Fetomaternal outcomes in vaginal discharge during pregnancy: A prospective comparative study

Background: Vaginal discharge (VD) is a common symptom in women during the reproductive period, especially during pregnancy. Pathological VD during pregnancy is an important public health concern because it has a sociopsychological impact on women and influences fetomaternal outcomes. Aims and Objectives: The study aims to estimate the prevalence of pathological discharge in pregnant women. The study also focuses on the demographic profile and various risk factors associated with pathological VDs and their consequences on fetal and maternal health. Materials and Methods: A prospective observational study was conducted in the Department of Obstetrics and Gynecology in a tertiary care center in Northern India. A total of 150 pregnant women with complaints of VD in the second and third trimesters with confirmation on speculum examination were recruited and evaluated for the etiology of discharge. Patients were followed until delivery and data regarding fetomaternal outcomes was collected. Results: The prevalence of pathological VD among enrolled women was 39.33% and various etiologies were candidiasis (15.33%), bacterial vaginosis (10.66%), aerobic vaginitis (8.67%), and trichomoniasis (4.67%). These infections were significantly related to pre-term delivery and pre-term pre-labor rupture of membranes. Furthermore, the incidence of prematurity, and low birth weight neonates requiring neonatal intensive care unit care was significantly high in babies born to mothers with pathological VD. Conclusion: Vaginal infections affect both maternal and neonatal health, thus, increasing the likelihood of poor perinatal outcomes. Hence, we propose that routine screening for pathological VD for all pregnant women should be introduced into standard antenatal care.

Connecting the dots: Exploring the relationship between menstrual hygiene and bacterial vaginosis in eastern India

ABSTRACT Introduction: Menstruation is a normal physiological event that takes place in a rhythmic fashion during the reproductive period of a woman. Menstrual hygiene management (MHM) practices differ and depend on the individual’s socioeconomic status, local traditions and beliefs, and access to water and sanitation resources. Insufficient and incorrect information regarding menstruation and lack of knowledge and awareness leads to poor personal hygienic practices, which further leads to many infections. Bacterial vaginosis, the most common RTI, is characterized by an alteration in the vaginal micro biome with a decline in hydrogen peroxide producing Lactobacillus colonization and an overgrowth of facultative anaerobic bacteria like Gardnerella spp., Mobiluncus spp., etc. Aims: The primary objective of the study was to find out the association of bacterial vaginosis with menstrual hygiene practices. The secondary objective was to determine the prevalence of bacterial vaginosis among patients presenting with vaginal discharge to the outpatient department of a tertiary care hospital. Methods: Women in the reproductive age group 18-45 years having regular menstrual cycles were included in the study. Participants were enquired for sociodemographic data, menstrual hygiene practices and symptoms of abnormal vaginal discharge. High vaginal swab was collected for the symptomatic patients and sent to investigate for presence of bacterial vaginosis. Results and observation: The prevalence of BV was found to be 13% among symptomatic patients presenting with abnormal vaginal discharge. Apart from abnormal discharge, itching and burning sensation was also seen to have a positive association with bacterial vaginosis (p < 0.001). The women who used clothes as absorbent were more prone to develop BV than women using sanitary pad. The other parameters to have positive association with BV were decreased frequency of taking body bath. Unsatisfactory sanitation of latrine was found to be strongly associated with BV after adjusting for confounders. Conclusion: In conclusion, the result of this study provided a strong association between poor MHM practices with BV.

WITHDRAWN: Cervical pessary versus vaginal progesterone in individuals with a singleton pregnancy and a short cervix: a randomized controlled trial

For asymptomatic individuals with a singleton pregnancy and a short cervix, vaginal progesterone significantly decreases the risk of PTB and improves perinatal outcomes. Cervical pessary is another option that has been evaluated with inconclusive results. There is; however, a lack of head-to-head comparisons between pessary and vaginal progesterone in this high risk population. This randomized controlled trial (RCT) aims to compare the effectiveness of pessary and vaginal progesterone for the prevention of PTB in individuals with a singleton pregnancy and a CL ≤25 mm. We conducted an open-label, multi-center, RCT (NCT04300322) at three hospitals in Vietnam. Asymptomatic individuals with a singleton pregnancy and a CL ≤25mm (at 16 to 22 weeks) were randomized (1:1 ratio) to receive either an Arabin® cervical pessary or 200-mg vaginal progesterone daily. Primary outcome was PTB <37 weeks of any cause. Secondary outcomes were maternal and neonatal complications. We planned to recruit 804 women to assess a 10% absolute risk reduction in PTB <37 weeks (alpha-error 0.05, power 80%, 5% lost to follow-up). In view of the potential harm of pessary on perinatal mortality and PTB <28 weeks reported recently in two recent trials, our study was halted on June 2023. Analysis was by intention-to-treat. Between May 2020 and May 2023, we randomized 301 participants to pessary (N=150) or vaginal progesterone (N=151). Seven participants withdrew consent and 13 were lost to follow-up, resulting in 281 participants available for analysis (pessary group N=139; vaginal progesterone group N=142). The primary outcome, any PTB <37 weeks rate, occurred in 15.1% in the pessary group versus 14.1% in the vaginal progesterone group (RR 1.07; 95% CI, 0.61 to 1.9). PTB <28 weeks and perinatal death rates were higher in the pessary group, although these differences did not reach statistical significance (7.9% versus 4.2%, RR 1.87; 95% CI, 0.71 to 4.9 and 4.3% versus 2.8%, RR 1.5; 95% CI, 0.34 to 9.2; respectively). Vaginal discharge was significantly more frequent in the pessary group. In this prematurely halted RCT involving individuals with a singleton pregnancy and a CL ≤25 mm, neither cervical pessary nor vaginal progesterone was found to be superior in the prevention of PTB <37 weeks. However, vaginal progesterone was associated with non-significantly lower rates of PTB <34, <28 weeks and perinatal death.

Development of two step reverse transcription droplet digital PCR (RT-ddPCR) for simultaneous identification of saliva and semen

Determination of the type of body fluids is essential for crime scene reconstruction and for improving the reliability of expert testimonies. Messenger RNA (mRNA) analysis by reverse transcription quantitative PCR (RT-qPCR) has been used in forensic genetics, particularly for body fluid identification. It is a relative quantification method that compares the Ct values of target and reference gene. Thus, the method is unsuitable for determining exact copy numbers of the target gene. To address this limitation, this study performed body fluid-specific mRNA analysis using two-step reverse transcription droplet digital PCR (RT-ddPCR), which is capable of absolute quantification. We found that RT-ddPCR was accurate and sensitive enough to detect as little as 1.5 copies/μl of complementary DNA (cDNA), making it suitable for application using casework samples. It was also highly specific for body fluids, as non-specific amplification did not occur. In addition, saliva-semen mixtures with ratios ranging from 1:50 to 50:1 were successfully identified. When comparing the results of RT-qPCR and RT-ddPCR, some samples were difficult to interpret because of the high Ct values of RT-qPCR. However, when the same samples were analyzed using RT-ddPCR, saliva and semen were distinctly identified. Thus, RT-ddPCR is useful for mixed samples (e.g., in sexual assault cases) with low amounts of DNA, which often leads to ambiguous results when using RT-qPCR. Other body fluids (e.g., vaginal fluid and menstrual blood) can also be identified by including additional markers. This study demonstrates the potential of RT-ddPCR for applications in forensic science.

Exploring the protein signature of endometrial cancer: A comprehensive review through diverse samples and mass spectrometry-based proteomics

Endometrial cancer (EC) is increasing incidence among women, and it constitutes a health problem for women globally. An important aspect of EC management involves the use of protein biomarkers for early detection and monitoring. Protein biomarkers allow the identification of high-risk patients, the detection of the disease in its early stages, and the assessment of treatment responses. Mass spectrometry (MS)-based proteomics offers robust analytical techniques and a comprehensive understanding of proteins. Proteomics methods allow scientists to investigate both the quantities and functions of proteins. Thus, it provides valuable insights into how proteins are altered under different conditions. This review summarizes recent advances in MS-based proteomic biomarker discovery for EC, focusing on different sample types and MS-based techniques used in clinical studies. The review emphasized in detail the most commonly used key sources such as blood, urine, vaginal fluids and tissue. Furthermore, MS-based proteomics techniques such as untargeted, targeted, sequential window acquisition of all theoretical mass spectra (SWATH-MS) and mass spectrometry imaging used in the discovery and validation/validation phases were evaluated. This review highlights the importance of biomarker discovery and clinical translation to improve diagnostic and therapeutic outcomes in EC. It aims to provide a comprehensive overview of MS-based proteomics in EC, guiding future research and clinical applications.

Identifying changes in vaginal fluid using SERS: Advancing diagnosis of vulvovaginal candidiasis

Vaginal infections, medically termed vaginitis, encompass a spectrum of symptomatic presentations arising from disturbances within the vaginal microflora. The conventional diagnostic approach relies on microscopic examination of wet preparation of vaginal discharge, considered the ‘gold standard’ in clinical practice. Complementary to this, culture-based methodologies are often employed to reinforce diagnostic accuracy. However, challenges such as subjectivity in result interpretation, resource-intensive requirements regarding skilled personnel, and reagent utilization underscore the need for alternative diagnostic strategies.In this article, we demonstrate surface-enhanced Raman spectroscopy (SERS) and partial least squares regression (PLSR) techniques to elucidate the molecular signatures present in vaginal fluids, accounting for various influencing factors, including disruptions in the natural microflora, vaginal irrigation practices, and contraceptive usage. Furthermore, we investigated the spectral manifestations associated with vulvovaginal candidiasis (VVC) relative to control samples. Each clinical specimen underwent meticulous characterization encompassing microbial composition, pH levels, purity, and other pertinent parameters.Our findings unveil significant associations between extraneous inflammatory factors such as vaginal irrigation and diminished sample purity with alterations in SERS signals. Conversely, the day of the menstrual cycle phase exhibits negligible influence on spectral profiles. Notably, VVC samples demonstrated diverse spectral responses correlating with the abundance of pathogenic bacteria. These explorations hold promise in paving the path towards developing a novel intrinsic framework for the diagnosis of vaginitis.

A Diagnostic Study Using STARD Platform on Liquid-Based Cytology in Cervical Smear and Its Positivity Rate among Females with Abnormal Vaginal Conditions Attending a Tertiary Care Center

Abstract Background: Liquid-based cytology (LBC) is a newer method of preparing cervical cell samples. This technique involves collecting cells in a liquid fixative and preparing and evaluating them. Aim: This study aims to investigate cervical smears prepared using the Ezi-Prep LBC method and analyze the positivity rate for cervical cancer and assess the diagnostic accuracy of LBC in detecting cervical abnormalities among females with abnormal vaginal conditions attending a tertiary care center. Materials and Methods: The present diagnostic study was performed in a tertiary care hospital over a period of 1 year (April 1, 2021–November 30, 2021). A total of 230 women, aged 21–70 years, presented at the gynecology outpatient department for either routine cervical screening or with complaints of vaginal bleeding, discharge, or pelvic pain. Cervical smears were prepared using the Ezi-Prep method and stained with ULTRA-PAP stain. Results: LBC smears are monolayer smears and are without nuclear overlapping with spread over a diameter of 16 mm. Minimum cellular overlapping and crowding were observed in LBC smears. The mean age of the participants was 35.5 ± 5.1 years. The smears were studied by using nine morphological parameters. Conclusion: The majority of the smears were inflammatory smears. A total of 16 cases and three cases were found to be bacterial vaginosis and candidiasis, respectively. In an 8-month study, HSIL was found in two cases, whereas LSIL was found in only one case. The positivity rate was observed to be 0.9% in HSIL cases and 0.4% in LSIL cases, 0.9% ASC-US case, and 0.4% invasive carcinoma case.

Cross-Sectional Study on the Correlation Between Vaginal Microecology and High-Risk Human Papillomavirus Infection: Establishment of a Clinical Prediction Model.

High-risk human papillomavirus (HR-HPV) is a significant risk factor for cervical precancerous lesions and cancer. This study aimed to investigate the relationship between vaginal microecology and HR-HPV infection and to evaluate the clinical applicability of vaginal microecology in predicting HR-HPV infection. Overall, 2000 women with simultaneously detected vaginal discharge and cervical HPV were selected between March 2022 and March 2023, including 241 and 1759 cases in the HR-HPV positive and HPV negative groups, respectively. No significant differences were found in age, vulvovaginal candidiasis, trichomonas vaginitis, and β-N-acetylglucosaminosidase between the two groups (P>0.05). Significant differences were observed in Lactobacillus deficiency, bacterial vaginitis (BV), aerobic vaginitis (AV), glucuronidase (GUS), sialidase (SNA), and leukocyte esterase (LE) between the two groups (P<0.05). In the multivariate logistic regression equation, Lactobacillus deficiency, BV, AV, SNA, LE, and GUS were risk factors for HR-HPV infection (P<0.05). Three prediction models, namely, logistic regression, decision tree, and random forest, were established to rank the importance of the predictors. BV ranked first among the three prediction models. The logistic regression model demonstrated the highest accuracy in predicting the risk of HR-HPV infection. The calibration curve of the logistic regression model showed a strong correlation between the predicted and actual probabilities, and decision curve analysis revealed that the prediction model had good clinical applicability. Overall, vaginal microecology imbalance was closely associated with cervical HR-HPV infection, particularly BV and AV. The logistic regression model for the risk of HR-HPV infection based on six predictive factors (BV, AV, LE, SNA, Lactobacillus deficiency, and GUS) had good accuracy and clinical applicability.

Influence of free and microencapsulated recombinant rabbit nerve growth factor with chitosan on rabbit sperm quality parameters.

β-nerve growth factor (βNGF) plays a crucial role in reproductive physiology and sperm quality. Enzymatic activity of seminal plasma and vaginal fluids reduces available βNGF and it has been demonstrated that chitosan microspheres could protect rrβNGF from degradation. This study examined the effects of microencapsulated rrbNGF with chitosan on rabbit sperm viability, motility and capacitation status. Results showed that 0.5 and 1 μg/mL of microencapsulated rrβNGF, as well as free rrβNGF or empty microspheres, did not adversely affect sperm viability or total motility after 2 h of incubation. However, the highest progressivity kinetic parameters were observed with 1 μg/mL free rrβNGF, while the highest curvilinear velocity (VCL) occurred with 0.5 μg/mL microencapsulated rrβNGF. Empty chitosan microspheres did not induce acrosome reaction (AR), but both concentrations of free and rrβNGFch favoured AR during invitro incubation. The study suggests that using chitosan spheres did not show any adverse effects on sperm traits, unlike free rβNGF and rrβNGFch promoted capacitation and AR. Further research is needed to explore the potential of rrβNGFch in modifying invitro capacitation and inducing ovulation during artificial insemination.

Evaluation of the Causative Microorganisms and Antibiogram Results in Women with Vaginal Swab Culture Taken with Prediagnosis of Vaginitis

Aim: Vaginitis occurs when the vaginal flora is disturbed. This study aimed to evaluate the demographic data, causative microorganisms, and antibiogram results of women who underwent vaginal swab culture with a prediagnosis of vaginitis. Methods: Vaginal swab samples from 314 women who visited the Kafkas University Department of Obstetrics and Gynecology were included in the study. Women with immunosuppressive diseases, gynecological malignancies, and IUD use were excluded. Vaginal discharge or swab samples were Gram stained and cultured on various media. Microorganisms were identified using conventional and biochemical methods, and antibiotic susceptibility tests were performed using the Kirby-Bauer disk diffusion method, according to the EUCAST guidelines. Statistical analyses were performed using SPSS, with categorical variables assessed using the chi-square test or Fisher's exact test, and continuous variables assessed using the Mann-Whitney U test. The study complied with the recommendations of the Declaration of Helsinki for human biomedical research and was approved by the Non-Interventional Clinical Research Ethics Committee of the Kafkas University Faculty of Medicine. Results: The median age of 314 women included in this study was 39 (20-69) years. . In total, 73.6% (n=231) were premenopausal, 24.5% (n=77) were postmenopausal, and 1.9% (n=6) were pregnant. The most common complaint was abdominal/pelvic pain (142, 45.2%). Vaginal cultures from 123 women (39.1%) showed the growth of different microorganisms. The most common causative microorganism was Escherichia coli (41.5%). According to the antibiogram results, the most sensitive antibiotic was gentamicin (65.9%), and ampicillin (52.8 %) was the most resistant. Conclusion: It is important to quickly and accurately identify microorganisms involved in the etiology of the correct treatment.

Interleukin-17 Gene Polymorphisms and Hepatitis B Virus Infection in a Sample of Iraqi Patients

Hepatitis B, a chronic inflammatory liver condition, constitutes a significant global health issue, with 3 million new cases and over 1 million deaths annually (when combined with hepatitis C). The infection may be acute or chronic, and it transmits horizontally by contact with biological fluids such saliva, blood, semen, tears, vaginal secretions, or perinatal fluids following childbirth, which are transferred from mother to infant. Infections can be easily prevented with immunization, typically administered shortly after birth; nevertheless, if neglected, chronic hepatitis B may lead to severe outcomes, including liver cancer or cirrhosis. Interleukin-17A, a pro-inflammatory cytokine, is essential in the immune response to many infections and is implicated in autoimmune diseases. The cytokine interleukin-17 (IL-17A) is only secreted by activated T cells. cDNA of IL-17 has been isolated and cloned from murine hybridomas (cytotoxic T lymphocyte antigen 8 (CTLA-8)). Cytokine imbalance is a crucial factor in the progression and growth of the hepatitis B virus (HBV). A cross-sectional study was conducted including 180 patients with HBV infection at the Digestive and Liver Diseases Teaching Hospital in Baghdad province, from December 14, 2022, to February 15, 2023. This study comprised two groups: the first group consisted of 40 HBV antibody-positive patients, while the second group included 40 HBV antibody-negative patients, along with a control group of 20 individuals. A blood sample of 5 ml was collected from each patient, divided into 2 ml in an anticoagulated EDTA tube and 3 ml in a gel tube. Whole blood with anticoagulated samples was utilized under optimal conditions for DNA extraction, while serum was isolated from blood for biochemical tests. The study comprised 180 patients, categorized into three groups: HBV Positive, HBV Cleared, and Control. The HBV Positive cohort consists of 99 individuals, comprising 54 males (54.45%) and 45 females (45.45%). The average age in this cohort is 42.52 years, accompanied by a standard deviation of 15.13 years. Of these individuals, 84 (84.85%) are wed. The HBV Cleared group has 45 individuals, including 24 males (53.34%) and 21 females (46.67%). The average age in this cohort is 48.43 years, with a standard deviation of 13.98 years. A predominant 39 persons (86.67%) are wed. The Control group comprises 36 individuals, primarily male, consisting of 24 men (66.67%) and 12 females (33.34%). Genotype distribution for two genetic markers, rs2275913 and rs10484879, among three groups: HBV Positive, HBV Negative, and Control. In the HBV Positive group for the rs2275913 marker, the AA genotype is present in 30 patients, the AG genotype in 36 patients, and the GG genotype in 36 patients. In the HBV Negative group, the AA genotype is observed in 9 patients, the AG genotype in 12 patients, and the GG genotype in 21 patients. Multiple research investigations have concentrated on the role of SNPs in the IL17A gene, particularly rs2275913 and rs10484879, in the susceptibility to chronic HBV infection. The polymorphisms were specifically examined for their possible impact on immune response and disease progression in patients infected with HBV. A study of the Han Chinese population demonstrated a significant correlation between the GG genotype and G allele of rs2275913 and an increased risk of HBV infection, suggesting a causal relationship with heightened susceptibility to viral infection.

FREQUENCY OF BACTERIAL VAGINOSIS AMONG WOMEN PRESENTING WITH PRETERM LABOUR

Background: Preterm delivery is of major medical, economic, and social importance worldwide. The incidence is between 5–10% in most developed countries. Both short-term and long-term issues may arise from preterm delivery. Preterm delivery is the cause of almost 85% of long-term disabilities in healthy babies and 75% of new-born deaths. This study aimed to determine the frequency of bacterial vaginosis among women presenting with preterm labour. Methods: This cross-sectional descriptive study was conducted in Department of Obstetrics &amp; Gynaecology, Women Medical College, Abbottabad, and Women &amp; Children Hospital Abbottabad from Jun to Dec 2023. A total of 174 women with preterm labour were included in the study. All women were examined as per Amsel’s clinical diagnostic based on four factors, i.e., Thin grey homogeneous vaginal discharge, fishy smell on Amine test, clue cells of &gt;20% on microscopy, and vaginal pH&gt;4.5. Results: Age limit 15–45 years with mean age of 27.471±3.77 years, mean gestational age 29.546±3.45 weeks, mean parity 1.396±1.45 and mean Gravida was 2.396±1. Bacterial vaginosis was seen in 11.5% patients. Conclusion: There is a correlation between premature labour and bacterial vaginosis. It requires attention to lower morbidity and mortality.

Local inflammatory factors in pregnant women with various methods of cervical insufficiency treatment

the reasons for the formation of cervical insufficiency are considred to be different from violation of the ratio of connective tissue elements due to its genetic characteristics to hormonal imbalance, and the predominance of pro-inflammatory factors of the immune system. A special attention is devoted to clinical situations, when cervical insufficiency was diagnosed in terms 22-24 weeks, the treatment means an alternative between emergency cerclage and obstetric pessary. The gaol of study – to compare dynamic of vaginal microbiota and local cervical immune factors by use of different cervical insufficiency treatment methods. Materials and methods. 81 pregnant with cervical insufficiency, diagnosed in term 22-24 weeks were observed, 47 pregnant treated by cerclage procedure (group A), and 34 were fitted with an obstetric pessary (group B). 30 healthy pregnant women in the period of 22 weeks formed group C. In all patients before treatment and every two weeks after it microscopy of vaginal discharges according to Hay/Ison criteria and evaluation of cervical cytokines were performed. Results. The balance by obstetric pessary use of type I and type III by Hay-Ison criteria being similar before treatment with pregnancy prolongation is changing dramatically to the prevalence of bacterial vaginosis be use of obstetric pessary – from 30,3% and 21,2% in 2 weeks to 25,0% and 41,7% in 6 weeks, by cerclage – from 43,5% and 14,9% in 2 weeks to 30,3% and 17,5% in 6 weeks. Patients with cervical insufficiency have increased concentration of IL-6 and IL-10, but by use of obstetrical pessary additionally growth of IL-8 from 42,3 pg/ml in 2 weeks to 187,6 pg/ml in 6 weeks is registered as well as decreasing of SLPI from 1,5 μg/ml to 0,6 μg/ml. Both changes show progression of inflammation and are associated with worth pregnancy outcomes. In the same time, cerclage is assocated with growth of SLPI from 1,9 μg/ml to 4,3 μμg/ml, what is a marker of adequate immune reaction by pregnancy. There is a difference between the groups of cerclage and obstetric pessary in dynamic of microbiota changes - a tendency to increasing of laboratory criteria of bacterial vaginosis frequency in group of obstetric pessary in 2 weeks becomes significant in 4 and more in 6 weeks comparing with group of cerclage. Proper to cervical insufficiency high concentration of proinflammatory IL-6 and IL-10 by use of obstetrical pessary is complicated by increasing of IL-8 and decreasing of SLPI, what means an activation of cervical inflammation, by cerclage – a increasing of SLPI is observed, what is favourable for pregnancy.

Evaluation of polymer combinations in vaginal mucoadhesive tablets for the extended release of acyclovir

Genital herpes, caused by herpes simplex virus type 2 (HSV-2), affects nearly 500 million people, mostly women. Since the main route of transmission is sexual contact, the development of an acyclovir extended-release vaginal microbicide would be a suitable tool for the prevention of virus transmission. In this work, we evaluated the potential of three polymers with different characteristics (chitosan, xanthan gum and ethyl cellulose) for obtaining acyclovir extended-release vaginal tablets. By combining the polymers, certain useful synergies were observed to modify their mucoadhesive capacity and control drug release. In the swelling studies, it observed that a polyelectrolyte complex with more moderate swelling and sustained gelation was formed between chitosan and xanthan gum exclusively in acidic medium (simulated vaginal fluid). This complex allowed prolonging the mucoadhesion of the tablets in ex vivo studies performed with vaginal mucosa, which would translate into better retention in the vagina after administration. In addition, the combination of chitosan and xanthan gum allowed obtaining a controlled release of acyclovir for 5 days, regardless of the pH of the medium, which would guarantee that drug release continues even in the presence of seminal fluid.

Chronic lower abdominal pain in an elderly female patient: a case report about sigmoid colon fistula and pelvic abdominal infection

An elderly woman patient presented with a history of recurrent right lower abdominal pain accompanied by fever and abnormal vaginal discharge for 36 years worse for two weeks. Conservative medical treatment was ineffective, by laparoscopic exploration combined with intraoperative colonoscopy, the presence of a sigmoid colon fistula and pelvic abdominal infection with foreign bodies were confirmed. It was hypothesized that the occurrence of recurrent right lower abdominal pain and intestinal fistula may be potentially associated with tubal injection sterilization performed 36 years ago.

Creation of neovagina in women with Müllerian agenesis (Mayer-Rokitansky-Kuster-Hauser syndrome) using fresh human amnion.

Several graft options can be used to construct a neovagina. This study aimed to evaluate the efficacy of creating a neovagina using a fresh human amnion in women with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. Ten patients were analyzed retrospectively. Anatomical success was defined by a postoperative vaginal length ≥5 cm, and a width sufficient to comfortably accommodate the insertion of two fingers. Functional success was achieved when a score of >26.5 was attained on the Arabic validated version of the functional sexual function index (FSFI). The mean vaginal length before surgery was 2.15±0.85 cm (range, 1.5-4.5). The mean vaginal length after surgery was 5.5±0.53 cm (range, 5-6), and all patients (n=10) achieved anatomical success. The FSFI score after surgery was 29.2±2.4, and eight patients achieved functional success. The mean operative time and estimated blood loss were 83.5±50.31 minutes (range, 42-210) and 122.0±75.69 mL (range, 20-250), respectively. None of the patients required intraoperative blood transfusion or experienced injury to vital organs. Four patients developed postoperative leukocytosis within 48 hours, and one patient experienced chronic pelvic pain that lasted more than 6 months postoperatively. No major postoperative complications, such as pelvic abscesses, open wounds, chronic vaginal discharge, or reoperation, were reported. Surgical dissection of the vesicorectal space and utilization of fresh human amnion to create a neovagina over a vaginal mold are technically feasible and safe, and are linked to favorable anatomical and functional outcomes in MRKH patients with vaginal agenesis.

Abstract C053: Racial differences in adverse sexual symptoms and implications for quality of life and adjuvant endocrine therapy adherence among women with early-stage breast cancer

Abstract Background Adjuvant endocrine therapy (AET) is effective at reducing breast cancer recurrence risk. It is associated with adverse symptoms, including sexual symptoms (e.g., vaginal dryness, reduced libido, dyspareunia), that can contribute to medication nonadherence and poor quality of life (QoL). Black women are least likely to start and maintain AET. We conducted post hoc analysis of a randomized clinical trial (RCT) to examine racial differences in how sexual symptoms affect sexual satisfaction and how these contribute to differences in AET adherence for Black and White women with early-stage breast cancer. Methods We used data from a nonblinded RCT of women diagnosed with early-stage (Stage I-III), hormone receptor-positive breast cancer and prescribed AET at a regional cancer center in the U.S. Mid-South. We restricted to Black and White participants who completed surveys at enrollment, 6-, and 12-months (N=275). The Functional Assessment of Cancer Therapy-Endocrine Subscale (FACT-ES) captured sexual symptoms (e.g., vaginal itchiness, bleeding, dryness, discharge, change in interest in sex, and pain with intercourse) and PROMIS Sexual Function and Satisfaction captured changes in sexual satisfaction with 5-item options ranging from “not at all” to “very much.” The 12-item Short Form Health Survey measured QoL with physical and mental health component summaries (higher scores indicated better QoL). AET adherence, captured by an electronically monitored pillbox, was measured as the proportion of days participants took their medication as prescribed over the 1-year follow-up. We conducted race-stratified linear regressions to examine associations of sexual symptoms with QoL and adherence. Results Among 275 participants, 102 (37%) were Black. Black women reported greater severity of vaginal discharge and that loss of sexual satisfaction was due to sexual symptoms at 6- and 12-months (p&amp;lt;0.05). Vaginal itchiness, vaginal discharge, painful intercourse, and loss of interest in sex were associated with lower mental QoL for Black and White women at all three time points. However, loss of interest in sex was associated with lower physical QoL at all three time points for Black women only. Worsening vaginal dryness was associated with lower 6-month AET adherence for Black (p=0.018) but not for White women (p=0.90). Similarly, lower sexual interest and lower sexual satisfaction was associated with lower 12-month AET adherence for Black women (p&amp;lt;0.05) but not for White (p=0.21 and p=0.13, respectively). Conclusion Women with early-stage breast cancer on AET reported adverse sexual symptoms with associated reductions in their sexual satisfaction and physical and mental QoL. Vaginal dryness, reduced libido, and lowered sexual satisfaction are associated with AET nonadherence among Black women, a group with known adherence barriers and recurrence risks. Our findings suggest that adverse sexual symptoms and sexual health challenges contribute to racial disparities in AET adherence and QoL. Oncosexuality care interventions for Black women are needed.

Saliva as a Potential Source of Biomarkers in Cows with Metritis: A Pilot Study.

Metritis affects 5-20% of cows after parturition, negatively impacting animal welfare and the profitability of dairy farms, increasing culling rates and costs, and decreasing productivity and reproduction rates. This study compared the results of a comprehensive biochemical panel consisting of 25 salivary and 31 serum analytes between healthy cows (n = 16) and cows with metritis (n = 12). Descriptive parameters such as depression, rectal temperature, body condition score (BCS), heart rate, respiratory rate, mucous color, ruminal motility, vaginal discharge, milk production, and complete hematology analyses were also assessed for comparative purposes. The biochemistry analytes comprised five analytes related to stress, five to inflammation, five to oxidative status, and nineteen to general metabolism. The two-way ANOVA analysis revealed that, in saliva, eight biomarkers (lipase, adenosine deaminase (ADA), haptoglobin (Hp), total proteins, g-glutamyl transferase (gGT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and creatine kinase (CK)) were significant higher in cows with metritis. In serum, eight biomarkers (ADA, Hp, serum amyloid A (SAA), fibrinogen, ferritin, AOPPs/albumin ratio, non-esterified fatty acids (NEFAs), and bilirubin) were significantly higher in cows with metritis, whereas six (total esterase (TEA), albumin, urea, lactate, phosphorus, and calcium) were lower. Of the total number of 23 biomarkers that were measured in both saliva and serum, significant positive correlations between the two biofluids were found for six of them (Hp, FRAP, CUPRAC, AOPPs, urea, and phosphorus). Urea showed an R = 0.7, and the correlations of the other analytes were weak (R < 0.4). In conclusion, cows with metritis exhibited differences in biomarkers of stress, inflammation, cellular immune system, and general metabolism in both salivary and serum biochemistry profiles. These changes were of different magnitudes in the two biofluids. In addition, with the exception of ADA and Hp, the analytes that showed changes in the saliva and serum profiles of cows affected by metritis were different. Overall, this report opens a new window for the use of saliva as potential source of biomarkers in cows with metritis.

Optimizing Human Papillomavirus (HPV) Screening: Urine Sample Analysis and Associated Factors in Uzbekistan.

Objective This study assessed the accuracy of detecting Human Papillomavirus (HPV) DNA in urine samples compared to cervical samples and identified factors associated with HPV DNA positivity in Uzbekistan. Methods A total of 218 paired urine and cervical samples were collected from women in Uzbekistan. HPV DNA was detected using polymerase chain reaction (PCR) with genotyping. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and Cohen's Kappa coefficient were calculated. Univariate and multivariate analyses were conducted to identify factors associated with HPV DNA positivity. Results The study included 32.6% (71/218) positive HPV DNA by cervical samples, which demonstrated 19.7% (43/218) HPV DNA presence by urine samples. Urine HPV testing had a sensitivity of 57.7%, specificity of 98.6%, PPV of 95.3%, NPV of 82.9%, and Kappa coefficient of 60.1. To reveal factors associated with HPV DNA positivity, we set the positive 71 cases as the main group, and 147 negative samples as the control group. The results of the multivariate analysis found the association between HPV DNA positivity and included age 31-40 years (AOR=8.2), working as medical staff (AOR=7.51), condom use (AOR=0.12), having foamy (AOR=7.26) or purulent (AOR=6.84) vaginal discharge. Conclusion Urine HPV testing showed good agreement with cervical samples, although sensitivity was lower than some previous reports. Several sociodemographic and clinical factors were associated with HPV DNA positivity. Further optimization of urine collection, storage, and testing methods may improve sensitivity. Targeted screening of high-risk groups could enhance HPV prevention strategies in Uzbekistan.

Vertical transfer of gut microbiota from dam to neonate calf in the early of life

The aim of this study was to investigate the vertical transfer of microbiota from dams to the offspring. We studied a pair of 20 dams and its offspring. Maternal sources (colostrum, feces and vaginal secretion) and newborn fecal samples were analyzed using 16S rDNA amplicon sequencing on days 1, 3, 7, 14 and 28. Overall, newborns were maintained healthy and did not receive antimicrobial therapy. The Source Tracker analysis indicated that the newborn fecal microbiota was similar to colostrum and vaginal secretion from day 1 up to 7. However, an unknown source (probably from the environment) showed a gradual increase in its similarity with fecal samples from calves measured from day 3 to 28. The most abundant bacteria groups on meconium (day 1) and calf fecal samples on day 3 were Escherichia-Shigella and Clostridium, respectively. On day 7, the predominant genus were Bifidobacterium and Lactobacillus, while Fusobacterium was the most abundant genus on day 14, coinciding with the diarrhea peak. Faecalibacterium showed a gradual increase throughout the neonatal period. Maternal sources contribute to the neonatal microbiota, however other unknown sources (probably environment) had a strong influence on development of the gut microbiota later in the neonate period.
