Uterine fibroids (leiomyomas and myomas) are the most common benign gynecological condition in patients presenting with abnormal uterine bleeding, pelvic masses causing pressure or pain, infertility and obstetric complications. Almost a third of women with fibroids need treatment due to symptoms. Objectives: In this review we present all currently available treatment modalities for uterine fibroids. Methods: An extensive search for the available data regarding surgical, medical and other treatment options for uterine fibroids was conducted. Review: Nowadays, treatment for fibroids is intended to control symptoms while preserving future fertility. The choice of treatment depends on the patient’s age and fertility and the number, size and location of the fibroids. Current management strategies mainly involve surgical interventions (hysterectomy and myomectomy hysteroscopy, laparoscopy or laparotomy). Other surgical and non-surgical minimally invasive techniques include interventions performed under radiologic or ultrasound guidance (uterine artery embolization and occlusion, myolysis, magnetic resonance-guided focused ultrasound surgery, radiofrequency ablation of fibroids and endometrial ablation). Medical treatment options for fibroids are still restricted and available medications (progestogens, combined oral contraceptives andgonadotropin-releasing hormone agonists and antagonists) are generally used for short-term treatment of fibroid-induced bleeding. Recently, it was shown that SPRMs could be administered intermittently long-term with good results on bleeding and fibroid size reduction. Novel medical treatments are still under investigation but with promising results. Conclusions: Treatment of fibroids must be individualized based on the presence and severity of symptoms and the patient’s desire for definitive treatment or fertility preservation.

Background: Polycystic ovary syndrome (PCOS) is a multisystem reproductive–metabolic disorder and the most common endocrine cause of infertility. The objective of our study was to determine the influence of myo-inositol (MI) on insulin resistance (IR), menstrual cycle regularity, and hyperandrogenism in women suffering from PCOS with normal BMI and diagnosed IR. Methods: We performed a prospective randomized controlled trial (RCT) that included 60 participants with PCOS who had IR and a normal BMI. Two groups were formed. A group of thirty patients received MI, and thirty patients in the control group received metformin (MET). Results: A statistically significant reduction in the area under the curve (AUC) of insulin values during the oral glucose tolerance test (OGTT) was recorded in both examined groups after the applied therapy with MI and MET. The regularity of the menstrual cycle in both groups was improved in >90% of patients. A statistically significant decrease in androgenic hormones (testosterone, SHBG, free androgen index—FAI, androstenedione) was recorded in both groups and did not differ between the groups. Conclusions: Both MI and MET can be considered very effective in the regulation of IR, menstrual cycle irregularities, and hyperandrogenism in women with PCOS.

Background/Objectives: Polycystic Ovary Syndrome (PCOS), as a multifactorial chronic disease, can cause heterogeneous metabolic, physical, and psychological disorders as well as infertility in both obese and non-obese patients. Therefore, this review aimed to present differences in pathophysiology, clinical presentation, and therapy in obese and non-obese patients with PCOS. Methods: A non-systematic review was conducted by searching papers published in English from 2010 to 2024 in MEDLINE. Results: Obesity in PCOS significantly contributes to IR and worsens metabolic dysfunction. Lifestyle modifications, including a balanced diet and regular exercise, are the first line of treatment. Pharmacological therapies, such as metformin, GLP-1 receptor agonists, myoinositol, and resveratrol, are used to improve insulin sensitivity, regulate the hormonal milieu, and reduce hyperandrogenism. Metformin is widely used to improve glucose metabolism and reduce androgen levels, while myoinositol is effective in promoting ovarian function. GLP-1 receptor agonists and resveratrol improve metabolic and reproductive outcomes. For patients with severe obesity, bariatric surgery offers substantial improvements in body composition, metabolic function, and fertility. Combination therapies, such as metformin and GLP-1 receptor agonists, provide comprehensive treatment for both reproductive and metabolic aspects of PCOS. Conclusions: The first-line treatment for PCOS is a lifestyle-modifying strategy. PCOS patients with insulin resistance and obesity would mostly benefit from combination therapy with metformin and GLP-1 receptor agonists.

Introduction: Intrauterine fetal death (IUFD) is defined as death of the fetus after the 20th week of gestation. Despite regular monitoring the incidence of IUFD remains high. This study aims to assess the incidence and maternal conditions associated with IUFD over term pregnancies in a twelve-year period. Materials and Methods: A retrospective descriptive study was conducted on a population of women in whom IUFD was diagnosed in a term pregnancy during the period from January 2010 to December 2022. The study was at the Clinic for Obstetrics and Gynecology, University Clinic Centre of Serbia. The analyses included the number of deliveries, live births, and stillbirths, as well as maternal, fetal, and placental conditions associated with the risk of IUDF. The statistical analysis involved descriptive statistical methods and one sample proportion. Results: The average age of the patients was 30 years. Most patients had secondary and higher education, and 70% of patients had regular pregnancy monitoring; 53.33% were primiparous and pregnancies occurred spontaneously. IUFD mainly occurred in the 39th week of gestation. In total, 38.3% had one to two associated diseases, 5% more than three, and 58.33% were healthy. Recurrence of IUFD was reported by 10% of patients, while 8.33% had a history of spontaneous abortion. Over 80% of placental histopathological findings indicated some pathology (e.g., infarction, infections, placental abruption). Conclusions: The most significant risk factors for IUFD in term pregnancies in our population during the study period were hypertensive syndrome in pregnancy, obesity and gestational diabetes. Pathological findings on the placenta were more common in our study group than is usually reported with infractions of placental tissue being the most common, even in healthy women.

Background and Objectives: Gestational diabetes mellitus (GDM) is a major public health concern associated with adverse maternal and neonatal outcomes. It was found that even physiological pregnancy is followed by a significant shift in serum lipid profile, and even more pronounced in GDM pregnancies. We aimed to comprehensively assess lipid parameters among pregnant women with and without GDM. Materials and Methods: A systematic review, covering PubMed, WoS, and SCOPUS until 23 July 2024, with meta-analysis and meta-regression, was conducted, comprising studies measuring TG, TC, LDL-C, HDL-C, VLDL-C, and TG/HDL ratio in pregnant women diagnosed with GDM, and those with normal glucose tolerance. The overall effect size measure was the SMD. NOS and JADAD scales were used for quality assessment, I2 statistics for heterogeneity evaluation, and funnel plots for publication bias inspection. Results: A total of 457 studies were included in the qualitative analysis, and 74, 277, and 122 studies were included in the quantitative analysis for the 1st 2nd, and 3rd trimester, respectively. TG and TG/HDL levels were significantly elevated in all three trimesters (TG: SMD = 0.61, 0.57, and 0.48, p < 0.001 for all, and TG/HDL: SMD = 0.44, 0.66, and 0.49; p < 0.001 for all), while TC and LDL-C levels showed significant increases in the 1st and 2nd trimesters (TC: SMD = 0.38, 0.27, p < 0.001 for both, LDL-C: SMD = 0.33, 0.20, p < 0.001 for both), in pregnant women with GDM compared to those without the condition. Conclusions: GDM is associated with significant lipid abnormalities, particularly elevated TG and decreased HDL-C levels. These lipid changes are most pronounced in the first and second trimesters, highlighting the importance of early detection and management.

Background and Objectives: The prevalence of depressive symptoms during pregnancy is about 20%, and 10–15% in the postpartum period. Suicide is a worrying cause of death among women in these periods. Although ICD-10 lacks specific definitions for perinatal depression (it is planned in ICD-11), the DSM-5 defines it. Various etiological factors and treatment options are being investigated. This study aimed to examine potential etiological factors in order to contribute to potential preventive and therapeutic approaches. Material and Methods: A prospective study at the Clinic for Gynecology and Obstetrics, University Clinical Center of Serbia, from October 2023 to January 2024 was conducted. Two hundred and five healthy women were surveyed before giving birth (37+ gestational weeks) and 2 weeks and 2 months after childbirth. The following factors were examined: sociodemographic, psychological, and obstetric (using a specially designed questionnaire); relationship quality (DAS-32); and depression, anxiety, and stress symptoms (EPDS; DASS-21). Results: Depression frequency was 26.3% before childbirth, 20% in the second week, and 21.9% in the second month after delivery. DASS-21 test results showed a statistically significant correlation before delivery and two weeks postpartum (p = 0.02). Factors that are significantly associated with the presence of depressive symptoms include the following: before childbirth—miscarriages (p < 0.01); in the second week after childbirth—personal experiences of a difficult birth (p < 0.01), cesarean delivery instead of planned vaginal delivery (p = 0.03), and application of epidural anesthesia (p = 0.04); and in the second month after childbirth—satisfaction with financial status (p = 0.035). Relationship quality is significantly correlated with DASS-21 test results before childbirth, in the second week, and in the second month after childbirth (p < 0.01), and it is significantly different in women with and without depressive symptoms (before childbirth, in the second week, and in the second month after childbirth, p < 0.01). Conclusions: There are risk factors that can be addressed preventively and therapeutically during pregnancy and in labor. This could be achieved through psychotherapy, partner support, and appropriate management of labor.
