Background: Endometrial cancer (EC) has a high latency, making prognosis difficult to predict. Cancer antigen 125 (CA125) is not specific as a tumour marker for EC; however, complete blood count (CBC) inflammatory markers are associated with prognosis in various malignancies. Thus, this study investigated the value of CBC inflammatory markers combined with CA125 levels in predicting the prognosis of patients with EC.

Methods: In this study, 517 patients with EC were recruited between January 2015 and January 2022, and clinical characteristics, CBC inflammatory markers, and CA125 levels were assessed. Differences in each index at different EC stages and the correlation between the index and EC stage were analysed, and the influence of the index on EC prognosis was evaluated.

Results: Platelet distribution width (PDW) levels were significantly lower in patients with advanced EC than in those with early EC, whereas the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and CA125 levels were significantly higher in patients with advanced EC (all P < 0.05). ROC curve and multivariate logistic regression analyses indicated that decreased PDW and increased CA125 levels were independent risk factors for EC staging progression. In addition, multivariate Cox regression analysis showed that the combination of low PDW and high CA125 (PDW + CA125 = 2) was an independent prognostic factor of survival in EC patients. Kaplan-Meier survival analysis indicated that patients with low PDW and high CA125 had worse overall survival.

Conclusions: The PDW and CA125 score may be an independent prognostic factor for postoperative overall survival in patients with EC and a useful marker for predicting the prognosis of these patients.

Background: Prediabetes (PD) is associated with intermediate hyperglycaemia, dyslipidaemia, reduced nitric oxide (NO) bioavailability and moderate hypertension. All these factors are risk factor for preeclampsia (PE). However, the effects of the PD on placental function have not been shown. Accordingly, this study sought to investigate a possible link between maternal PD and the risk of developing PE.

Methods: Pregnant female Sprague-Dawley rats (N = 18) were divided into normal, preeclamptic and prediabetic groups (n = 6 in each group) to study the effects of maternal PD on placenta function over the period of 19 days. Blood glucose and blood pressure were measured on gestational day (GND) 0, 9 and 18. Placental vascular endothelial growth factor (VEGF), placenta growth factor (PlGF) and soluble fms-like tyrosine kinase 1 (sFlt-1) mRNA expression were measured terminally. Data were analysed using ANOVA followed by the Tukey-Kramer post hoc test. Values of p < .05 were used to indicate statistical significance.

Results: Maternal PD and PE significantly increased blood glucose, decrease NO concentration and increase in MAP by comparison to the normal pregnant control group. Maternal PD significantly decreased VEGF, PlGF mRNA expression with a slight increase in sFlt-1 mRNA expression comparison to the normal pregnant control group.

Conclusions: Maternal PD is associated with placental dysfunction due to impaired glucose handling, endothelial dysfunction and an imbalance in angiogenic and antiangiogenic factors. Therefore, maternal PD is a risk factor of PE.

Background: This study aimed to determine the effect and mechanism of the Decoction of Yougui Wan combined with Wuzi Yanzong Wan (DYWWYW), a traditional Chinese herbal formula, in a mouse model with thin endometrium induced by 95% ethanol.

Methods: Thin endometrium mice were treated with progynova (0.002 mg) as well as a low and high dose of DYWWYW (0.05 and 0.5 mL DYWWYW, respectively, diluted in 2 mL normal saline). Western blotting and qRT-PCR analyses were performed to determine the protein and mRNA expression levels, respectively, of integrin αγβ3 and leukaemia inhibitor factor (LIF) in uterus tissues. Serum oestradiol and progesterone concentrations were determined via ELISA. The remaining thin endometrium mice were mated with male mice, and the number of embryos implanted in the different groups was calculated.

Results: A high dose of DYWWYW effectively ameliorated the injury of endometrium caused by 95% ethanol. The levels of oestradiol, progesterone, αγβ3 and LIF in thin endometrium mice treated with a high dose of DYWWYW were also significantly elevated. Additionally, a high dose of DYWWYW remarkably increased the number of embryo implantations in mice with thin endometrium.

Conclusion: DYWWYW has improvement effects on thin endometrium by elevating the levels of endogenous oestradiol, progesterone, αγβ3, and LIF in a mouse model.

Background: Cervical cancer survivors can experience vaginal length shortening, vaginal stenosis, vaginal elasticity deterioration, sexual frequency reduction and sexual dysfunction. This prospective, uncontrolled, monocentric clinical interventional study aimed to evaluate the effect of vaginal dilation therapy on vaginal condition and sexual function of cervical cancer survivors who had not received timely vaginal dilation.

Methods: A total of 139 patients completed the study. They received 6 months of vaginal dilation therapy. We evaluated their vaginal elasticity, vaginal diameter, vaginal length and sexual function before and after vaginal dilation therapy. Their vaginal conditions were evaluated by customised vaginal moulds, and the sexual function was assessed by female sexual function index. The SPSS 25 software was used to analyse all the data.

Results: Age, vaginal diameter and sexual intercourse frequency before diagnosis were significantly associated with female sexual dysfunction of the patients after cancer treatment. Vaginal dilation therapy improved vaginal stenosis, vaginal length and sexual function in all the patients; however, the vaginal elasticity and incidence of sexual dysfunction did not improve significantly. Sexual intercourse frequency before diagnosis, vaginal elasticity, time interval from last treatment and treatment modalities were significantly associated with the change in female sexual function index score before and after vaginal dilation therapy. Patients with a time interval from the last treatment less than 24 months or those who had moderate or good vaginal elasticity, benefitted more from vaginal dilatation therapy.

Conclusions: Cervical cancer survivors who had not received timely vaginal dilation still benefitted from vaginal dilation therapy, irrespective of the treatment methods they received. Moreover, vaginal dilation therapy should be performed as early as possible after cervical cancer treatment.

Background: Primary amenorrhoea (PA) refers to an ailment when adolescent girls do not attain menarche naturally. It is one of the most common gynaecological disorders specified. Chromosomal abnormalities play a pivotal role in PA. Cytogenetic analysis is an indispensable diagnostic tool to determine the abnormality of the chromosome. In an emerging country like India, cytogenetic analysis is at a nascent stage. There are very few studies on Cytogenetics present in eastern India, including West Bengal. In rural and suburban areas PA sufferers often experience late diagnosis and struggle to access suitable curative management. The aim of the study is to evaluate the various types of chromosomal abnormalities in patients suffering from PA for accurate, better management of the same and further counselling.

Methods: A total of 40 PA cases were referred by obstetricians and gynaecologists to the Department of Genetics of Nirnayan Health Care, Kolkata. To screen the chromosomal abnormalities, human leukocyte culture was accomplished with their peripheral venous blood followed by G-banding and then karyotyping was executed according to ISCN-2020.

Result: Out of 40 patients, 29 were normal among which 46,XX was found in 70% cases (n = 28) and 46,XX,9qh + in 2.5% (n = 1). The remaining 11 showed different types of abnormalities. 45,X was found in 10% (n = 4), 46,X,i(X)(q10) in 2.5% (n = 1), 46,X,del(X)(p11.2) in 2.5% (n = 1), 46,X,del(X)(p22.1) in 2.5% (n = 1), 46,X,del(X)(q24) in 2.5% (n = 1), 46,XY in 2.5% (n = 1), mos 45,X[22]/46,Xi(X)(q.10)[8] in 2.5% (n = 1) and mos 45,X[16]/46,XY[14] (2.5%) in 2.5% (n = 1).

Conclusion: This study indicates the importance of chromosomal study which must be included in early diagnosis of PA. Karyotyping at the appropriate phase of life will not only help in the judicial management of this disorder but will also give young girls a better lifestyle.

Background: Lichen sclerosus (LS) is a chronic, inflammatory disease of the genital and extra genital skin, causing pruritus, soreness, pain and dyspareunia. The aim of this study was to investigate whether Low Level Laser Therapy (LLLT) can improve the quality of life in women with Lichen sclerosus (LS) and insufficient topical treatment.

Methods: In a descriptive prospective observational study conducted between 02.01.2016 and 08.01.2018, we included 100 women with LS with insufficient topical treatment because of poor response of symptoms. All participants received ten LLLT treatments (808 nm and 500 mW) over a period of 8 weeks. The first four treatments were planned as two treatments per week. The remaining six treatments were planned as once a week. A Danish health-related quality of life tool (HRQoL test) monitored the effect.

Results: A total of 94 patients completed the study, median age of 62 [InterQuartile Range 53-69]. There was a statistically significant improvement in seven of the eight domains of the HRQoL test after ten LLLT. We found the results of DoloTest to be statistically significant in all of the groups except for smoking (p < 0.094).

Conclusions: LLLT treatment can improve the quality of life in women with LS.

Background: Pelvic organ prolapse (POP), characterised by the downward displacement of pelvic organs, is a prevalent disorder that affects adult women. This study explored the therapeutic potential of PX-478, a selective hypoxia-inducible factor-1α (HIF-1α) inhibitor, in a murine POP model.

Methods: A murine POP model was established through ovariectomy, mimicking oestrogen deprivation. Fifteen C57BL/6J mice were randomly assigned to control, POP, and PX-478 groups. PX-478, targeting HIF-1α, was administered intravaginally. The analysis of fibroblasts, macrophage and inflammation was performed through Masson staining, immunofluorescence, and ELISA. Collagen distribution was assessed using Sirius Red staining. Expression levels of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMP-1) were determined through immunohistochemistry and western blot. Fibroblast proliferation and apoptosis were evaluated by CCK-8 assay and flow cytometry.

Results: PX-478 treatment significantly reduced vaginal length, indicating a therapeutic effect on POP severity. Masson staining revealed reduced fibrotic changes and collagen disruption in PX-478-treated mice. Immunofluorescence showed increased fibroblast markers (Vimentin, α-SMA) and collagen fibres by PX-478. Sirius Red staining indicated PX-478 mitigated damage to Type I and Type III collagen fibres. PX-478 significantly reduced MMP-2 and MMP-9 expression while increased TIMP-1. In macrophages, PX-478 decreased M1 and M2 markers (CD80, CD206) and IL-18 secretion. Fibroblasts exhibited increased proliferation, reduced apoptosis, and altered MMP/TIMP expression under PX-478 influence.

Conclusion: PX-478 demonstrates a therapeutic potential in the mice POP model. It reduces vaginal length, attenuates fibrosis, and modulates collagen synthesis. Its immunomodulation is evident through reduced M1 and M2 macrophages and suppressed IL-18 secretion.

Background: In the classification of premenstrual disorders (PMDs), premenstrual exacerbation (PME) is listed as one of the variants of PMDs, along with core PMD. However, the incidence of PME and its impact on mental health and quality of life have not been investigated. Therefore, we investigated the proportion of PME among women seeking treatment for premenstrual symptoms in Japan and compared the levels of anxiety, depression and quality of life between women with PME and those with core PMD.

Methods: Women who presented to the Department of Obstetrics and Gynaecology of a single institute for treatment of premenstrual symptoms and were diagnosed with PMDs using patient diaries were included in the study. Based on the diagnosis, patients were divided into two groups (core PMD and PME) and their responses to a questionnaire on mental health and quality of life at the first visit were analysed.

Results: A total of 32 women were diagnosed with PMDs (22 with core PMD and 10 with PME). All underlying medical conditions in women with PME were psychiatric disorders. There were no significant differences in various factors between the two groups. In terms of mental health, the PME group had higher levels of anxiety and depression than the core PMD group. Regarding quality of life, the PME group had lower scores than the core PMD group in all domains except physical and social functioning.

Conclusions: Patients seeking treatment for premenstrual symptoms included many PME. Women with PME were more anxious and depressed than those with core PMD, and their quality of life was low in both physical and psychological domains. Patients with PME should be diagnosed and treated more appropriately.

Background: The primary objective of this study was to assess the effect of fasting during Ramadan on maternal oxidative stress levels and foetal development; pregnant women with uncomplicated, singleton pregnancies in the second trimester.

Methods: During the month of Ramadan, 23 March 2023 to 20 April 2023, 50 fasting and 50 non-fasting healthy pregnant women were enrolled in this prospective study. The fasting hours were about 14 h per day in that season. Pregnant women in the second trimester were enrolled in the study. Total antioxidant status (TAS), total oxidant status (TOS) and the oxidative stress index (OSI) were measured from maternal serum samples taken on a fasting day at the end of Ramadan. To evaluate the impact of Ramadan on the foetus, Doppler ultrasonography was performed in the beginning and then at the end of Ramadan in all participants and was used for the following measurements: Increase of biparietal diameter, femur length, estimated foetal body weight, amniotic fluid index and umbilical artery systolic/diastolic ratio. To discern differences between distinct cohorts, independent t-tests and Mann-Whitney's U-tests were employed based on the data distribution. A p value threshold of less than .05 was established to determine statistical significance.

Results: TAS level was found to be significantly lower in the group that fasted for more than 15 days compared to the non-fasting group that did not fast (p = .003), but no significant differences were found between the groups in terms of TOS and OSI (p < .05). Obstetric ultrasound parameters showed no significant differences between the two groups (p < .05).

Conclusions: The present study suggests that fasting during the second trimester of pregnancy does not substantially impact maternal or foetal health, as indicated by most oxidative stress markers and foetal parameters studied. However, the observed reduction in the TAS levels in the fasting group warrants further investigation.
