to ROC analysis, previous miscarriages correctly explained 66.3% of adverse pregnancy outcome cases. We generated four equations of adverse pregnancy outcome risk factors. Conclusions: The most important prognostic factor for pregnancy outcome in APS patients is the number of previous miscarriages. Using appropriate current therapeutic protocol can enable live birth of a healthy newborn in most cases.

The aim of this study was to analyze the trends in diabetes in pregnancy in Belgrade, Serbia for the period of the past decade and forecast the number of women with pre-gestational diabetes for the years 2030 and 2050. The study included the data on all pregnant women with diabetes from the registry of the deliveries in Belgrade, by the City Institute of Public Health of Belgrade, Serbia for the period between 2010 and 2020 and the published data on the deliveries on the territory of Belgrade. During the examined period the total number of live births in Belgrade was 196,987, and the prevalence of diabetes in pregnancy was 3.4%, with the total prevalence of pre-gestational diabetes of 0.7% and overall prevalence of GDM of 2.7%. The average age of women in our study was significantly lower in 2010 compared to 2020. The forecasted prevalence of pre-gestational diabetes among all pregnant women for 2030 is 2% and 4% for 2050 in our cohort. Our study showed that the prevalence of pre-gestational diabetes has increased both among all pregnant women and among women with diabetes in pregnancy in the past decade in Belgrade, Serbia and that it is expected to increase further in the next decades and to further double by 2050.

Objective: To assess which obstetrical characteristics and treatment improved outcomes and prognosis of pregnant women with malignancy. Methods: A prospective study, undertaken between 2005 and 2014, involving 35 pregnant women who were diagnosed with malignant tumors during pregnancy. Patients were followed-up for 1 year after delivery. The pregnancy course and outcome and parameters that could influence the condition of mother and fetus were evaluated. Results: Most malignancies were hematological, diagnosed in the second trimester and treated with combined therapy (surgery/adjuvant) after pregnancy. Most fetuses were in good state throughout pregnancy, but were delivered by caesarean section (CS) before term. Adjuvant therapy during pregnancy mostly caused transitory deterioration of fetal conditions. The majority of both mothers and infants were in a good state 12 months postpartum, although numerous mothers were still ill and on therapy. Surviving pregnancy and preventing tumors progression during pregnancy were the best predictors of mothers’ future condition (P=0.022). High birthweight and term delivery were the most important factors for good outcome of the infants (P=0.001). Conclusions: If the tumor is not progressing, pregnancy should be continued as long as possible to obtain adequate birthweight of the infant. Second trimester surgery is safe, while other therapies should preferably be applied after delivery.

The estimated incidence of melanoma complicating pregnancy has ranged from 0.1 to 2.8 per 1,000 pregnancies. Here the Authors present a case of a 40-year-old pregnant woman, who was admitted to the Clinic of Obstetrics and Gynaecology in 26 weeks of gestation, with diagnosis of melanoma and suspected with fetal anomaly, as possible bowel obstruction, and polyhydraminos. The melanoma was asported with a wide local excision under local anesthesia. Histological evaluation revealed melanoma Stage Ib (Clark IV, Breslow thickness 1.2 mm, pT2a). Lymph node sonography of neck, axilla, inguinum, abdomen, and pelvis as well as chest radiography did not demonstrate any evidence of metastatic disease. After vaginal delivery at 37 weeks of gestation, the female preterm hypotrophic newborn was transferred to the Institute for Neonatology and underwent resection of duodenojejunal atresia with tapering duodenoplasty and duodenojejunal termino-terminal anastomoses due to intestinal obstruction. No evidence of the melanoma was found in the placenta. Two years later the child was healthy and the mother was disease-free.

Background/Objectives: Due to the rarity and histological heterogeneity of non-epithelial ovarian cancers (NEOCs), monitoring their reproductive and oncological outcomes is challenging. Therefore, this study aimed to investigate the oncological and reproductive outcomes of patients with NEOCs treated with fertility-sparing surgery over the past 10 years at our tertiary referral university clinic. Methods: This retrospective study included all the NEOC patients diagnosed and treated with fertility-sparing surgery from 2010 to 2019. The patient demographic and clinical characteristics; data regarding the treatment andthe clinical, laboratory, and imaging findings during follow-up; and disease recurrences were recorded. In this study, the recurrence-free survival and the overall survival were the oncological outcomes. The reproductive outcomes were assessed as attempting and achieving pregnancy. Results: This study included 39 patients. The most frequent NEOCs were granulosa cell tumors (53.8%). The majority of the tumors were in the IA or IC1 stage. The initial therapy was generally a unilateral salpingo-oophorectomy (30.8%). Adjuvant chemotherapy was received by 48.7% of the patients. An NEOC recurrence was registered in 25.6% of the patients, mostly during the first two postoperative years. The recurrence-free survival was 76.92%. A regression analysis showed that amore advanced stage of NEOC was the most important predictor of disease recurrence. The overall survival rate was 87.2%, with a mean time to an adverse outcome of 23.01 +/−10.68 months. The regression analysis showed that better survival depended mostly on not having disease recurrence. After treatment, ten patients tried to conceive and seven succeeded. All the children were in good condition upon birth. Conclusions: Fertility-sparing treatment for NEOCs was proven as a safe and successful option in terms of both oncological and reproductive outcomes.
