Threshold values of antibodies to estrogen, progesteron and benzo [a] pyrene as a risk factor for the development of endometriosis.

Objectives: The objective of the study was to determine the level of antibodies (AB) of Ig classes A and G to estradiol (E2), progesterone (P) and benzo [a] pyrene (Bp) in patients with endometriosis of various severity and estimate their threshold values as a risk factor for the development of endometriosis.

Methods: A retrospective case-control study was performed. The study involved 200 women.

Perinatal outcomes in pregnant women with COVID-19 in Siberia and the Russian Far East.

Objective: To assess the incidence and perinatal outcomes of COVID-19 in pregnant women in the Far Eastern and Siberian Federal Districts of Russian Federation over 10 months of a pandemic.

Materials And Methods: This was secondary analysis of Public Data basis on 25 Dec 2020. Statistics included descriptive statistics, analysis of contingency tables, which assessed the value of , the achieved significance level ().

Device-assisted pelvic floor muscle postpartum exercise programme for the management of pelvic floor dysfunction after delivery.

Background: Pelvic floor dysfunction (PFD) is a multifactorial condition that clinically manifests as the pelvic prolapse, urinary and/or rectal incontinence, and sexual dysfunction.

Aim: We aimed to evaluate the efficacy of two pelvic floor trainers for the prevention of PFD in women during the postpartum period.

Materials And Methods: This was a prospective, randomized, open-label study in 70 women in the postpartum period.

Analysis of risk factors and predictors of pregnancy loss and strategies for the management of cervical insufficiency in pregnant women at a high risk of preterm birth.

Aim: To identify risk factors and predictors of pregnancy loss and to compare the efficacy of Arabin's pessary with cervical cerclage in women at a high risk of pregnancy loss.

Materials And Methods: This was a two-center retrospective case-control study that included 240 women at a high risk of preterm delivery. Group I ( = 161) included women who underwent insertion of the Arabin's pessary between 14 and 24 weeks of pregnancy.

Adenomyosis: genetics of estrogen metabolism.

Background To analyze the allelic variants of genes of enzymes involved in estrogen metabolism: CYP1A1, CYP1A2, CYP19 and SULT1A1 using polymerase chain reaction-restriction fragment length polymorphism-restriction fragment length polymorphism (PCR-RFLP) analysis of women with histologically confirmed adenomyosis and women without proliferative diseases of pelvic organs was performed. We studied the following polymorphisms: CYP1A1 M1, T264 → C transition in the 3'-noncoding region; CYP1A2*1F, C734 → A transversion in CYP1A2 gene; C → T transition (Arg264Cys) in exon 7 of CYP19; SULT1A1*2, G638 → A transition (Arg213His) in the SULT1A1 gene. Materials and methods The study included 804 patients.

Ovarian reserve in adolescent girls born prematurely.

Background The objective was to estimate ovarian reserve in adolescent girls born prematurely. Materials and methods Two hundred adolescent girls aged 15-16 years who were born prematurely and full term were studied with laboratory, ultrasound and statistical methods. Results Statistically significant differences of the main parameters that characterize ovarian reserve in adolescent girls born prematurely compared to those born full term were specified.

Basic pituitary-ovarian hormones and ultrasound parameters of uterine appendages in full-term and preterm neonate girls.

Objective To determine the basic pituitary-ovarian hormones and ultrasound parameters of uterine appendages in full-term and preterm newborn girls. Materials and methods One hundred full-term and premature newborn girls (58 and 42, respectively) were studied with clinical, instrumental, laboratory (enzyme immunoassay) and statistical methods. Results Statistically significant differences in the pituitary-ovarian hormones and ultrasound parameters of uterine appendages in preterm neonate girls compared to full-term girls were defined.
