Cervical Cancer Visual Screening Experience in the Republic of Tajikistan

OBJECTIVES: To study the results of the first pilot study of organized visual cervical cancer (CC) screening for the detection of precancerous pathology of the cervix in two pilot districts of the Republic of Tajikistan. STUDY DESIGN: In this cross-sectional study, the target group included healthy women of reproductive age (30-49 years) from Kushoniyon and B. Gafurov Districts who underwent visual screening. The total study population was 72,574 out of which 68,391 (94.3%) visited primary healthcare facilities for visual inspection with Lugol’s Iodine (VILI). A total of 2958 women with suspicious tests for cervical intraepithelial neoplasia (CIN) were identified (4.3%) and sent to the reproductive health care centers for further diagnostics. Post-screening diagnostic tests were performed to specify cervical lesions, which included colposcopy with acetic acid (VIA) visual inspection, cytology, and biopsy with histological examination. HPV testing wasn’t included in the diagnostic protocol due to its high cost. RESULTS: A total of 164 histologically confirmed cases of CIN were identified (0.25% of number of women screened). The detection rate of precancerous pathology was 26.9 per 100,000 female population, which is 8.2 times higher than the detection rate of CC. All patients regardless of CIN degree underwent loop electrosurgical excision (LEEP)/conization. In the follow-up period (6-48 months), complete recovery after 136 LEEP, 21 conizations, and 7 hysterectomies were observed in 97% (5 recurrences of non-invasive disease). CONCLUSION: The visual screening showed high efficiency in detecting CIN. The positive experience suggests the implementation of this program nationwide.

Overcoming poor ovarian response in assisted reproductive technology programs in patients of late reproductive age

Objective: to increase the effectiveness of in vitro fertilization in patients of late reproductive age by optimizing prepregnancy preparation for the IVF program.Materials and methods: The study included 67 patients of late reproductive age with a history of unsuccessful IVF attempts, divided into two groups at the second stage of the study, depending on the volume of prepregnancy preparation: group 1 (33 patients), group 2 (34 patients). The control group (50 patients) were healthy women of reproductive age. Immunohistochemical examination of the endometrium and microbiological examination of the uterine cavity, hormonal status of peripheral blood, study of the concentration of melatonin in peripheral blood and follicular fluid, antioxidant status of follicular fluid, expression of leukemia inhibitory factor (LIF) in the cervical secretion were performed.Results: in patients with age-related dysregulation of the hypothalamic-pituitary-ovarian axis and impaired fertile function, a systemic and local (in follicles) decrease in melatonin levels was revealed. The studied effects of melatonin suggested that its use in patients of late reproductive age with reduced follicular reserve and a "poor" response to ovarian stimulation may increase the effectiveness of in vitro fertilization (IVF).Conclusions: The inclusion in the pre-gravidar preparation of a complex of water-soluble polypeptide fractions of the epiphysis, stimulating the production of endogenous melatonin, made it possible to increase the effectiveness of IVF in patients by an average of 3.1 times according to the criterion of "clinical pregnancy" and 4.1 times according to the criterion of "live birth".

A Review: Biomechanical Aspects of the Fallopian Tube Relevant to its Function in Fertility.

The fallopian tube (FT) plays a crucial role in the reproductive process by providing an ideal biomechanical and biochemical environment for fertilization and early embryo development. Despite its importance, the biomechanical functions of the FT that originate from its morphological aspects, and ultrastructural aspects, as well as the mechanical properties of FT, have not been studied nor used sufficiently, which limits the understanding of fertilization, mechanotrasduction, and mechanobiology during embryo development, as well as the replication of the FT in laboratory settings for infertility treatments. This paper reviews and revives valuable information on human FT reported in medical literature in the past five decades relevant to the biomechanical aspects of FT. In this review, we summarized the current state of knowledge concerning the morphological, ultrastructural aspects, and mechanical properties of the human FT. We also investigate the potential arising from a thorough consideration of the biomechanical functions and exploring often neglected mechanical aspects. Our investigation encompasses both macroscopic measurements (such as length, diameter, and thickness) and microscopic measurements (including the height of epithelial cells, the percentage of ciliated cells, cilia structure, and ciliary beat frequency). Our primary focus has been on healthy women of reproductive age. We have examined various measurement techniques, encompassing conventional metrology, 2D histological data as well as new spatial measurement techniques such as micro-CT.

Features of the vagina microbiotope in patients with adenomyosis

The objective: to assess the composition of the vaginal microbiota in women of reproductive age with adenomyosis.Materials and methods. A comprehensive clinical-laboratory and instrumental prospective examination of 224 patients aged 30 to 50 years (average age – 42.0±1.8 years) with adenomyosis, who were included in the main study group, was conducted. The patients of the main group were divided into 2 subgroups depending on the form of adenomyosis – I group (diffuse form) included 106 women, II group (nodular form) – 118 persons. The control group included 84 healthy women of reproductive age with a regular ovulatory menstrual cycle and no history of gynecological diseases.Patients underwent microscopic examination of vaginal secretions, bacterioscopic examination of vaginal smears, stained according to Gram. Lactobacillus cultures were identified by polymerase chain reaction (PCR) and 16S ribosomal ribonucleic acid analysis.​Results. During the microscopic examination of the vaginal secretion, more than 15 leukocytes in the field of view were detected in 84 (37.5±3.2%) patients of both groups: in 40 (47.9±3.3%) patients of the I group and in 44 (52.1±3.3%) – II group. During the bacterioscopic examination of vaginal swabs, stained according to Gram, no gonococci and trichomonads were found in the main group. Candida fungi were detected microscopically in 158 patients (70.5±3.1%) of the main group: in 71 (66.9±4.6%) of the I group and in 87 (33.1±4.3%) of II group.Genotyping results showed that lactobacilli isolated from women with adenomyosis belonged to seven species: Lactobacillus fermentum, Lactobacillus iners, Lactobacillus gasseri, Lactobacillus amnionii, Lactobacillus jensenii, Lactobacillus crispatus, and Lactobacillus delbrueskii. The majority of lactobacilli strains have high inhibitory activity against all test strains, except for Candida albicans (39 cases, 46.4%). High adhesion to human erythrocytes was determined by 54.7% (46 cases) of the studied cultures.All lactobacilli strains were resistant to metronidazole, 83.3% (70 cases) to kanamycin, 57.1% (48 cases) to vancomycin, all strains were sensitive to roxithromycin, amoxiclav, and ampicillin. Moderate sensitivity to gentamicin and cefazolin was found in 51.9% (43 cases) of cultures, peroxide-forming activity in 80.9% (68 cases).The use of quantitative diagnostic thresholds has led to significant improvements in diagnostic performance. PCR showed 88% sensitivity and 95% specificity for Gardnerella vaginalis and 96% sensitivity and 97% specificity for Atopobium vaginae.Conclusions. It has been established that bacterial vaginosis and microorganisms associated with bacterial vaginosis are independently associated with adenomyosis. The results of the study confirmed that vaginal microorganisms, which are usually diagnosed in women with adenomyosis, ascend to the endometrium from the vagina vertically, which leads to infection of the upper parts of the genital tract.

Impact of a hypocaloric dietary intervention on antral follicle dynamics in eumenorrheic women with obesity.

Do antral follicle dynamics change in women with obesity and regular ovulatory cycles after a 6-month hypocaloric dietary intervention? After a 6-month hypocaloric dietary intervention, women with obesity and regular ovulatory cycles displayed evidence of improved antral follicle dynamics defined by the emergence of more dominant follicles, larger ovulatory follicle diameter at selection, and increased luteal progesterone concentrations compared to pre-intervention. Precise events in antral folliculogenesis must occur in order for natural and regular monthly ovulation. In healthy women of reproductive age, antral follicles are recruited for growth in a wave-like fashion, wherein a subset of follicles are selected for preferential growth, and typically, one dominant follicle culminates in ovulation. Women with obesity and regular ovulatory cycles display evidence of suppressed antral follicle development, as evidenced by fewer recruitment events, fewer selectable and dominant follicles, smaller diameter of the ovulatory follicle at selection, and a higher prevalence of luteal phase defects. While improvements in gonadotropin and ovarian steroid hormone concentrations after weight loss have been documented in eumenorrheic women with obesity, the precise impact of weight loss on antral follicle dynamics has not been evaluated. A pre-post pilot study of 12 women who participated in a 6-month hypocaloric dietary intervention. Twelve women with obesity (total body fat ≥35%) underwent transvaginal ultrasonography and venipuncture every-other-day for one inter-ovulatory interval (IOI) both before (baseline) and during the final month (Month 7) of a six-month hypocaloric dietary intervention. Participants were aged 24-34 years and had a self-reported history of regular menstrual cycles (25-35 days). Follicle number and diameter (≥2 mm) were quantified at each study visit, and individual growth profiles for all follicles ≥7 mm were determined. Blood samples were assayed for reproductive hormones. Follicle dynamics and reproductive hormone concentrations were compared pre- and post-intervention. Further, post-intervention follicle and endocrine dynamics (Month 7 IOI) were compared to an age-matched reference cohort of lean women with regular ovulatory cycles (total body fat <35%, N = 21). Participants lost an average of 11% of their original body weight with the hypocaloric dietary intervention. More dominant follicles were detected (≥10 mm) at Month 7 compared to baseline (0. 3 ± 0.4 versus 0.4 ± 0.5 follicles, P = 0.001), and ovulatory follicles were selected at larger diameters post-intervention (7.3 ± 2.0 versus 10.9 ± 2.6 mm, P = 0.007). Luteal progesterone concentrations were increased at Month 7 compared to baseline (5.3 ± 3.65 versus 6.3 ± 4.74 ng/ml, P < 0.0001). However, risk for luteal phase dysfunction as judged by the prevalence of a luteal phase length <10 days, integrated luteal progesterone levels <80 ng/ml or peak progesterone <10 ng/ml did not differ pre- versus post-intervention (all, P > 0.05). In Month 7, follicle dynamics and endocrine profiles were similar to the reference cohort across all measures. This study does not inform on the earliest stages of ovarian follicle development and is limited to providing knowledge on the later stages of antral follicle development. This study cannot fully address causation between weight loss and sustained improvements in antral follicle dynamics. The data cannot be extrapolated to comment on potential improvements in fertility and fecundity with weight loss. The small group sizes limit statistical power. The increasing prevalence of obesity necessitates an understanding of the mechanisms that underlie potential improvements in reproductive health outcomes with weight loss. Women with obesity and regular ovulatory cycles who undertook a 6-month hypocaloric dietary intervention demonstrated improvements consistent with benefits of lifestyle intervention on reproductive health even in those without overt signs of reproductive dysfunction. Potential improvements in the cellular makeup of follicles, which may underlie the restoration of normal follicle development and amelioration of subfertility, require further investigation.

Premenstrual Syndrome: Awareness and Oral Manifestations in Patients Attending Dental Hospital in Pune

ABSTRACT Fluctuations in androgenic hormonal levels are noticeable through women’s menstrual cycle. Changes in estrogen and progesterone have been shown to affect periodontium. Many women report an increase in gingival inflammation and discomfort associated with their menstrual cycle, most commonly before the menstrual period. Approximately 80% of women experience complaints of premenstrual syndrome (PMS) 7 to 10 days before menstruation. Therefore, the present study was carried out to check prevalence of PMS and its oral and periodontal manifestations in patients attending dental hospital. For the study, 100 systemically healthy women of reproductive age attending dental hospital were selected. Thorough recording of oral discomfort and associated symptoms during late luteal phase was done. Clinical parameters such as plaque index and gingival index were recorded.Thirty-seven females reported complaints suggestive of PMS. Oral changes during PMS were experienced by 59 females. Halitosis and oral ulcers were more frequent. Findings of the present study showed the possibility of influence of sex hormones on oral manifestations during premenstrual period.

Monitoring Contractility of Junctional Zone Endometrium across Menstrual Cycle Using the ElectroUteroGraph (EUG): A Clinical Evaluation

(1) Background: Abnormal uterine contractility for nonpregnant women has been associated with gynecological pathologies and infertility. The objective of this study was to evaluate the ability of a novel monitoring technique to assess the contractility of the nongravid uterus using a simple, standardized, direct, in vivo methodology during the different phases of the menstrual cycle. (2) Methods: Twenty-six healthy women of reproductive age (28–48 years) were recruited. An ElectroUteroGraph (EUG) was used to measure the electrical activity from the contractility of the junctional zone endometrium (JZE) across the menstrual cycle. Derived recordings were separated into the early proliferative (EP) (n = 10), late proliferative (LP) (n = 31), early luteal (EL) (n = 27), and late luteal (LL) (n = 12) phases of the menstrual cycle. EUG recordings were performed by inserting a flexible electrode array into the endometrial cavity. (3) Results: Waveforms that were measured from the electrode closer to the fundus (1 cm distance) were processed. The Root-Mean-Square (RMS) Voltage Amplitude (VJZE-RMS) (in μV) and the Mean Frequency (fJZE-mean) (in cycles/min) of the JZE’s electrical activity, as direct indicators of the intensity and frequency changes in the JZE’s contractions, were extracted from the recorded waveforms. There was a trend in the median values of the VJZE-RMS decreasing from the EP to the LP phase (247–158 μV). During the EL phase, an upward trend was observed (158–374 μV, p &lt; 0.05), reaching its highest value during the LL phase (374–477 μV, p &lt; 0.05) when compared to the LP phase. The fJZE-mean showed the opposite trend, increasing from 2.5 cycles/min during the EP phase to 2.96 cycles/min during the LP phase. During the EL phase, a downward trend was observed (2.96–2.37 cycles/min), continuing to fall to 1.33 cycles/min, in the LL phase, with p &lt; 0.05 when compared to the previous three phases. (4) Conclusions: The novel in vivo monitoring technique has shown clinically, for the first time, significant electrical activity differences in the different sub-phases of the menstrual cycle, recorded in a safe and painless way.

Blood oxytocin levels and the rs4686302 polymorphism of the oxytocin receptor gene in patients with adenomyosis

BACKGROUND: An in-depth study of the pathogenesis of adenomyosis and the development of new therapeutic approaches are extremely relevant. Atosiban, a competitive oxytocin receptor antagonist, may be a promising drug with a potential therapeutic effect. Oxytocin is involved in the pathogenesis of adenomyosis-associated dysmenorrhea, and there is evidence of increased expression of the oxytocin receptor (OXTR) in the myometrium in adenomyosis and the association of the OXTR gene polymorphic variant rs4686302 with oxytocin-induced myometrial contractility.&#x0D; AIM: The aim of this study was to evaluate blood oxytocin levels and the frequency of the polymorphic variants of the oxytocin receptor gene (OXTR) rs4686302 polymorphism in patients with adenomyosis and in healthy women of reproductive age.&#x0D; MATERIALS AND METHODS: The levels of oxytocin in the blood plasma were measured by competitive enzyme immunoassay (ELISA) in patients with adenomyosis (n = 56, with mean age of 37.5 ± 8.54 years), and in women without gynecological diseases (control group; n = 33, with mean age of 32.1 ± 5.40 years). The polymorphic variant rs4686302 of the OXTR gene was analyzed by PCR-RFLP analysis in patients with adenomyosis (n = 79, with mean age of 39.9 ± 7.74 years) and in control group patients (n = 49, with mean age of 37.0 ± 9.20 years). The chi-square (χ2) test was used to analyze the distribution of genotypes and alleles. Statistical data processing was performed using the Jamovi Software, Version 1.2.27 for Windows.&#x0D; RESULTS: In patients with adenomyosis, the level of oxytocin in the blood serum was significantly higher than in control group patients: 130.0 ± 27.9 pg/ml and 95.9 ± 26.7 pg/ml, respectively. The minor allele A of the OXTR gene polymorphic variant rs4686302 was significantly more common in patients with adenomyosis (28.5%) than in women in the control group (13.3%) and in the general sample (11–15% according to the 1000 Genomes Project). The odds of developing adenomyosis in patients with the presence of the A allele (the G/A and A/A genotypes) were 2.44 times higher compared to patients with the G/G genotype (OR 2.44, 95% CI 1.13–5.28).&#x0D; CONCLUSIONS: The data obtained suggest the participation of oxytocin and its receptor in the pathogenesis of adenomyosis and requires further research in this direction.

The potential of survivin as a non-invasive diagnostic marker for endometriosis in patients with type 1 diabetes mellitus

BACKGROUND: According to international data, about 5-10% of women of reproductive age suffer from this disease, while in women with chronic pelvic pain or infertility the incidence ranges from 35% to 50%. At the same time, women of reproductive age diagnosed with diabetes mellitus type 1 may also suffer from endometriosis, but asymptomatic or atypical in the initial stages of the disease, which varies considerably in duration, may be the cause of untimely diagnosis. Existing diagnostic methods in the form of bimanual examination, ultrasound, MRI, laparoscopic surgery, and even histologic verification do not allow to exclude with certainty the presence of the disease.&#x0D; AIM: The aim of this study was to investigate the prevalence and characteristics of endometriosis among patients with type 1 diabetes mellitus to develop a diagnostic prognostic model.&#x0D; MATERIALS AND METHODS: We carried out a retrospective analysis of medical records from the Gynecological Unit of the Second Department of Gynecology and Endocrinology and the Scientific Advisory Department of D.O. Ott Research Institute of Obstetrics, Gynecology, and Reproductive Medicine, St. Petersburg, Russia for the period of 2010–2021. The study cohort included cases of endometriosis in patients with type 1 diabetes mellitus recorded in inpatient or outpatient medical histories. Clinical characteristics of the prevalence of endometriosis in women with type 1 diabetes mellitus were based on an analysis of 2316 medical records in this patient group. The prospective cohort of the case-control study included 137 patients and involved the evaluation of survivin levels in serum on days 5–7 of the menstrual cycle in four study groups: type 1 diabetes mellitus in combination with endometriosis, endometriosis, type 1 diabetes mellitus, and healthy women of reproductive age. Additionally, we examined the gynecological history of patients. Statistical processing of the data obtained and predictive modeling were performed using a binary logistic regression analysis.&#x0D; RESULTS: The prevalence of endometriosis among patients with type 1 diabetes mellitus was 1.11%. Risk indicators for the presence of endometriosis were determined based on risk factor values for patients with or without type 1 diabetes mellitus. Patient groups with a probability of having endometriosis exceeding 50% were identified, requiring diagnostic and therapeutic measures aimed at timely initiation of therapy.&#x0D; CONCLUSIONS: Predicting the likelihood of endometriosis presence will enable timely preventive and therapeutic measures aimed at improving the patient’s quality of life.

Changes of uterine morphology and endometrial T2 signal intensity in the fibrotic repair secondary to endometrial injury

Objective: To investigate the value of uterine morphological parameters and endometrial T2 signal intensity (T2-SI) in evaluating the degree of the fibrotic repair secondary to endometrial injury. Methods: From Sep. 2018 to Feb. 2023, this study prospectively enrolled 29 patients with fibrotic repair secondary to severe endometrial injury (severe group), 17 patients with fibrotic repair secondary to mild to moderate endometrial injury (mild to moderate group), and 40 healthy women of reproductive age (control group) in Nanjing Drum Tower Hospital. The length of uterine cavity (LUC), length of cervix and isthmus (LCI), width of upper uterine cavity (WUUC) and width of lower uterine cavity (WLUC) were measured using magnetic resonance imaging. T2-SI of endometrium and subcutaneous fat of buttocks were measured, and endometrial normalized T2-SI (nT2-SI; T2-SI of endometrium/T2-SI of subcutaneous fat of buttocks) was calculated. Statistical analyses of data were performed using one-way analysis of variance, Mann-Whitney U test, intraclass correlation coefficient, Spearman rho test, area under the receiver operating characteristic curve (AUC). Results: LUC, WUUC, WLUC and endometrial nT2-SI of severe group [(19.7±3.5) mm, (26.9±6.4) mm, (7.9±1.4) mm, 0.73±0.11, respectively] were significantly lower than those of the control group (all P<0.01), while LCI and WUUC/LUC [(51.3±7.3) mm and 1.38±0.34] were significantly higher than those of the control group (all P<0.001). LUC and WLUC of severe group were significantly lower than those of mild to moderate group [(32.4±5.1) mm and (8.8±1.2) mm; all P<0.05], while LCI and WUUC/LUC were significantly higher than those of mild to moderate group [(41.8±8.6) mm and 0.94±0.16; all P<0.001]. LUC and endometrial nT2-SI of mild to moderate group were significantly lower than those of the control group [ (32.4±5.1) vs (35.3±3.5) mm, 0.68±0.13 vs 0.80±0.12; all P<0.01]. LUC, WUUC, WLUC and endometrial nT2-SI were significantly negatively correlated to the degree of the fibrotic repair secondary to endometrial injury (Spearman rho:-0.794, -0.441, -0.471 and -0.316, respectively; all P<0.05), while LCI and WUUC/LUC were significantly positively correlated to the degree of the fibrotic repair secondary to endometrial injury (Spearman rho: 0.481 and 0.674, respectively; all P<0.05). LUC and WUUC/LUC showed high value in distinguishing severe group from the control group or mild to moderate group (all AUC>0.9, all P<0.001). Conclusion: As noninvasive and quantitative biomarkers, uterine morphological parameters and endometrial nT2-SI could evaluate the degree of the fibrotic repair secondary to endometrial injury.

The Prevalence of Bacterial Vaginosis among Infertile Iraqi Women and Subsequent ICSI outcome

The vaginal microbial makeup has a substantial impact on women's health. The typical vaginal microbial profile in healthy women of reproductive age comprises aerobic, facultatively anaerobic, as well as obligately anaerobic organisms. However, the optimal vaginal microbiota is dominated by lactobacilli and is thought to defend against pathogenic microbial colonization and infection by producing lactic acid, antimicrobial metabolites, and lowering immune system activation. Recent research has come up with the term "molecular bacterial vaginosis (BV)" to describe non-optimal vaginal microbiota that is low in Lactobacillus species (spp.) and has a lot of facultative and absolute anaerobic bacteria specifically Gardnerella vaginalis. In the context of IVF, BV has been linked to infertility. The study comprised forty-six women to explore the vaginal and follicular microbiota of asymptomatic infertile Iraqi women starting an ICSI trial. At the time of ova pick-up, a high vaginal swab and follicular fluid were acquired from each instance for DNA extraction to test for the presence of microorganisms by the use of a real-time PCR special commercial kit. In conclusion, molecular technologies have offered a more thorough view into the vaginal microbiota, which may explain why vaginal dysbiosis shifts during the ICSI-ET treatment. Even though the majority of women have no clinically visible infection, the fact is that they have an aberrant vaginal micro-ecology profile. Nevertheless, isolating microorganisms from follicular fluid did not reduce the likelihood of fertilization or the pregnancy rate during ICSI cycles.

Assessment of key parameters of normal uterus in women of reproductive age

Currently, the precise and detailed anatomical data of the normal uterus, especially the myometrium thickness in various parts of the uterus, are lacking. This study aims to provide normal references for uterine size in healthy reproductive-aged Chinese women to facilitate the application of hysteroscopic surgery. A total of 298 women of reproductive age with normal uterine were included. Parity was significantly correlated with uterine measurements (P < 0.05), and age impacted several measurements (P < 0.05). At each uterine site examined, the myometrium was thinner in nulliparous women than in parous or primiparous women (P < 0.001). Similarly, the extrauterine measurements for parous or primiparous women were larger than those for nulliparous women. Weight affected some external measurements but not myometrial thicknesses, while height did not affect uterine measurements (P > 0.05). There was a positive correlation between body mass index (BMI) and extrauterine measurements as well as myometrial thickness (P < 0.05). The mathematical model of the uterine size for women of reproductive age was constructed stratified by parity. The study is the first to provide a detailed statistical description of the accurate anatomical parameters of the uterus in Chinese reproductive-aged women and has great significance for improving the safety and effectiveness of hysteroscopic surgery for patients.

OR09-05 GPBAR1- Understanding Its Function In The Secretory Endometrium

Abstract Disclosure: M. Saad-Naguib: None. P. Timmins: None. L. George: None. C. Samuels: None. N. Douglas: None. A.V. Babwah: None. Every successful pregnancy relies on implantation of an embryo into a receptive uterine endometrium. While implantation failure accounts for 50% of pregnancy failures, it remains the least understood aspect of pregnancy. In the mid-secretory (MS) phase of the menstrual cycle, under the influence of progesterone and cAMP, fibroblasts decidualize, a critical requirement for implantation. Decidualization involves the differentiation of stromal fibroblasts into secretory epithelioid cells that contribute to the formation of the decidua, the support of the pregnancy prior to placentation. A defective decidua can lead to implantation failure, but if implantation occurs, it could compromise placenta formation and function. Several studies have demonstrated the importance of G protein-coupled receptors (GPCRs) in mouse endometrial receptivity and decidualization. GPCRs are transmembrane signaling molecules that are ubiquitously expressed in the body and regulate almost every cellular and physiological process. They are major pharmaceutical targets, with 35% of all the drugs approved by the US FDA targeting GPCRs. To identify novel GPCR regulators of embryo implantation, we conducted bulk RNA sequencing of the human endometrium at the periovulatory (PO) and mid-secretory (MS) phase in natural menstrual cycles in healthy women of reproductive age and observed that genes encoding 11 GPCRs, not previously reported to regulate implantation, were differentially expressed between these two time points. Among these was the gene encoding the G protein-coupled bile acid receptor 1 (GPBAR1), and this was upregulated 4.6-fold in the MS vs PO phase. Single cell RNA sequence analysis showed that within the human endometrium, GPBAR1 mRNA expression is mostly and strongly localized to stromal fibroblasts. Upon activation by secondary bile acids, GPBAR1 couples to Gαs leading to an increase in intracellular cAMP levels. We hypothesize that in the MS endometrium, upon ligand binding, GPBAR1 produces cAMP and induces human endometrial stromal cell (HESC) decidualization. This hypothesis is being tested in vitro using primary HESCs. Interestingly, in the pregnant mouse, GPBAR1 mRNA is barely expressed at the implantation site on E7.5, and therefore unlikely plays a role in stromal cell decidualization in the mouse. Whether Gpbar1 is expressed in the pregnant mouse endometrium prior to implantation and plays a role in regulating endometrial receptivity is being investigated. Overall, our studies have uncovered a GPCR, that to our knowledge, has not been previously described in the human endometrium. Our data show that the expression of this GPCR is upregulated at the time of endometrial stromal cell decidualization, and therefore it might regulate decidualization and/or be required for decidual function in women. These possibilities are being examined. Presentation: Friday, June 16, 2023

Coagulation Status in Women with a History of Missed Abortion.

The purpose of this study assess the status of coagulation function in a large series of reproductive-age women with a history of missed abortion in China. Likewise, we want to explore the association between coagulation and missed abortions, in order to evaluate whether they could be used as early predictive factors for missed abortions. A total of 11,182 women who suffered from missed abortion from Peking University Third Hospital and 5298 healthy age-matched reproductive-age women were enrolled in our study. Coagulation function tests (prothrombin time, activated partial thromboplastin time), fibrinolysis status detection (fibrinogen, D-Dimer), anticoagulation function tests (protein C, protein S and antithrombin III), and lupus anticoagulants (LAC) were examined. In addition, platelet counts were detected by automated hematology analyzer. Platelet aggregation (PAgT) was tested by light transmission aggregometry (LTA). Compared with healthy reproductive-age women, the level of D-Dimer, dRVVT-R, PC, PAgT, and platelet count was higher, and the antithrombin III (AT-III) activity was lower in women with a history of missed abortion. (P < 0.05). A total of 13.1% patients with a history of missed abortion were positive for LAC, and platelet aggregation rates were increased in 47.4% patients. Moreover, multivariate logistic regression analysis showed that D-Dimer, dRVVT-R, AT-III, PC, and PAgT had significant predictive value for missed abortion. In addition, a model based on coagulation function tests for predicting missed abortion was developed. These findings provide evidence of hypercoagulability in patients with a history of missed abortion. Lupus anticoagulant, PAgT, and D-Dimer were the strongest predictors of missed abortion.was to.

Prevalence, Regional Variations, and Predictors of Overweight, Obesity, and Hypertension Among Healthy Reproductive-Age Indian Women: Nationwide Cross-Sectional Polycystic Ovary Syndrome Task Force Study.

A clear understanding of the anthropometric and sociodemographic risk factors related to BMI and hypertension categories is essential for more effective disease prevention, particularly in India. There is a paucity of nationally representative data on the dynamics of these risk factors, which have not been assessed among healthy reproductive-age Indian women. This cross-sectional polycystic ovary syndrome (PCOS) task force study aimed to assess the anthropometric and sociodemographic characteristics of healthy reproductive-age Indian women and explore the association of these characteristics with various noncommunicable diseases. We conducted a nationwide cross-sectional survey from 2018 to 2022 as part of the Indian Council of Medical Research-PCOS National Task Force study, with the primary aim of estimating the national prevalence of PCOS and regional phenotypic variations among women with PCOS. A multistage random sampling technique was adopted, and 7107 healthy women (aged 18-40 years) from 6 representative geographical zones of India were included in the study. The anthropometric indices and sociodemographic characteristics of these women were analyzed. Statistical analysis was performed to assess the association between exposure and outcome variables. Of the 7107 study participants, 3585 (50.44%) were from rural areas and 3522 (49.56%) were from urban areas. The prevalence of obesity increased from 8.1% using World Health Organization criteria to 40% using the revised consensus guidelines for Asian Indian populations. Women from urban areas showed higher proportions of overweight (524/1908, 27.46%), obesity (775/1908, 40.62%), and prehypertension (1008/1908, 52.83%) categories. A rising trend of obesity was observed with an increase in age. Women aged 18 to 23 years were healthy (314/724, 43.4%) and overweight (140/724, 19.3%) compared with women aged 36 to 40 years with obesity (448/911, 49.2%) and overweight (216/911, 23.7%). The proportion of obesity was high among South Indian women, with 49.53% (531/1072) and 66.14% (709/1072), using both World Health Organization criteria and the revised Indian guidelines for BMI, respectively. BMI with waist circumference and waist-to-height ratio had a statistically significant linear relationship (r=0.417; P<.001 and r=0.422; P<.001, respectively). However, the magnitude, or strength, of the association was relatively weak (0.3<|r|<0.5). Statistical analysis showed that the strongest predictors of being overweight or obese were older age, level of education, wealth quintile, and area of residence. Anthropometric and sociodemographic characteristics are useful predictors of overweight- and obesity-related syndromes, including prehypertension, among healthy Indian women. Increased attention to the health of Indian women from public health experts and policy makers is warranted. The findings of this study can be leveraged to offer valuable insights, informing health decision-making and targeted interventions that mitigate risk factors of overweight, obesity, and hypertension.

Salivary microbiome of healthy women of reproductive age.

The salivary microbiome has been proven to play a crucial role in local and systemic diseases. Moreover, the effects of biological and lifestyle factors such as oral hygiene and smoking on this microbial community have already been explored. However, what was not yet well understood was the natural variation of the saliva microbiome in healthy women and how this is associated with specific use of hormonal contraception and with the number of different sexual partners with whom microbiome exchange is expected regularly. In this paper, we characterized the salivary microbiome of 255 healthy women of reproductive age using an in-depth questionnaire and self-sampling kits. Using the large metadata set, we were able to investigate the associations of several host-related and lifestyle variables with the salivary microbiome profiles. Our study shows a high preservation between individuals.

Use of serum copper and zinc levels in the diagnostic evaluation of endometrioma and epithelial ovarian carcinoma.

The aim of this study is to evaluate serum copper (Cu) and zinc (Zn) levels in patients with epithelial ovarian cancer and endometrioma. We included 21 epithelial ovarian cancer patients, 47 endometrioma patients, 31 healthy women of reproductive age, and 10 healthy women in menopause. Cu and Zn levels and Cu/Zn ratios were compared. In the endometrioma group, Cu levels (P = 0.04) and Cu/Zn ratio (P &lt; 0.01) were higher, while Zn levels (P &lt; 0.01) were lower compared to the control group. The threshold value of 1.15 with 62% sensitivity and 61% specificity was calculated for the Cu/Zn ratio using the ROC curve (AUC = 0.688; P = 0.005). In the ovarian cancer group, Cu levels (P ≤ 0.01) and Cu/Zn ratio (P = 0.02) were higher, whereas Zn levels (P ≤ 0.02) were lower compared to the control group. The Cu/Zn ratio threshold value of 1.37 was calculated with 76% sensitivity and 90% specificity (AUC = 0.829; P = 0.004). The Zn level was lower (P = 0.02), and the Cu/Zn ratio was higher (P = 0.01) in the ovarian cancer group compared to the endometrioma group. The threshold value of the Cu/Zn ratio for ovarian cancer could be determined with a specificity of 90%, whereas the sensitivity and specificity of the Cu/Zn ratio for endometrioma were low.

Pathology of cervical epithelium in women with various forms of infertility

Failure to conceive in a couple, that does not prevent fertilization for 12 months or more, is defined as infertility. This diagnosis is special one both because of the social component and of the involvement of two persons in it, as well as because of polyetiological factors. Pathology of the cervical epithelium is a common problem among women of reproductive age. In patients with infertility, it has its own significance as a factor for fertility disorders. In addition, there is a possible influence of different methods of treatment of pathology of the cervical canal on the course of pregnancy that occurred after treatment.The objective: to study the prevalence of cervical pathology in patients with various types of infertility.Materials and methods. The results of liquid cytology and human papillomavirus (HPV) testing were analyzed in 416 women, who were divided into four groups: I group included 108 patients with infertility associated with anovulation, II group – 101 patients with infertility of tubal origin, III group – 102 women with a male infertility factor in marriage, IV group – 105 women who applied for a preventive examination.Results. The general frequency of early cervical lesions of severity various degrees was differed significantly in the groups of the examined persons – from the lowest 25.9% in the group of patients with infertility associated with anovulation, and 35.2% in the group of women who applied for a preventive examination, to 50.9 % among women with infertility of tubal origin and 52.4% – in the group with a male infertility factor.In the last two mentioned groups, the frequency of severe intraepithelial lesions (7.8% and 7.9%, respectively) was higher than in the other groups, where it was established at a level of no more than 1.5%. A higher rate of HPV infection was also established in the groups infertility of tubal origin – 68.6%, male infertility – 63.4%, while in the group of patients with anovulation infertility its prevalence was at the level of 35.1%, which does not exceed the rate of healthy women in control group – 25.7%.Conclusions. 1. Patients with infertility of tubal origin and male factor infertility have a higher frequency of early cervical changes (50.9% and 52.9%, respectively) than healthy women of reproductive age (35.2%). 2. In cases of tubal and male factor infertility, the frequency of HPV infection is higher than the rate of the cervical epithelium lesions detected by the cytological method (68.6% and 63.4%, respectively), which allows us to recommend the HPV test to include in the list of mandatory examinations during preparation for the program of assisted reproductive technologies.
