Subtle but demonstrable movements in the expectant mother's pelvis occur during vaginal delivery in all the pelvic joints and anatomical planes of the body (sagittal, frontal, and transverse). The purpose of these movements is to gradually expand the space in the lesser pelvis via widening of the individual pelvic planes so that the newborn's head can enter the pelvic inlet, safely pass through the narrow planes of the pelvis, and through the pelvic outlet. From the point of view of biomechanics, these movements are described in literature as counternutation and nutation of the sacrum and iliac bone. The counternutation of the sacrum helps to expand the plane of the pelvic inlet. The nutation of the sacrum assists in expanding the plane of the pelvic width, height, and outlet. These physiological movements are affected by the body constitution, the state of the myofascial and skeletal systems of the mother, and furthermore, by hormonal disjunction of the connections in the expectant mother's pelvis together with the progress of the delivery mechanism itself. The main factor that determines the range of movement in the individual joints, and therefore adequate expansion of the individual pelvic planes, is the position of the mother during delivery. Engagement of active movements of the mother together with application of passive stretching of the soft tissues in the lower lumbar area and in the hip joints are both needed for maximum expansion of the individual pelvic planes and utilization of the maximum useful capacity of the mother's pelvis during delivery. These movements help invoke the abduction forces on muscles, tendons, and ligaments in the pelvis that lead to the optimum setting of the joints during which delivery movements happen. The specific movements in the pelvic joints predetermine whether nutation or counternutation is possible, and therefore if the newborn's head can progress to the pelvic inlet or pass through the narrow and wide pelvic planes, and the pelvic outlet. The knowledge of these biomechanical principles and movements in the pelvis during delivery enables obstetricians and midwives to understand how the movements in the hip joints of the expectant mother can positively impact the spatial ratios in the lesser pelvis, and how to support further progress in the event of non-progressive labour.

Objective: To compare cervical stroma in advanced cervical cancer with the control group; to compare, in the pre-treatment period, hemogram parameters in patients with advanced cervical cancer with the same parameters as the control group; and to verify if there is an association of stromal markers with prognostic factors in cervical cancer.

Materials and methods: We prospectively evaluated 16 patients diagnosed with advanced invasive cervical cancer. A control group of 22 patients was used (uterine leiomyoma). Immunohistochemistry was performed to verify the stromal immunostaining of alpha-smooth muscle actin (SMA) and fibroblast activation protein alpha (FAP). Immunostainings and hemogram parameters were compared using Fisher's exact and Mann-Whitney Test, respectively.

Results: Strong FAP immunostaining was more frequent in patients with cervical cancer when compared with patients with leiomyoma (P = 0.0002). Regarding SMA, strong immunostaining was also found more in the group of cancer patients compared to the control group (P < 0.00001). The neutrophil-lymphocyte ratio (NLR) values were higher in the cancer patient group compared to the control group (P = 0.0019). There was no association of the parameters studied with prognostic factors.

Conclusions: Strong FAP and SMA immunostaining was found more in patients with cervical cancer when compared to the control group. NLR values were also higher in cervical cancer.

Abruptio placenta can be a catastrophic event with a high association with adverse maternal and fetal outcomes. We present a case of massive abruptio placenta occurring in a young asymptomatic mother at 30 weeks' gestation. Although electronic fetal monitoring and ultrasound allowed a prompt diagnosis of an 8 × 5 cm retroplacental hematoma, the fetus died at the time of emergency cesarean section. The fetus was intubated, but could not be resuscitated. Histologic examination of the placenta documented thinning and stacked hypercapillarized villi, with syncytial buds and foci of fibrinoid necrosis in the presence of hyaline streaks on both the maternal and fetal sides.

Objective: This paper aims to analyze the factors that can influence the method of childbirth in women with multiple pregnancies.

Materials and methods: Retrospective analysis of selected parameters in women with multiple pregnancies who gave birth at the 2nd Clinic of Gynecology and Obstetrics of the Faculty of Medicine (FM), Comenius University (CU) and University Hospital (UH) Bratislava in the years 2010-2022.

Results: Between 2010 and 2022, at the 2nd Clinic of Gynecology and Obstetrics of the FM CU and UH in Bratislava, 1.13% of births were multiple pregnancies. After statistical data processing, primiparity appeared statistically significant as a risk of acute caesarean section (C-section); multiparous women had a higher probability to give birth vaginally. Since 2017, the clinic has had a decreasing trend in the number of caesarean sections. Women with an acute caesarean section, in turn had on average a lower pH of both fetuses compared to vaginal delivery. However, the incidence of asphyxia in fetuses was not statistically significantly different. We found no risk factor increasing the likelihood of acute caesarean section for fetus B in twins.

Conclusion: Multiple pregnancy has a higher morbidity not only for the woman but also for the fetuses. The incidence of multiple pregnancies is influenced by assisted reproduction. Delivery method depends on various factors such as chorionicity, fetal presentation, and history of a previous caesarean section.

Background: Vaginal atresia (VA) is a rare female genital tract malformation characterized by the absence or incomplete development of the vagina, often leading to cyclic abdominal pain and menstrual blood retention in adolescent patients. Vaginal atresia is often accompanied by multiple organ malformations. The condition poses significant challenges in diagnosis and management, requiring a multidisciplinary approach.

Case description: Herein, we report a case of type I congenital VA in a 13-year-old female presenting with congenital biliary atresia and urinary system malformation. Upon initial evaluation, the patient exhibited VA incision and laparoscopic excision of a left ovarian cyst under general anesthesia. By the 2-month follow-up, the patient reported normal menstrual flow without accompanying abdominal pain.

Conclusion: This case underscores the complexity of type I congenital VA concurrent with multiple organ malformations. Timely identification and proper management strategies are crucial for securing the best possible patient outcomes. Further research is warranted to elucidate the underlying mechanisms and improve treatment modalities for such cases.

Objective: Copeptin is a stable fragment of vasopressin. Copeptin levels have been found to reflect the degree of endothelial stress in various conditions, including acute coronary syndrome. Copeptin may be a bio marker for endothelial stress during pregnancy. However, there is still a lack of understanding of its dynamics and levels throughout pregnancy. This study aims to describe intra-individual and longitudinal changes in copeptin levels at 30th and 36th gestational weeks in healthy pregnant women with uncomplicated pregnancy and delivery and to establish specific reference ranges.

Methods: A total of 125 pregnant women with uncomplicated pregnancy and delivery were included. These women were monitored throughout their pregnancy and gave birth at the Department of Obstetrics and Gynecology Olomouc University Hospital. The blood was taken at ~30 and ~36 gestational weeks. Serum copeptin levels were measured using a Kryptor Compact PLUS analyzer. For statistics, we used R software and the "referenceRanges" package.

Results: It was found that serum levels of copeptin were significantly higher in the 36th week group than in the 30th week group (P < 0.05). Cook's distance was used to eliminate outliers. The 30th week median was 3.377 pmol/l, reference range = 1.343-7.829 pmol/l, and the 36 week was median 4.735 pmol/l and reference range = 2.06-13.2 pmol/l. In the 36th week reference range, the median was higher than in healthy, non-pregnant women (P < 0.05). Copeptin values can exceed 10 pmol/l, particularly after the 36th week. In the 3rd trimester, this value may indicate cardiovascular and endothelial overload.

Conclusion: Copeptin levels were found to vary significantly depending on gestational week. The proposed reference ranges take into account the increased secretion of vasopressin in pregnancy. The existence of specific upper reference limits represents a potential advantage in detecting pregnant women prone to hypertensive disease in the 3rd trimester.

Objective: To present a case of acute haemorrhagic stroke during 3rd trimester of pregnancy and to describe management and successful delivery of healthy baby.

Case report: Haemorrhagic stroke is responsible for significant morbidity and mortality. Prognosis can be improved only by urgent diagnosis and care. We report a case of pregnant woman at 37th week of pregnancy with acute haemorrhagic stroke of unknown etiology with clinical appearance of thunderclap headaches and overall disorientation. We describe diagnostic approach and a successful management followed by further differential diagnosis and treatment. The foetus was delivered by acute caesarean section at 37th week of pregnancy.

Conclusion: Occurrence of haemorrhagic stroke in pregnancy is rare. There are no specific guidelines that recommend the time and mode of delivery; therefore, each case is assessed individually.

The human placenta serves as a vital barrier between the mother and the developing fetus during pregnancy. A defect in the early development of the placenta is associated with severe pregnancy disorders. Despite its complex development, various molecular processes control placental development, and the specialization of trophoblast cells is still not fully understood. One primary obstacle is the lack of suitable cell model systems. Traditional two-dimensional (2D) cell cultures fail to mimic in vivo conditions and do not capture the intricate intercellular interactions vital for studying placental development. However, three-dimensional (3D) organoid models derived from stem cells that replicate natural cell organization and architecture have greatly improved our understanding of trophoblast behavior and its medicinal applications. Organoids with relevant phenotypes provide a valuable platform to model both placental physiology and pathology, including the modeling of placental disorders. They hold great promise for personalized medicine, improved diagnostics, and the evaluation of pharmaceutical drug efficacy and safety. This article provides a concise overview of trophoblast stem cells, trophoblast invasion, and the evolving role of organoids in gynecology.

Estrogens are key hormones that play a vital role in the physiology of the reproductive system in women. However, their therapeutic use in hormonal treatment, contraception, and the treatment of hormone-dependent diseases may be associated with a number of side effects, especially on the liver. This article focuses on the mechanisms of action of estrogens and their potential hepatotoxic effects, as well as risk factors and possible differences between representatives.

Objective: To compare the subjective and objective results of laparoscopic sacrocolpopexy (LSC) with and without the introduction of a vaginal packing one year after surgery. Methodology: This is a retrospective cohort study of 125 women after laparoscopic sacrocolpopexy operated on in 2013-2016 with complete annual follow-up. Patients with a total hysterectomy were excluded from the study. Basic patient characteristics, preoperative POP-Q and surgery data were collected. The subjective outcome of the surgery was assessed using the PGI-I (patient global impression of improvement). The anatomic outcome of the surgery was evaluated using the composite definition of surgical failure based on POP-Q (Ba ≥ -1, C ≥ -3, Bp ≥ -1). Patients were divided into two groups according to whether or not they had vaginal packing after surgery. Statistical analysis was performed using c2, Wilcoxon and Fischer test according to the distribution of normality. Results: A total of 125 women were enrolled in the study; 48 (38.4%) after LSC, 58 (46.4%) with concomitant supracervical hysterectomy and 19 (15.2%) after sacrohysterocolpopexy. Vaginal packing was introduced for 24-48 hours after surgery in 86 (68.8%) women. The groups did not differ in age, body mass index, smoking or preoperative pelvic organ prolapse quantification system. We did not observe statistically significant differences in PGI-I first year after surgery. The difference in anatomic surgical failure did not reach statistical significance, although more failures were observed in the group without packing (12.8 vs. 3.5%; P = 0.09). The mean C-point value one year after surgery was lower in the non-tamponade group (-7 vs. -7.5; P < 0.009). No mesh extrusion or serious complications were recorded in the monitored group. Conclusion: Vaginal packing after LSC probably does not affect patient satisfaction after surgery, however, it may be associated with better anatomical outcome one year after the surgery. The results of the study must be confirmed by a more detailed prospective evaluation.
