AbstractSince their market launch in 2007, e-cigarettes gained popularity and were considered a relatively safe alternative to traditional cigarettes. Pregnant women and women of childbearing age in particular are increasingly turning to e-cigarettes. Little is known about the effects of prenatal exposure on the affected foetus. This paper aims to provide an overview of the current research on the effects of prenatal e-cigarette exposure on the foetus. Since studies in humans are lacking to date, this review refers only to animal and in vitro analyses. The PubMed and Web of Science databases were used for an extensive literature search. The search yielded N = 17 significant research papers. Possible sequelae resulting from prenatal exposure to traditional cigarettes were also seen in prenatal exposure to e-cigarettes. Prenatal e-cigarette exposure was found to be associated with increased DNA methylation overall, resulting in lower gene expression. This could adversely impact the development of affected children, especially in case of those genes relevant to their development. In mice, for example, this greatly reduced the cell vitality of neural and stem cells and increased cell death. Further, prenatal exposure to e-cigarettes resulted in numerous developmental disorders, such as malformations of facial morphology and lower birth weight. Moreover, in animal models the animals suffered from a deterioration of their short-term memory. Activity and cognitive flexibility increased, while anxiety behaviour decreased. It is clear that more research and especially studies of humans are needed on this issue. In addition, there is a need for more intense education of prenatal care professionals as well as women of childbearing age and during pregnancy.

AbstractVenous thromboembolism (VTE) during or after assisted reproductive technologies (ART) is predicted to rise due to the increased number of women undergoing this technique. We present data collected in the RIETE registry up to October 2016. Overall, 41 (0.6%) out of 6,718 women of childbearing age with VTE had an ART-related event. Most of them underwent autologous ART cycles; 23 had isolated deep vein thrombosis (DVT) (56.1%), 12 isolated pulmonary embolism (PE) (29.3%) and 6 simultaneous occurrence of both the events (14.6%). VTE occurred in 20 successful and 21 unsuccessful (i.e. not resulting in a clinical pregnancy) ART cycles. No recurrence was observed at 90 days. Logistic regression showed that isolated PE was significantly more frequent than DVT alone or combined with PE in unsuccessful in vitro fertilization (IVF) (odds ratio [OR]: 4.13, 95% confidence interval [CI]: 1.4–12.4), as well as in contraceptive users (OR: 2.96, 95% CI: 1.95–4.5) and in puerperium (OR: 1.96, 95% CI: 1.16–3.3). After grouping isolated PE and DVT + PE, we found that PE was significantly more frequent in women with unsuccessful IVF and higher body mass index (OR: 5.0, 95% CI: 1.2–20.7 and OR: 1.0, 95%CI: 1.0–1.1, respectively). These data document a higher risk of PE in unsuccessful cycles than in successful ones. The risk is higher than that observed during pregnancy, puerperium and contraception.

The aim of the study. Assess the importance of pregravid preparation and outcomes of pregnancy and childbirth, depending on the reproductive attitudes of women in the city of Omsk. Materials and methods. The study included 92 women who were divided into groups: group A (n=43) - women whose pregnancy was planned; group B (n=49) - women whose pregnancy occurred accidentally. Each group was divided into subgroups depending on age: from 18 to 30 and from 31 to 49 years. For each patient included in the study, a specially designed map was filled out. These patients were interviewed at the City Clinical Perinatal Center. Results. Comparative analysis revealed the relationship between the reproductive settings of women of childbearing age and the peculiarity of the course of pregnancy and childbirth in these patients. Summary. The majority of women of fertile age are married: in subgroup AA - 25 (96.2%), AB - 13 (76.5%), BA - 25 (92.6%), BB - 20 (91.0%). The predominant number of women of fertile age have one or more abortions: in subgroup AA - 12 (46.2%), AB - 6 (35.3%), in subgroups of comparison BA - 8 (29.6%), BB - 6 (27.3%). More than half of the women of fertile age surveyed have a history of untreated cervical pathology (from 40.8% to 64.7%). The course of pregnancy in women planning pregnancy in most cases proceeded without complications: in subgroup AA - 13 (50.0%), AB - 11 (64.7%). The most common cause of complicated pregnancy in women whose pregnancy occurred accidentally is the threat of spontaneous miscarriage: in subgroup BA - 15 (55.6%), BB - 16 (72.7%). The uncomplicated course of labor more often [subgroup AA - 19 (73.0%), AB - 12 (70.6%)] was observed in women whose pregnancy was planned and they were motivated to give birth to a healthy child.

Background and Objectives: Uterine fibroids develop in 25–40% of women of childbearing age; however, there are discrepancies resulting from population and socioeconomic differences. The pathogenesis of fibroids is not clear. The aim of the study was to assess the potential connection between the use of oral contraceptives and the occurrence of uterine fibroids in women of childbearing age. Materials and Methods: In this prospective, survey, case–control study, data were collected from Caucasian female patients (mean age = 30) using a questionnaire concerning the onset, duration and form of hormonal contraception, and medical and obstetrical history. The questionnaires were handed personally to hospitalized patients as well as distributed through Google forms on social media. Results: In a study group (n = 140) of patients using hormonal contraception, 37.8% of them were diagnosed with uterine fibroids, whereas among the patients not using hormonal contraception (n = 206), uterine fibroids were diagnosed in 59.6% of the patients. The most common hormonal contraception was two-component hormonal tablets used by 93.3% of the patients. Taking contraceptives was a uterine fibroids protective factor (OR = 0.4, p = 0.007). In the study group, 5.5% of the patients were pregnant and 60.42% were diagnosed with uterine fibroids (OR = 4.4, p < 0.000001). Conclusion: Contraception was found to be a protective factor for uterine fibroids among the women surveyed. The presented data confirm the theory about the hormonal dependence of uterine fibroids.

Major lignans of sesame sesamin and sesamolin are benzodioxol--substituted furofurans. Sesamol, sesaminol, its epimers, and episesamin are transformation products found in processed products. Synthetic routes to all lignans are known but only sesamol is synthesized industrially. Biosynthesis of furofuran lignans begins with the dimerization of coniferyl alcohol, followed by the formation of dioxoles, oxidation, and glycosylation. Most genes of the lignan pathway in sesame have been identified but the inheritance of lignan content is poorly understood. Health-promoting properties make lignans attractive components of functional food. Lignans enhance the efficiency of insecticides and possess antifeedant activity, but their biological function in plants remains hypothetical. In this work, extensive literature including historical texts is reviewed, controversial issues are critically examined, and errors perpetuated in literature are corrected. The following aspects are covered: chemical properties and transformations of lignans; analysis, purification, and total synthesis; occurrence in Seseamum indicum and related plants; biosynthesis and genetics; biological activities; health-promoting properties; and biological functions. Finally, the improvement of lignan content in sesame seeds by breeding and biotechnology and the potential of hairy roots for manufacturing lignans in vitro are outlined.
