Objectives: The aim of this study was to evaluate the accuracy of IOTA Simple Rules (SR), IOTA ADNEX model, Risk of Malignancy Index (RMI), and subjective assessment (SA) which is used for adnexal mass assessment in our institution. Design: This is a prospective observational study. Participants/Materials, Setting, Methods: We included patients with at least one adnexal mass who needed elective surgical evaluation based on clinical and laboratory findings. Patients admitted to Clinic for Gynecology and Obstetrics, University Clinical Center of Serbia, were recruited for the study between January 2019 and June 2021. Level II ultrasonographers performed a gray scale and Doppler exam for each patient. Preoperative classification of adnexal masses (benign or malignant) was performed by SA, the International Ovarian Analysis Group (IOTA) SR, IOTA ADNEX model, and Risk of Malignancy Index (RMI). Postoperatively obtained histological findings were used as a reference. Results: During the study period, we enrolled 179 premenopausal and 217 postmenopausal patients, representing 396 patients in our sample. Prevalence of malignant disease in pre- and postmenopausal groups was 16.2% (29/179) and 41% (89/217), respectively. Malignant disease was diagnosed in 29.8% (118/396) of patients. SA achieved the highest discrimination accuracy between benign and malignant tumors (area under the curve [AUC] of 0.928, 95% CI [0.898-0.952]). For SA, the overall diagnostic accuracy, sensitivity, specificity, positive likelihood ratio (LR+), and negative likelihood ratio (LR-) were 91.4%, 88.1%, 92.8%, 12.25, and 0.13. The AUC for Simple Rules with subjective assessment in inconclusive cases (SR + SA) was 0.912 (95% CI [0.880-0.938]). Regarding SR + SA, diagnostic accuracy, sensitivity, specificity, LR+, and LR- were 92.4%, 88.1%, 94.2%, 15.31, and 0.13. The ADNEX model had the AUC of 0.914 (95% CI [0.882-0.940]). Binary classification using the ADNEX model at a cut-off value of 10% for malignancy had the sensitivity, specificity, LR+ and LR- of 92.4%, 73.0%, 3.42, and 0.10. This resulted in the lowest overall accuracy of 78.8%. The AUC for RMI was 0.854 (95% CI [0.815-0.887]), with overall accuracy, sensitivity, specificity, LR+ and LR- of 82.3%, 73.7%, 86.0%, 5.26, and 0.31. There was no difference in the AUCs of the SA and IOTA models for the whole group, premenopausal, and postmenopausal groups. RMI performed worse compared to SA and the IOTA models. The ADNEX model achieved the highest accuracy at the cut-off value of 35%. Limitations: The data generalizability is limited by a single institution-dependent sampling. Conclusions: The IOTA SR and ADNEX model were reliable and comparable with the SA and performed better than the RMI. The IOTA SR model offers the potential for immediate and reliable diagnosis, even in the hands of less experienced ultrasonographers. Both IOTA models studied can be a valuable adjunct to a clinician's decision-making process. © 2023 S. Karger AG, Basel. All rights reserved.

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. © 2025 by the authors.

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. © 2015 by De Gruyter 2015.

Endocrine-disrupting chemicals are significant contributors to various detrimental conditions, mechanistically disrupting the endocrine system and causing adverse health effects. Mounting evidence suggests they can induce multigenerational and transgenerational effects, yet awareness among individuals remain insufficient. This study aimed to assess the knowledge, attitudes and ways of informing mothers in Serbia about endocrine disruptors based on information from 190 women in Serbia. The research was conducted using a survey consisting of multiple-choice questions comprising: The first part aimed to collect sociodemographic data, the second part related to knowledge and attitudes about endocrine disruptors, and the third part focused on the sources of information about endocrine disruptors. Cronbach’s alpha was used to check for scale reliability, and Pearson correlation was used to test the relations between interval variables. ANOVA was employed to test for group differences. The results indicated that mothers in Serbia do not have adequate knowledge about endocrine disruptors (potential sources, categories of substances and alternatives) nor confidence in their ability to mitigate exposure to endocrine disruptors. Also, the estimation of the health risks of exposure to endocrine disruptors was perceived as high, and the mothers thought that they should get additional information about endocrine disruptors before pregnancy. Although with several limitations (i.e. mothers were recruited among those with higher education and mainly from urban areas), the study results highlight the necessity for enhanced maternal education in Serbia regarding endocrine disruptors. Health professionals are deemed most suitable for providing this education, given the respondents’ high level of trust in them. © 2025 the author(s)
