The study of factors influencing the formation of puberty is an urgent issue for improving the demographic situation in the country. Purpose — to analyze the nature of the pubertogenesis's progress of adolescent girls depending on body weight at birth. Materials and methods. A retrospective analysis was made of the course of pregnancy and childbirth of mothers of girls born with low or overweight. Menstrual function and somatic status among the study groups were prospectively assessed to identify markers of start and puberty disorders. Results. The data obtained showed the reliability of the influence of body weight at birth on the development of menstrual function. Hypomenstrual syndrome was formed under the influence of fetal growth retardation syndrome, and vice versa, hypermenstrual syndrome was based on macrosomia in the antenatal period. Conclusions. The identified features provide an opportunity for further research for the timely optimization of the formation of risk groups in the fertile age.

For fetuses with malformations, dysfunction of the provisional organs (PO) can become critical and affect survival. Expert correct examination of PO during a comprehensive prenatal examination can become a diagnostic and prognostic tool for specialized management of fetuses as patients, and newborns to optimize the system of prenatal dispensary evaluation. Literature review has shown that there are certain patterns of the PO pathology in cases of fetal abnormal development, which require changes in the tactics of prenatal observation and delivery. The variability of morphological/ultrasound changes and clinical outcomes makes it difficult to reach definite diagnosis and make correct decisions about the management of patients in specific cases.

Purpose — to study the features of changes in the state of personal and situational anxiety, stress-implementing and stress-limiting systems of the body in healthy women depending on the method of prenatal training. Materials and methods. 120 somatically healthy women without severe extragenital and obstetric pathology with a physiological course of singleton pregnancy were examined. In the first group — 45 women set up for partner childbirth, the second group also included 45 patients who underwent a course of transcranial electrical stimulation (TES) of mesodiencephalic structures of the brain in comprehensive preparation for partner childbirth. The control group included 30 women who did not receive prenatal training, did not have individual support in childbirth and were tuned to traditional methods of pain relief as needed. Results. Following the results of the determination of pain rate in the dynamic of the TES procedure, a progressive growth of the pain tolerance threshold was recorded with the subsequent stabilization of this value after the 5th procedure of electrical stimulation. Methods of psychophysical preparation for childbirth using transcranial electrostimulation and partner support made it possible to reduce medical induced pain relief during childbirth, which is what the data we obtained indicate. Conclusions. The use of TES in complex prenatal preparation for partner labor allows to achieve and maintain a stable psycho-emotional adaptation of pregnant women and increases the tolerance of the consonant to labor pain without additional medication load, which helps to make more physiological course of labor.

Pravastatin was of the greatest interest among all the proposed therapeutic agents. It has pleiotropic effect, i.e. affects multiple molecular targets against preeclampsia. Proton pump inhibitors, metformin, and sulfasalazine are other drugs that have preclinical evidence of multiple molecular actions that may address the pathophysiology of preeclampsia. Currently, these molecules are also in clinical trials. Many natural compounds for the treatment of preeclampsia, such as plant extracts and trace elements, are being researched to identify the potential in anti-inflammatory or antioxidant activity.

Vulvovaginal candidiasis (VVC) It ranks second among all vaginal infections and is one of the most common mental reasons for women to visit a gynecologist. Obesity and overweight play an important negative role in gynecological and obstetric practice. There has been a significant increase in C. albicans non-albicans in overweight women of reproductive age, and has a negative effect on the reproductive health of women. The article presents the results of a comparative study on the clinical and laboratory effectiveness of local therapy for bacterial vaginosis and IHC in overweight women. Against the background of metabolic disorders, there is an increase in the frequency of infectious pathology of the urogenital tract. Numerous literature data indicate that fungi of the city of Candida are part of various microbial associations and an important factor in their active growth is the deficiency of lactobacilli that produce H2O2. Data on bacterial vaginosis and vulvovaginal candidiasis, development and role of metabolic disorders in the pathogenesis of BV and VVC are presented. Increasing the effectiveness of local treatment of disorders of the vaginal biocenosis in women with overweight and obesity by using individualized dietary nutrition, means of correcting the intestinal biocenosis and metabolic therapy, an integrated approach to the therapy of women of reproductive age showed more effective results. It has been found that overweight and obesity negatively affect the reproductive system of women. Irregular menstrual cycles, secondary amenorrhea, infertility, endometrial hyperplastic processes are often associated with overweight and obesity. In many cases, BV is combined with intestinal dysbiosis. In this case, vaginosis can be considered as a manifestation of a systemic dysbiotic process, affects not only the microbiota of the genitourinary system, but also the endogenous microflora in various cavities of the macroorganism, provided that it is influenced by any exogenous and endogenous factors.

Assessment of the heart rate is one of the obligatory methods of pediatric examination and its deviation from the age norm may indicate a change in the child's health and be one of the first manifestations of the disease. Heart rhythm disturbances accompany various diseases, namely: congenital heart defects, cardiomyopathies, rheumatic and infectious diseases, intoxication, vegetative crises, endocrine diseases, diseases of the nervous system and others. Most often, in children's practice, it is not always possible to establish the cause of heart rhythm disturbances, as well as to classify the presence of organic or functional disorders without conducting morphological studies. Purpose — to study the features of heart rhythm and the state of the autonomic nervous system (ANS) among the children of primary school age with sinus bradycardia. Materials and methods. Children of primary school age with sinus bradycardia were examined (210 children). All children underwent: clinical examination, ECG at rest and after exercise, daily monitoring of ECG and heart rate, echocardiography, cardiointervalography with spectral analysis of heart rate. Results. Assessment of the cardiovascular system among children with bradycardia revealed the following features: 80.0% of children had no complaints, 68.0% of children at the age of 6–7 years and 55.0% of children at the age of 8–10 years had moderate bradycardia, 32.0% of children at the age of 6–7 years and 45.0% of children at the age of 8–10 years had significant bradycardia. After the exercise test, 71.0% of children still had bradycardia, which is typical for children at the age of 9–10 years and 29.0% of children had an acceleration of heart rate above the age norm. Holter monitoring revealed the following cardiac arrhythmias: sinus rhythm driver migration, ectopic rhythm, sinoatrial block, 2 grade atrioventricular block, atrial extrasystole and ventricular extrasystole. Different duration of sinoatrial pauses was detected: in the range from 1300–1400 ms among the most children (78.0%) to 1700–1800 ms among 1.8% of children. Data from spectral analysis of sinus rhythm showed the predominance of parasympathetic nervous system tone among the 84.0% of children, asympathicotonic (40.5%) and normal (44.9%) autonomic reactivity. Conclusions. Examination of the children of the primary school age revealed sinus bradycardia and bradyarrhythmia among the 80.7% of children. Bradyarrhythmia is typical for children at the age of 6–7 years, bradycardia — for children at the age of 9–10 years. Spectral analysis of the ANS showed an imbalance in the regulation of sinus rhythm: the predominance of the parasympathetic link, regardless of the initial state of the ANS and the violation of adaptive mechanisms.
