Introduction: Neural tube defects (NTDs) are a group of heterogeneous congenital anomalies of the central nervous system (CNS). Acrania is a non-NTD congenital disorder related to the CNS. It can transform into anencephaly through the acrania–exencephaly–anencephaly sequence (AEAS). In AEAS, the cerebral tissue is not protected and is gradually destroyed due to exposure to the harmful effect of amniotic fluid and mechanical injuries. These lead to exencephaly and then into anencephaly. In contrast to primary anencephaly (NTDs), this type of anencephaly authors suggests calling secondary anencephaly. Objective: Analysis of the known prenatal ultrasonography (US) signs associated with AEAS. Simultaneously, the authors propose a new sign in the differentiation of acrania from exencephaly and anencephaly, called the “beret” sign. Methods: It is a two-centre retrospective observational study. As part of the study, 4060 US scans were analyzed. Results: In 10 cases, the absence of calvarium was diagnosed, allowing recognition of either AEAS stages or primary anencephaly. In 5 cases, cerebral structures were enclosed by an inertial rippled thin membrane, with a smooth outer contour. Between the described membrane and the brain structures, a thin anechoic space corresponding to cerebrospinal fluid was observed. This sign was defined as the “beret” sign. In these cases, acrania was diagnosed. In three cases calvarium was missing. The brain structures had an irregular appearance, did not wave and remained motionless. The outer contour was unequal as if divided into lobes. Amniotic fluid was anechoic. Exencephaly was diagnosed in these cases. In two cases calvarium, brain structures, and meninges were missing. The “frog eyes” sign and slightly echogenic amniotic fluid were visible. In this case, anencephaly was diagnosed. Conclusions: The “beret” sign seems to be a promising tool in the diagnosis of acrania. Furthermore, echogenicity of amniotic fluid could be useful during differentiation between primary and secondary anencephaly.

Uterine fibroids are benign tumors that arise from the smooth muscle tissue of the uterus and are the most common tumors in women. Due to their high prevalence, costs for the health care system and the substantial impact on women’s quality of life, they are a significant public health concern. Previous literature on the impact of diet on the occurrence, growth and symptoms of fibroids is limited. Recently, many papers have been written on this topic. A scoping review of PubMed and Cochrane databases was performed using the following keywords: uterine fibroids, antioxidants, diet, diet, vegetarian, vegetables, fruits, meat and soy foods, dairy products, tea, vitamin D, vitamin C, ascorbic acid. Preliminary research has shown a beneficial effect of vegetable and fruit consumption on the occurrence of fibroids. A relationship between hypovitaminosis D and an increased risk of fibroids has also been demonstrated. Studies on epigallocatechin gallate showed its apoptosis-promoting and antifibrinolytic effect in fibroid cells. Initial results are promising, but further randomized trials are needed to draw firm conclusions about the effects of diet and nutrients on uterine fibroids.

Uterine fibroids, benign tumors originating from uterine smooth muscle cells, vary in prevalence depending on patient ethnicity, hormonal exposure, and genetics. Due to their high incidence, these neoplasms pose a significant burden on healthcare systems. Current treatment strategies range from routine monitoring in asymptomatic cases to surgical procedures such as myomectomy or hysterectomy in symptomatic patients, with an increasing trend toward uterus -preserving or non -surgical alternatives. This review examines the existing medical treatments for uterine fibroids and delves into the potential of emerging therapies. A scoping review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta -Analyses extension for Scoping Reviews. Medical therapies are divided into hormonal and non -hormonal treatments; however, long-term, safe, and effective treatments in the treatment of uterine fibroids are limited. In addition to established therapies, there is an increasing number of studies investigating the effect of substances such as vitamin D or green tea extract on uterine fibroids. Some studies investigate acupuncture as a possible alternative therapy. While existing treatments offer symptomatic relief and preparation for surgery, our findings point to a significant need for further research into long-term solutions, especially owing to recent limitations in the use of ulipristal acetate due to risk of liver damage. Initial studies involving vitamin D and epigallocatechin gallate are encouraging; however, additional research is required to establish definitive therapeutic roles.

Umbilical cord mesenchymal stromal cells (UC-MSCs) are a key element of regenerative medicine due to their ability to secrete growth factors that stimulate proliferation and angiogenesis, and modulate the inflammatory response. Despite their widespread use, the influence of the perinatal microenvironment on their biological properties remains poorly understood. The aim of this study was to assess the influence of pH and blood gas parameters in umbilical cord blood on the global transcriptomic profile of UC-MSCs and to analyze the correlation between the metabolic status of the newborn and the expression of key trophic factors: EGF, FGF2, FGFR1, FGFR3, GDNF, HGF, IGF1, NES, NGF, and PGF. Methods: The study was conducted in two stages. In the first phase, transcriptomic screening was performed using Affymetrix HuGene 2.0 ST microarray on cells isolated from three environmental groups defined by cord blood pH: acidic (pH < 7.35), physiological (7.35–7.39), and alkaline (pH ≥ 7.4). In the second phase, the results were validated using qPCR on an expanded study group (N = 50). Gene expression levels (RQ) were related to blood gas parameters (pH, pCO₂, pO₂, cHCO₃) and the presence of clinical features of threatened neonatal asphyxia. Results: Microarray analysis revealed that environmental pH acts as a molecular phenotypic switch. Under low pH conditions (<7.35), a shift in cell profile from proliferative to structural–migratory was observed. Significant overexpression of genes responsible for extracellular matrix (ECM) organization and adhesion (e.g., COMP, DCN, LUM, FMOD) was observed, while pathways related to cell cycle and cell division (↓CDK1, AURKA, TOP2A) were downregulated. qPCR validation confirmed these observations, demonstrating a strong positive correlation between blood pH and the expression of regenerative mediators: FGFR1 (r = 0.28), EGF (r = 0.30), NGF (r = 0.39), and IGF1 (r = 0.30). A negative correlation was also found between carbon dioxide pressure (pCO₂) and the expression of NGF, FGFR1, and EGF. A significant clinical finding was that in newborns diagnosed with threatened asphyxia, EGF, FGFR1, and NGF gene expression was significantly reduced, indicating impaired trophic potential of the cells in response to metabolic stress. Conclusions: These results indicate that cord blood gas parameters are critical regulators of the genetic activity of UC-MSCs. Metabolic and respiratory acidosis not only inhibit the cells’ proliferative potential but also force them into a matrix remodeling mode, permanently modifying their transcriptomic profile. This suggests that the neonatal acid–base status may serve as an objective indicator of the “biological quality” of isolated stromal cells, which has significant implications for their future applications in cell therapies.

Objectives: To assess long-term efficacy and safety of uterine artery embolization for symptomatic uterine fibroids. Material and methods: This retrospective cohort study included women undergoing uterine artery embolization for symptomatic fibroids from 2012 to 2023. A validated questionnaire assessed symptoms (e.g., heavy menstrual bleeding, pelvic pain) pre- and post- uterine artery embolization. Data on fibroid characteristics, follow-up duration, menopause status, and complications were collected. Patients were stratified into follow-up terciles. Statistical analyses included Wilcoxon signed-rank tests, linear regression with menopause adjustment, and Spearman correlations tests (p < 0.05). Results: Uterine artery embolization significantly reduced symptoms, particularly bleeding-related complaints, with sustained efficacy across short-, mid-, and long-term follow-up, even after menopause adjustment. Menopause enhanced symptom relief. No correlations were found between symptom reduction and age, fibroid size, or prior treatment. Complications, mostly minor, occurred in a notable proportion, with rare major events. A small subset achieved successful pregnancies post-embolization. Conclusions: Uterine artery embolization is an effective, minimally invasive treatment for fibroid-related symptoms, with sustained benefits over time; menopause significantly predicts greater symptom improvement.
