Uterine fibroids (UFs) are benign tumors of the female genital tract made of the smooth muscle of the uterus. UF growth depends mostly on the influence of the steroid hormones and selected growth factors. Transforming growth factor β (TGF-βs) is a polypeptide that consists of three isoforms: TGF-β1, TGF-β2, and TGF-β3. At present, TGF-β is considered to be one of the key factors in the pathophysiology of UFs. It plays a major role in cellular migration within the tumor, stimulates tumor growth, and enhances tumor metabolism. As a consequence of various dependencies, the synthesis and release of TGF-β in a UF tumor is increased, which results in excessive extracellular matrix production and storage. High concentrations or overexpression of TGF-β mediators may be responsible for clinically symptomatic UFs. The aim of this review was to check the available evidence for the influence of the TGF-β family on UF biology. We conducted their search in PubMed of the National Library of Medicine with the use of the following selected keywords: “uterine fibroid”, “leiomyoma”, and “transforming growth factor β”. After reviewing the titles and abstracts, more than 115 full articles were evaluated. We focused on the TGF-β-related molecular aspects and their influence on the most common symptoms that are associated with UFs. Also, we described how the available data might implicate the current medical management of UFs.
IntroductionThe age of menopause is a time of many changes in the psychophysical-social functioning of women, with reduced ovarian hormonal activity and estrogen levels. The most common, troublesome symptoms of menopause age include depressive disorders, sleep disorders, sexual dysfunction, discomfort associated with muscle pain, joint aches, osteoporosis and characteristic hot flashes.Aim of the studyAim of the study is to determine and compare the rate of menopausal symptoms among women living in continents of both Americas, Africa, Australia and Eurasia.Material and methodsThe results of this work were obtained in 2014 on the basis of the data from a review of the 64 most important studies using the PubMed database. Research published in the period 2000-2014, from Africa, both Americas, Australia and Eurasia, were taken into account.ResultsThe prevalence of menopausal symptoms in African women is disconcertingly high. Women from South America complain about occurrence of depressive, sexual dysfunctions and discomfort associated with muscle pain and joint aches. Symptoms most reported by women in the United States are pains associated with muscles and joints. Women in Australia suffer mainly due to vasomotor symptoms and sexual dysfunction, while in the group of women surveyed in Asia there is observed an alarming increase in the proportion of women reporting depressive disorders. In Europe there was a much greater incidence of sleep disorders and depressive disorders.ConclusionsWomen around the world suffer from ailments characteristic for the menopausal period regardless of ethnic origin, skin color or socio-demographic factors.
This article provides a detailed review of current knowledge on the role of vitamin D and its receptor in the biology and management of uterine fibroids (UFs). Authors present ideas for future steps in this area. A literature search was conducted in PubMed using the following key words: “uterine fibroid” and “vitamin D”. The results of the available studies, published in English from January 2002 up to April 2018, have been discussed. Vitamin D is a group of steroid compounds with a powerful impact on many parts of the human body. This vitamin is believed to regulate cell proliferation and differentiation, inhibit angiogenesis, and stimulate apoptosis. Nowadays, hypovitaminosis D is believed to be a major risk factor in the development of UFs. In many studies vitamin D appears to be a powerful factor against UFs, resulting in inhibition of tumor cell division and a significant reduction in its size, however, the exact role of this compound and its receptor in the pathophysiology of UFs is not fully understood. According to available studies, vitamin D and its analogs seem to be promising, effective, and low-cost compounds in the management of UFs and their clinical symptoms, and the anti-tumor activities of vitamin D play an important role in UF biology. The synergy between vitamin D and selected anti-UF drugs is a very interesting issue which requires further research. Further studies about the biological effect of vitamin D on UF biology are essential. Vitamin D preparations (alone or as a co-drugs) could become new tools in the fight with UFs, with the additional beneficial pleiotropic effect.
IntroductionFertility is referred to the capability for having offspring and can be evaluated by fertility rate. Women’s fertility is strictly dependent on individual’s age. The fertility peak occurs in the early 20s, and it starts to decline in the third and fourth decades of life (falling sharply after age 35).AimThe aim of this work is to review the available data concerning fertility in women of late reproductive age, especially the role of serum anti-Müllerian hormone (AMH) levels.Results There are a lot of factors responsible for decrease of fertility in women of late reproductive age. These factors can be classified as oocyte-dependent (decrease in oocyte quantity and quality) and oocyte-independent (reproductive organs [uterus, oviducts] status and general health). Anti-Müllerian hormone (AMH) is a dimeric glycoprotein of the transforming growth factor-β (TGF-β) superfamily produced directly by the ovarian granulosa cells of secondary, preantral, and early antral follicles. It has been used as an ovarian reserve marker since 2002. Anti-Müllerian hormone seems to be the best endocrine marker for assessing the age-related decline of the ovarian pool in healthy women. Evaluation of AMH’s predictive value in the naturally aging population is important for counseling women about reproductive planning as well as for treatment planning for women experiencing hormone-sensitive gynecological conditions such as endometriosis and fibroids.Conclusions AMH can be considered as an indicator of fertility in late reproductive age women and pregnancy outcome in assisted reproductive technology cycles. AMH can strongly predict poor response in the controlled ovarian stimulation.
Uterine fibroids (UFs) are the most common benign tumors of the female genital tract. The incidence of UFs has been estimated at 25–80% depending on selected population. The pathophysiology of UFs remains poorly understood. The transformation of smooth muscle cells of the uterus into abnormal, immortal cells, capable of clonal division, is the main component of all pathways leading to UF tumor formation and tumor necrosis factor α (TNF-α) is believed to be one of the key factors in this field. TNF-α is a cell signaling protein involved in systemic inflammation and is one of the cytokines responsible for the acute phase reaction. This publication presents current data about the role of tumor necrosis factor α in the biology of UFs and the related symptoms. TNF-α is an extremely important cytokine associated with the biology of UFs, UF-related symptoms and complaints. Its concentration has been proven to be elevated in women with clinically symptomatic UFs. The presented data suggest the presence of an “inflammation-like” state in women with UFs where TNF-α is a potent inflammation inducer. The origin of numerous symptoms reported by women with UFs can be traced back to the TNF-α influence. Nevertheless, our knowledge on this subject remains limited and TNF-α dependent pathways in UF pathophysiology should be investigated further.
Background: Cesarean section is a surgical procedure, which is the most frequently performed in gynecology and obstetrics. It is commonly believed that an operative delivery is a less painful and safer mode of delivery, which translates into an increasing number of the procedures performed without medical indications. The maternal sequelae of cesarean sections are well elucidated and widely discussed in the literature, while long-term neonatal consequences still remain the issue of research and scientific dispute. The aim of the present paper was to perform a systematic review of current literature regarding pediatrics consequences of cesarean section. Methods: We reviewed available data from PubMed, Science Direct as well as Google Scholar bases concerning early and long-term neonatal sequelae of operative deliveries. The following key words were used: “cesarean section”, “caesarean section”, “neonatal outcomes”, “respiratory disorders”, “asthma”, “obesity”, “overweight”, and “neurological disorders”. A total of 1636 papers were retrieved out of which 27 were selected for the final systematic review whereas 16 articles provided data for meta-analysis. Statistical analyses were performed using RevMan 5.4. To determine the strength of association between the caesarean section and respiratory tract infections, asthma, diabetes type 1 as well as obesity the pooled odds ratios (OR) with the 95% confidence intervals (CI) were calculated. Results: Conducted meta-analyses revealed that caesarean section is a risk factor for respiratory tract infections (pooled OR = 1.30 95%CI 1.06–1.60, p = 0.001), asthma (pooled OR = 1.23 95%CI 1.14–1.33, p < 0.00001) as well as obesity (pooled OR = 1.35 95%CI 1.29–1.41, p < 0.00001) in offspring. Conclusions: The results of the studies included indicated that children delivered by cesarean section more commonly developed respiratory tract infections, obesity and the manifestations of asthma than children delivered vaginally. The risk of developing diabetes mellitus type 1 or neurological disorders in offspring after caesarean section is still under discussion.
Epilepsy is the most common neurological disorder during pregnancy [1]. About one-third of women with epilepsy are of childbearing age. Statistically, between 0.3% and 0.5% of births occur in women with epilepsy [2]. Every year in Poland epilepsy poses a threat to the health of some 1800 pregnant women and their fetuses. According to British studies, the risk of death in pregnant women with epilepsy increases tenfold compared to pregnant women without epilepsy, mainly due to sudden unexpected death in epilepsy (SUDEP) [3]. Diagnostic and therapeutic advances in the field of epilepsy have contributed to better seizure control. As a result, more and more women with epilepsy become pregnant and more than 90% give birth to healthy children [4,5]. In order to avoid irregularities in the management of women suffering from epilepsy, it is very important to create standards for the management of women treated for epilepsy, both for those who are already pregnant and those who plan pregnancy. Thus the first edition of guidelines regarding management and care in women with epilepsy during preconception period and also during pregnancy, delivery, and postpartum were prepared by the experts of Polish Society of Epileptology and Polish Gynecological Society. The diagnosis, seizures classification and therapy of epilepsy were not included into the guidelines.The neurologists, gynecologists and family doctors should inform that the women with epilepsy could benefit from planning pregnancies to reduce the risk of fetal congenital malformations. Due to increased awareness and knowledge concerning epilepsy, the number of planned pregnancies is increasing, but 40% are still unplanned. The risk of major congenital malformations in the fetus increases in women with epilepsy taking antiepileptic drugs [6]. Fears of women with epilepsy in relation to the adverse effects of antiepileptic drugs on infants can lead to arbitrary withdrawal or dose reduction of antiepileptic drugs, and thus increase the risk of seizures and even SUDEP [4]. Therefore, women of reproductive age (15-44 years) treated for epilepsy should receive care from specialist epilepsy and gynecology clinics. DIAGNOSIS OF EPILEPSYEpilepsy is a heterogeneous group of diseases of the brain, the common symptoms of which are clinical seizures. After diagnosis of epilepsy, a neurologist determines the type of epileptic seizure and suggests appropriate treatment for epilepsy. Based on the course of the disease, neurologist can assess the degree of risk of neurological complications in pregnancy. Women who have not experienced seizures for at least 10 years (including five years without antiepileptic drugs) and those who were diagnosed with childhood epileptic syndrome, but have not experienced seizures in
