Project description:Introduction and Hypothesis: Identify processes contributing to pelvic organ prolapse (POP) by transcriptional profiling of pelvic connective tissue in conjunction with light microscopy. Methods: We performed a frequency matched case-control study of women undergoing hysterectomy. Total RNA, extracted from uterosacral and round ligament samples used to generate labeled cRNA, was hybridized to microarrays and analyzed for the expression of 32,878 genes. Significance Analysis of Microarrays, (Stanford University, CA), identified differentially expressed genes used for ontoanalysis, and quantitative PCR (qPCR) confirmed results. Light microscopy confirmed tissue type and assessed inflammatory infiltration. Results: The analysis of thirty-four arrays revealed 249 differentially expressed genes with fold changes larger than 1.5 fold and false discovery rates M-bM-^IM-$5.2%. Immunity and Defense was the most significant biological process differentially expressed in POP. Selected qPCR confirmed 4 genes. Light microscopy showed no inflammatory infiltrates. Conclusions: Genes enriched for Immunity and Defense contribute to POP independent of inflammatory infiltrates. Keywords: whole tissue (endopelvic fascia) type comparison This was a group matched case control study of 8 women with pelvic organ prolapse versus 9 non-prolapse controls, both undergoing hysterectomy for benign conditions. Two separate pelvic support tissues were collected from each patient. The uterosacral ligament and round ligament tissue was removed at the time of hysterectomy, RNA was extracted and ABI whole genome chips used to identify differences in expression profiles of individual samples. Various ethnic groups, age groups and menopausal status were included.

Project description:Pelvic organ prolapse (POP) affects a large proportion of adult women. With the increase in global population ageing, the prevalence of POP is expected to increase in upcoming decades, which will impose a substantial medical burden. Therefore, suitable therapeutical target is important. However, due to the pathogenesis of POP is still unclear, it leads to the failure of POP repair. Herein, we identified changes in ncRNA, and mRNAs in the anterior vaginal wall and uterosacral ligament in patients with POP, providing new insights into the pathogenesis of POP and new targets for treatment.

Project description:Objective: To evaluate whether the combined measurement of pelvic organ mobility and levator hiatus area improves the sensitivity of transperineal ultrasound (the index test) for diagnosing pelvic organ prolapse (POP). Methods: We retrospectively recruited women who had been examined in a tertiary gynecological center for symptoms of lower urinary tract incontinence and/or POP between January 2017 and June 2018. We excluded patients who had undergone hysterectomy previously or those who had received corrective surgery. All subjects underwent a standardized interview, POP quantification (POP-Q) examination (a reference standard for patients and controls), and ultrasound measurements of the levator hiatus area at rest (rHA), on contraction (cHA), and on Valsalva (vHA). We also determined the mobility of the bladder neck (BNM), cervix (CM), and rectum ampulla (RAM). Receiver operating characteristic (ROC) curve analyses were performed to determine cut-off values for diagnosis. Diagnostic performance was assessed by sensitivity, specificity, and area under curve (AUC). Results: A total of 343 women were eligible for analysis, including 247 POP patients (stage 2-3 by POP-Q) and 96 controls. Compared with controls, POP cases had significantly higher values for rHA, vHA, cHA, BNM, CM, and RAM. Each parameter was identified as a significant discriminator for POP and controls, as determined by ROC curve analysis, although the cut-off value varied slightly between different parameters. The combination of rHA, vHA, and cHA (with any HA that was ≥ the cut-off) improved the sensitivity from 64-89 to 89-93%. The combination of pelvic organ mobility with rHA, vHA, and cHA, further increased the sensitivity from 89-93 to 95-97%. Conclusion: The combination of levator hiatus area and pelvic organ mobility improved the sensitivity of transperineal ultrasound in the diagnosis of POP, whether used as a frontline test to assist POP-Q grading or to monitor the effect of pelvic floor exercise programs.

Project description:BackgroundUp to 50% of women will develop pelvic organ prolapse (POP) over their lifetime. Symptoms include pain, bulge, urinary, bowel and sexual symptoms affecting all aspects of a woman's life. This study explores the lived experience of women with POP.MethodologyA qualitative study was undertaken. Following institutional ethical approval women from an online peer support group (n = 930 members) were recruited to participate in semi-structured interviews. Inclusion criteria stipulated women (> 18years), pre-menopausal, at least one-year post-partum, diagnosed with POP and aware of their diagnosis. Semi-structured interviews were undertaken with a clinician specialising in pelvic health. A battery of questions was designed to elicit discussion on their experience of being diagnosed with POP and its impact on daily life and relationships. Interviews were carried out via Zoom, recorded and transcribed. Thematic analysis was undertaken.FindingsFourteen women (32-41 years), para 1-3 participated. All had at least one vaginal birth; three had vacuum, four had forceps operative births. All had Grade 1-3 POP. Interviews lasted 40-100 minutes. Three core themes with subthemes were identified; biological/physical, psychological and social. Women were particularly affected in terms of sport and exercise participation, their own perceptions of their ability as mothers and fear of their condition worsening. They described societal attitudes, reporting stigma around POP and women's pelvic health in general, expectations placed on women to put up with their symptoms and an idealised perception of new motherhood.ConclusionsThe impact of POP from a biopsychosocial perspective reflects other chronic conditions. Prevention, early education and supports for developing strong self-management approaches would be beneficial for long term management of this condition.

Project description:This study aimed to explore the effect of pelvic reconstruction surgery on the relation of pelvic organ prolapse (POP) and overactive bladder (OAB) and the impact of preoperative vaginal oestrogen supplement on vaginal tissue. A total of 100 postmenopausal women with symptomatic POP who underwent pelvic reconstruction surgery (laparoscopic sacrocolpopexy or transvaginal mesh) were enrolled in this study. Preoperative vaginal oestrogen was prescribed in 28 cases. The evaluation tools consisted of POP-Q, urodynamic study, Overactive Bladder Symptom Score (OABSS), and urinary NGF. Vaginal maturation index and vaginal specimens for hormone receptors study were investigated during operation to evaluate the effect of topical oestrogen. Follow-up assessments were performed at 1, 3, and 6 months after surgery. Preoperatively, 58 (58%) were POP with OAB. After reconstruction surgery, the OABSS decreased significantly (6.87 ± 0.85 vs 3.77 ± 0.61, p < 0.001) at postoperative 6 months in the group. Remarkable increasing trends of urinary NGF levels are noted till 3 months postoperatively, then decreasing to the baseline level at 6 months postoperative follow-up. Remarkable decrease of mRNA of the androgen receptor and significant higher expression of progesterone receptor (PR) were noted after use of the vaginal oestrogen cream. The severity of OAB in the POP women shows moderate degree according to OABSS. Pelvic reconstruction surgery can significantly improve the OAB symptoms. The surgery induced inflammation effect lasts for about 6 months. Short-term preoperative supplement of topical oestrogen brings alterations of the vaginal epithelium.

Project description:IntroductionSow mortality in the U.S. swine industry has increased in recent years, for which pelvic organ prolapse (POP) is a major contributor, accounting for 21% of all sow mortality. Dysbiosis of microbial communities has been associated with disease and reproductive dysfunction in several species, and previous studies have shown changes in vaginal microbiota in sows with increased risk for POP during late gestation. However, there is insufficient knowledge surrounding the potential relationship between fecal microbiota and POP in sows. Therefore, the study objective was to identify differences in sow fecal microbiota and determine if fecal and vaginal microbial communities are correlated in relation to POP risk.MethodsSows were evaluated for POP risk using an established perineal scoring system, with a perineal score (PS) of 1 (PS1) presuming little to no risk of POP to a PS of 3 (PS3) presuming high risk of POP. In the current study, 2,864 sows were scored during gestation week 15, and 1.0%, 2.7%, and 23.4% of PS1, PS2, and PS3 sows, respectively, subsequently experienced POP. Fecal swabs (n = 215) were collected between gestation days 108-115, DNA was extracted, and 16S rRNA gene amplicon sequencing libraries were analyzed using mothur, phyloseq and SAS in reference to PS and POP outcome. Additionally, co-occurrence networks were constructed using CoNet to compare fecal and vaginal microbiota from the same cohort of sows and identify correlations between different taxa.ResultsDifferences in fecal community composition (PERMANOVA; P < 0.05), structure (alpha diversity measurements; P < 0.05), and 13 individual operational taxonomic units (OTUs) were revealed between PS1 and PS3 assigned sows. No differences in fecal microbiota were detected as a result of POP outcome. However, the abundances of several taxa were correlated across sample collection sites, suggesting the fecal and vaginal microbial communities may be related to one another.DiscussionCollectively, fewer differences in the fecal microbiota exist in sows with differing risk for POP compared to the vaginal microbiota, suggesting the vaginal microbiome may be more relevant in relation to POP outcome, although correlations between fecal and vaginal communities may provide insight for strategies to combat POP.
