Comparative analysis of syphilis incidence among pregnant women in Russia and China: epidemiology, control strategies, and prevention

Orlova E.V., Sosnova E.A., Samchuk P.M., Smirnova L.M., Borshcheva K.R., Orlova L.O.

Abstract

Despite similarities in healthcare system organization, the incidence of congenital syphilis remains stable in Russia, whereas a marked decline has been achieved in China. The question remains which systemic factors constitute key barriers in Russia. This study seeks to identify and quantitatively assess specific gaps in screening, monitoring, and treatment of syphilis among pregnant women in Russia that hinder effective adoption of successful Chinese practices. The work aimed to perform a comparative analysis of syphilis incidence among pregnant women in Russia and China. A retrospective analysis was conducted using data from the Russian Federal State Statistics Service, the Chinese Center for Disease Control and Prevention, and scientific publications (2013–2023).

In China, a decline in syphilis incidence among pregnant women has been observed due to mandatory trimester-based screening (coverage > 99%) and a comprehensive program for the prevention of mother-to-child transmission. The incidence of congenital syphilis decreased from 91.6 to 18.4 cases per 100,000 live births (between 2011 and 2018). In Russia, the incidence remains consistently high (13.1–17.6 per 100,000 population in 2020–2023), with more than 30% of women entering antenatal care in the second or third trimester. Data on treatment coverage are lacking. Reducing the burden of congenital syphilis in Russia may be facilitated by standardization of screening protocols and implementation of monitoring systems ensuring early antenatal registration. The success of the Chinese model is driven by comprehensive screening and integration of services within the national healthcare system, which is comparable to that of the Russian Federation.

Impact of the glucagon-like peptide-1 receptor agonist semaglutide on reproductive health of women with obesity: a review of clinical evidence

Luzik Y.V., Svidinskaya E.A., Baburin D.V., Ageev M.B., Proklova G.F., Sosnova E.A.

Abstract

Currently, the problem of overweight and obesity has acquired global significance due to the high prevalence of these conditions and the associated multisystem pathological conditions, including reproductive disorders in both men and women. Contemporary medicine strongly recommends weight reduction to prevent metabolic complications and obesity-related comorbidities. The most effective and fundamental approach remains lifestyle modification, including a hypocaloric diet and moderate physical activity. However, a proportion of patients demonstrate resistance to such changes, necessitating the use of pharmacological agents and, in some cases, surgical treatment. Semaglutide, a glucagon-like peptide-1 receptor agonist, has demonstrated high efficacy in reducing body weight and improving glycemic control in patients with obesity and type 2 diabetes mellitus. However, data on the effects of semaglutide on the female reproductive system remain limited, as long-term clinical observations and studies under extreme conditions have been predominantly conducted in animal models. Particular attention is given to the effects of the drug in women of reproductive age, including its impact during preconception, the first trimester of pregnancy, and lactation, when both inadvertent and intentional exposure may have unpredictable consequences for the fetus and infant.

This study presents a systematic review of current evidence regarding the use of semaglutide in female patients with obesity and examines the associated risks and contraindications during specific physiological states such as pregnancy and lactation. The findings are of substantial importance for developong clinical guidelines and establishing safe therapeutic strategies, which are essential for preserving reproductive health and supporting demographic stability.

Application of PRP-therapy in assisted reproductive technology

Filimonova O.V., Pandya S.K., Osadchev V.B., Proklova G.F., Pobedinskaya O.S., Kanokova I.N., Safonova N.E.

Abstract

According to the World Health Organization, infertility affects 17.5% of the adult population worldwide and remains a serious medical and social challenge. Despite significant progress in assisted reproductive technologies, the treatment of infertility associated with endometrial disorder and ovarian dysfunction remains relevant and requires the search for new therapeutic approaches.

This review analyzes current data from Russian and international sources published over the past 5 years on the use of autologous platelet-rich plasma (PRP) as a promising therapeutic modality in assisted reproductive technology programs. The search for published data was conducted in PubMed, eLibrary, and Google Scholar databases. Analysis of the publications demonstrated that PRP therapy is clinically effective in treating thin endometrium, recurrent implantation failure, and premature ovarian insufficiency and may also improve the clinical pregnancy rate. However, the available studies are limited by small sample sizes and nonrandomized designs, precluding definitive conclusions regarding the efficacy and safety of PRP therapy. Additionally, different routes of administration, injected plasma volumes, and platelet concentrations are currently in use. However, their efficacy has not been compared against one another but only against control groups receiving conservative therapy. This technology requires further investigation in randomized clinical trials to develop standardized protocols and evaluate long-term outcomes.

Management of pregnancy in patients with rheumatic diseases: modern therapeutic options

Khudyakova V.A., Kosheleva A.A., Babaeva M.M., Ageev M.B., Svidinskaya E.A., Sosnova E.A.

Abstract

Rheumatic diseases such as systemic lupus erythematosus and rheumatoid arthritis frequently begin in reproductive age, resulting in a high incidence of autoimmune disorders during pregnancy. Managing these patients is challenging, necessitating a balance between effective control of rheumatic disease activity for a favorable pregnancy outcome and minimizing risks to the fetus.

This paper summarizes modern approaches to preconception care, pregnancy management, safe therapy selection, and monitoring of complications in patients with rheumatic diseases, primarily systemic lupus erythematosus and rheumatoid arthritis. The paper reviews relevant guidelines, including the updated 2024 EULAR, data from national and international registries, and findings of cohort and retrospective studies on pregnancy outcomes in patients with rheumatic diseases.

Rheumatic disease activity during conception and gestation is a key predictor of adverse outcomes such as pre-eclampsia, fetal growth retardation, preterm delivery, and congenital abnormalities. Achieving sustained remission 6–12 months before pregnancy considerably increases the likelihood of having a healthy child. The therapeutic strategy is based on the personalized selection of drugs that are suitable for pregnancy and lactation. Hydroxychloroquine is essential for the treatment of systemic lupus erythematosus owing to its immunomodulatory and antithrombotic properties, established safety profile, and positive impact on outcomes. Tumor necrosis factor inhibitors can be used in rheumatoid arthritis until late pregnancy or in patients with high disease activity. Methotrexate, mycophenolate mofetil, and cyclophosphamide are strictly contraindicated during pregnancy and must be discontinued at the planning stage. Effective disease control requires multidisciplinary collaboration between a rheumatologist and an obstetrician-gynecologist at all stages, from preconception counseling and follow-up during pregnancy to postpartum care.

Thus, favorable pregnancy outcomes in patients with rheumatic diseases are possible with careful pregnancy planning when in remission, safe and effective maintenance therapy, and continuous multidisciplinary monitoring. Adherence to these principles reduces risks for both mother and fetus.

Proliferative activity and expression of estrogen receptors in endometrial mesenchymal stromal cells in patients with repeated implantation failure

Ivashchenko D.V., Mangusheva V.A., Sysoeva V.Y., Eremichev R.Y., Nikitina T.V., Shcherbakova L.N., Makarevich P.I., Mladova E.S., Kalinina N.I., Panina O.B.

Abstract

BACKGROUND: Endometrial receptivity disorders are the primary focus in patients with repeated implantation failure. However, the cellular and receptor characteristics of endometrial mesenchymal stromal cells in this population remain poorly understood, especially in terms of proliferative activity and estrogen receptor expression. This work examined the proliferative activity and expression of estrogen receptors in endometrial mesenchymal stromal cells in these patients to identify a new pathogenetic link of infertility and potential therapeutic targets.

AIM: The work aimed to assess the functional characteristics of endometrial mesenchymal stromal cells, including their proliferative activity and estrogen receptor expression, in patients with repeated failure of euploid embryo implantation.

METHODS: This pilot study included five patients aged 25–40 years. The main group included four patients with repeated implantation failure. An endometrial sample from a surrogate mother with a history of six term births served as a positive control. Mesenchymal stromal cells were isolated from endometrial aspiration biopsy samples collected during the first phase of the menstrual cycle. ESR1 expression was assessed by real-time polymerase chain reaction, and estrogen receptor alpha (ERα) levels were measured by fluorescent immunocytochemistry. The proliferative activity of mesenchymal stromal cells was assessed in the IncuCyte live-cell analysis system in a control medium and with 0.1 nM 17β-estradiol.

RESULTS: ESR1 mRNA levels in cultured endometrial mesenchymal stromal cells were approximately 10 times higher than in adipose tissue mesenchymal stromal cells. Immunocytochemistry revealed specific expression of nuclear ERα in all samples. Patients with unexplained infertility had fewer receptors than the control group, with the lowest ERα expression reported in patients with tubal-peritoneal infertility. Endometrial mesenchymal stromal cells from patients with repeated implantation failure had a significantly lower proliferation rate than mesenchymal stromal cells from a surrogate mother. Patients with unexplained infertility had the lowest proliferative capacity of endometrial mesenchymal stromal cells. Adding 17β-estradiol significantly increased endometrial mesenchymal stromal cell proliferation in both the surrogate mother and patients with unexplained infertility. In patients with tubal-peritoneal infertility, 0.1 nM estradiol did not improve endometrial mesenchymal stromal cells proliferation.

CONCLUSION: This work is the first to demonstrate decreased proliferative activity and expression of estrogen receptors (ERα) in endometrial mesenchymal stromal cells in patients with repeated implantation failure. The findings indicate that mesenchymal stromal cells from patients with unexplained infertility remain sensitive to estrogen despite the reduced number of receptors. These data add to a better understanding of the functional characteristics of endometrial mesenchymal stromal cells in repeated implantation failure.

Maternal renal and ophthalmic artery doppler parameters in predicting pregnancy-induced hypertension

Bulanova M.M., Shamugiya V.V., Ponimanskaya M.A., Andreeva E.Y., Kaiibkhanova K.M., Panina O.B.

Abstract

BACKGROUND: Pregnancy-induced hypertension is one of the leading causes of maternal and perinatal morbidity and mortality. Identifying high-risk patients enables timely prevention of this complication. Existing models can predict individual risk of pregnancy-induced hypertension with up to 80% accuracy, indicating that additional markers and risk factors need to be identified to improve their performance.

AIM: The work aimed to assess the relationship between maternal renal and ophthalmic artery Doppler parameters in the first and second trimesters and the risk of pregnancy-induced hypertension.

METHODS: A prospective, single-center observational study was conducted. During the first and second prenatal screenings, the renal (resistance index) and ophthalmic (resistance index, pulsation index, velocity, peak ratio [PR], and DV/P2) artery Doppler parameters were additionally assessed. The course of pregnancy and its outcomes were then assessed, and the examined blood flow parameters were compared between patients with uncomplicated pregnancy and those with pregnancy-induced hypertension.

RESULTS: The study included 353 pregnant women, with 135 receiving a follow-up examination in the second trimester. Pregnancy outcomes were reported for 324 patients who were initially included in the study. Pregnancy-induced hypertension was reported in 32 patients. These patients had significantly higher body mass index and systolic, diastolic, and mean blood pressure (p < 0.001 for all). Moreover, they had higher average and maximum PR values (p = 0.036 and p = 0.036, respectively) and lower average and maximum DV/P2 values (p = 0.041 and p = 0.015, respectively) at 19–21 weeks of pregnancy. The risk of pregnancy-induced hypertension was 2.4 and 3.4 times higher in patients with PR > 0.55 in the first trimester and PR > 0.60 in the second trimester, respectively. Furthermore, the risk of pregnancy-induced hypertension was 7.3 times higher in patients with DV/P2 < 0.90 in the second trimester.

CONCLUSION: The study identified distinctive characteristics of the ophthalmic artery blood flow in patients with pregnancy-induced hypertension. Further research is needed to assess the role of these patterns in predicting individual risks of pregnancy complications.

Reproductive life planning in Sechenov University students: a survey

Baburin D.V., Svidinskaya E.A., Ageev M.B., Chushkov Y.V., Luzik Y.V., Shchetkina M.A.

Abstract

BACKGROUND: Medical students, as future doctors, have a prominent role in shaping medical culture and public opinion. Creating educational programs, events, and campaigns to support families with children, as well as instilling a positive attitude towards multi-child parenting in medical students, can help to increase birth rates in the near future.

AIM: The work aimed to analyze the reproductive potential of medical students, identify factors influencing birth rates, and assess the commitment to traditional family values among young people.

METHODS: An anonymous online survey among Sechenov University students was conducted. Primary endpoint: to obtain the results of the online survey (completed online questionnaires). Secondary endpoints: to analyze the findings and perform a comparative analysis of the answers based on the year of study and sex.

RESULTS: The survey was conducted between August and December 2024. A total of 1785 students responded, including 1441 (80.7%) females and 344 (19.3%) males. The majority of respondents do not plan to have children while attending the University, citing financial constraints, housing issues, and concerns about the impact on their careers and childbirth. One of the main reasons for delaying motherhood is the desire for self-fulfillment and a successful career. Many female respondents claim that they delay having children in order to pursue a career and provide for themselves financially. A college degree leads to a desire for a higher social status, and women who pursue college education have more options for effective self-fulfillment outside of motherhood.

CONCLUSION: Sustainable population growth necessitates long-term efforts to improve welfare and strengthen families. One potential strategy is to encourage medical students to promote family values and support multi-child parenting. The majority of medical students surveyed prioritize a successful career over family planning, without considering the age-related decline in fertility.

Intrapartum cesarean section: clinical characteristics, demographics, medical history, and course of pregnancy and labor

Zhilkina A.A., Krivonosova D.A., Alekseenkova M.V., Panina O.B.

Abstract

BACKGROUND: Cesarean delivery rates continue to rise, as does the percentage of intrapartum cesarean section, highlighting the relevance of research on the subject. Risk factors for emergency cesarean delivery include a burdened medical or obstetric and gynecological history (hypertension, diabetes mellitus, etc.) as well as pregnancy complications (pregnancy-induced hypertension, pre-eclampsia, gestational diabetes, fetal malpresentation, etc.). Analyzing these factors can help to identify risk groups, improve labor management, and reduce maternal and neonatal morbidity.

AIM: The work aimed to assess the impact of maternal history and course of labor on the mode of delivery and neonatal outcomes.

METHODS: The study included 391 patients. Patients were divided into the main group (intrapartum cesarean section) and the control group (cesarean section before the onset of labor). The main group was divided into three subgroups. Subgroup 1 (latent phase) included 48 patients who had a cesarean section at a cervical dilatation of 1–4 cm; subgroup 2 (active phase) included 43 patients who had a cesarean section at a cervical dilatation of 5–9 cm; and subgroup 3 included 195 patients who had a cesarean section at full dilatation. The control group (n = 105) included patients who had a cesarean section before the onset of labor. Each patient's medical records on the course of pregnancy and labor and mode of delivery were analyzed.

RESULTS: Overweight and obesity were most common in the control group; moreover, this group had the shortest gestational age at the time of cesarean section. Chronic hypertension was more common in the active phase subgroup than in the full dilatation subgroup (р < 0.05). Oxytocin induction was less common in the full dilatation subgroup (p < 0.05). In the latent phase subgroup, primary uterine inertia was the most common indication for cesarean section (p < 0.05), whereas secondary inertia was more common in the active phase and full dilatation subgroups (р < 0.05). The full dilatation subgroup had the highest intraoperative blood loss (~ 600 mL; p < 0.05). The highest birth weight was reported in the full dilatation subgroup (3632 g; p < 0.05), while the highest 1-minute Apgar scores were observed in the latent phase subgroup (8 points; p < 0.05).

CONCLUSION: The maternal history and course of labor have a direct impact on the mode of delivery and neonatal outcomes. The findings highlight the relevance of assessing maternal history and course of labor in real-world practice.

Uterocervicovaginal fistula as a complication after vaginal metroplasty

Batenkova T.A., Fedorov A.A., Suslikova D.V., Sopova J.I., Kapitanova O.V.

Abstract

A uterine scar is a connective tissue area in the myometrium that results from surgical intervention, injury, or inflammation. It is characterized by the replacement of smooth muscle fibers with fibrous tissue, as well as abnormalities in myometrial vascularization, innervation, and architecture. These abnormal changes impair the function of the uterus and increase the risk of obstetric and gynecological complications. The rising global cesarean section rates continue to be a major concern. In Russia, they were 30.1% in 2022, which is comparable to North America (32.3%), lower than in Latin America (40.5%) and Turkey (57.2%), but considerably higher than the WHO-recommended threshold of 10%–15%. As cesarean section rates increase, so does the number of patients with postoperative uterine scars and specific complications. These complications include isthmocele with myometrial thinning at the scar site (residual myometrial thickness at the scar site < 3–2.5 mm on ultrasound). Preconception monitoring is used to minimize risks, with surgical treatment (metroplasty) as indicated. Metroplasty, however, carries the risk of complications such as genital fistulas, which are uncommon but clinically significant. This article presents a clinical case of a uterocervicovaginal fistula after vaginal metroplasty. According to the medical history, a patient with uterine isthmocele in the lower segment had a spontaneous singleton pregnancy after surgical treatment. The pregnancy ended in abortion with expulsion of the gestational sac through the fistulous opening. The patient underwent repeat surgery at the Department of Operative Gynecology and Gynecologic Oncology with Day Hospital, V.I. Krasnopolsky Moscow Regional Research Institute of Obstetrics and Gynecology. The procedure aimed to restore the anatomic integrity of the reproductive organs and to provide preconception care for a future pregnancy. This is the first published report of this complication, highlighting its clinical and scientific significance.
