Recurrent pregnancy loss is a complex health challenge with no universally accepted definition. Inconsistency in definitions involves not only the number of spontaneous abortions (two or three) that are accepted for recurrent pregnancy loss but the types of pregnancy and gestational age at miscarriage. Due to the heterogeneity of definitions and criteria applied by international guidelines for recurrent pregnancy loss, the true incidence of recurrent miscarriage, which is reported to range from 1% to 5%, is difficult to estimate. Moreover, the exact etiology of recurrent pregnancy loss remains questionable; thus, it is considered a polyetiological and multifactorial condition with many modifiable and non-modifiable factors involved. Even after thoroughly evaluating recurrent pregnancy loss etiology and risk factors, up to 75% of cases remain unexplained. This review aimed to summarize and critically analyze accumulated knowledge on the etiology, risk factors, relevant diagnostic options, and management approach to recurrent pregnancy loss. The relevance of various factors and their proposed roles in recurrent pregnancy loss pathogenesis remains a matter of discussion. The diagnostic approach and the management largely depend on the etiology and risk factors taken into consideration by a healthcare professional as a cause of recurrent miscarriage for a particular woman or couple. Underestimation of social and health consequences of recurrent pregnancy loss leads to compromised reproductive health and psychological well-being of women after miscarriage. Studies on etiology and risk factors for recurrent pregnancy loss, especially idiopathic, should be continued. The existing international guidelines require updates to assist clinical practice.

Although it is clear that infertility leads to heightened stress for patients, the impact of depressed mood and anxiety on treatment outcome is inconsistently reported. The aim of this study was to evaluate the effect of stress, depression and anxiety on in vitro fertilization (IVF) outcomes in Kazakhstani public assisted reproductive technology (ART) clinics. The prospective cohort study was performed between June 2019 and September 2020 using questionnaires to assess psychological stress, depressed mood and anxiety in women referred to IVF clinics in two public clinical centers in Kazakhstan, Nur-Sultan and Aktobe. Our study sample comprised 142 women with the average age of 33.9 ± 4.9 years, and infertility duration 6.0 ± 3.5 years. More than half of respondents had Center for Epidemiological Studies Depression Scale (CES-D) scores higher than 16, indicating their risk of developing clinical depression. Ninety-one percent of women from Aktobe city were at risk for clinical depression (p < 0.001). Aktobe city respondents had higher stress subscale scores and anxiety scale scores (p < 0.001) than Nur-Sultan respondents. Statistical analysis showed that IVF outcome was not significantly associated with depression and stress, while the higher anxiety scale scores were negatively associated with clinical pregnancy after IVF.

The rationale and importance of folic acid supplementation during pregnancy for fetal congenital defect prevention are accepted worldwide. Moreover, a sufficient plasma concentration of folates can reduce the incidence of spontaneous abortions, and support the normal expansion of placental blood vessels, ensuring physiological placental blood flow, thus promoting appropriate fetal growth and development. Furthermore, there is emerging evidence that long-term supplementation with folic acid can effectively prevent preeclampsia. Preeclampsia is unique to the human species in complications during pregnancy, which contributes to maternal and perinatal mortality worldwide. In the pathogenesis of preeclampsia abnormal placental invasion, the excess of antiangiogenic factors and maternal–placental syndrome play a key role. Increased blood levels of homocysteine during pregnancy are associated with the risk of preeclampsia. Moreover, hyperhomocysteinemia has been proposed to be an independent risk factor for preeclampsia. Folate supplementation helps to decrease elevated levels of homocysteine; thus, the role of folic acid supplementation in pregnancy is even more important. Multiple reports suggest that folate administration decreases the level of serum homocysteine and, therefore, reduce the risk and severity of preeclampsia. However, the association between folic acid supplementation and the decreased risk of preeclampsia has been investigated with controversial conclusions. Currently, the optimal dose of folic acid that is effective for preeclampsia prevention remains uncertain. In this review, we aim to summarize the accumulated knowledge on the role of folic acid in the pathogenesis of preeclampsia, and the possible impact of folate supplementation on the decreased risk of preeclampsia.

The aim of this study was to conduct a nationwide high-risk human papillomavirus (HR-HPV) infection genotyping analysis of women attending gynecological clinics. In addition, this study aimed to identify factors that are associated with HR-HPV infection. This was a cross-sectional survey-based study with 759 participants. Demographics, lifestyle, and medical history data was collected with a questionnaire that was filled by gynecologists during patients' visit. Cervical swabs were used as a source for HPV genotyping using AmpliSens kit. Data analysis was carried out which included descriptive statistics consisting of mean values, standard deviations, and frequencies, where applicable. To identify factors associated with HPV infection status, ordinal logistic regression was built. The mean age of the participants was 36.51 ± 10.09 years. The majority of women who participated in this study were aged between 26 and 35 years. Less than half of the women (39%) were HPV positive, 26% of participants had a single HR-HPV and 13% had multiple HR-HPV infections. The most prevalent HR-HPV genotypes were HPV-16 (54%), HPV-51 (7%), HPV-68 (7%), and HPV-18 (6%). The results of ordinal logistic regression demonstrated that factors such as older age, not being single, and having history of sexually transmitted infections (STIs), decrease the odds of having HPV infection. This study identified high prevalence of HR-HPV among Kazakhstani women. Apart from this, our results showed that adding HPV testing to compulsory cervical cancer screening in Kazakhstan could help to improve the screening program and decrease the rates of cervical cancer.

Background/Objectives: Persistent high-risk human papillomavirus (HPV) infections are the leading cause of cervical cancer. Developing evidence suggests that the cervicovaginal microbiome plays a significant role in modulating HPV persistence and progression to cervical neoplasia. This review synthesizes the current knowledge on the interplay between the cervicovaginal microbiome and local immunity in HPV infections, emphasizing microbial diversity, immune responses, and potential therapeutic implications. Methods: A thorough review of the literature was performed using Embase, PubMed, Scopus, and Google Scholar, encompassing studies published between 2000 and 2024. Studies examining the composition of the microbiome, immune responses, and HPV-related outcomes were evaluated and synthesized into a comprehensive review. Results: A Lactobacillus-dominant microbiome, particularly with L. crispatus, creates a protective environment through lactic acid production, maintenance of low pH, and anti-inflammatory immune modulation, facilitating HPV clearance. Dysbiosis, often characterized by a dominance of L. iners and overgrowth of anaerobic bacteria, fosters chronic inflammation, cytokine imbalance, and a microenvironment conducive to HPV persistence and progression. Hormonal changes and menopause exacerbate these microbial shifts, increasing the risk of cervical lesions. Studies suggest that cytokine profiles and antimicrobial peptides significantly influence local immune responses, further modulating infection outcomes. Conclusions: The cervicovaginal microbiome is a critical determinant in HPV infection outcomes, with therapeutic potential for modulating the microbiome to enhance immune responses and prevent cervical cancer. Personalized microbiome-targeted therapies may offer a novel avenue for managing HPV and reducing cervical cancer incidence.

Background: Pipelle endometrial biopsy is vital for the early diagnostics of endometrial pathology and is performed in outpatient setting in minimally invasive manner. One of the reported disadvantages of sampling with Pipelle curette is failure to collect enough tissue for histological analysis. The role of psychological factors such as anxiety and pain sensitivity in obtaining adequate samples is not well known. The study's objective was to explore whether there is relationship between severe pain, anxiety, and the rate of Pipelle failure.Methods: Study included 158 women with median age of 42 who underwent Pipelle endometrial biopsy at Clinical Academic Department of Women’s Health of the University Medical Center (UMC), Nur-Sultan City, Kazakhstan with an abnormal uterine bleeding from June 2019 to April 2021. Women were asked to fill survey on pain, anxiety before, during and after the procedure.Results: 3.8%, 15.19% and 4.43% of women reported severe pain and 39.24%, 34.18% and 14.56% of women reported severe anxiety prior, during and after procedure, respectively. Women who experienced severe pain during procedure tend to be more anxious during procedure (p = 0.0001) and have higher number of sampling attempts (p = 0.0040). Pain level was higher among patients sampled by the junior OB/GYN specialist (p < 0.0001). We found no differences in Pipelle biopsy success rates in relationship to baseline, during and postprocedural pain and anxiety scores.Conclusion: Anxiety during procedure performance was significantly associated with severe pain during the procedure but did not represent a key element for the success of Pipelle biopsy.
