Abstract
OBJECTIVE Senolytic agents have the potential to target age-related pathology associated with cellular senescence and reduce senescent cell activity in several disease processes. We utilized a mouse model of pelvic organ prolapse, Fibulin-5 knockout (Fbln-5-/-) mice, to assess the ability of dasatinib and quercetin (D+Q) to prevent development of prolapse. METHODS Four-week-old female Fbln-5-/- (n=63) and wild-type (WT) mice (n=54) were assigned to control (vehicle injection) or treatment (D = 5 mg/kg, Q = 50 mg/kg) groups. Weekly oral gavage injections were administered from weeks 4-8 of life. Pelvic organ prolapse quantification system measurements were obtained weekly. Vaginal tissue was harvested at 10, 12 and 20 weeks. Tissue analysis included immunostaining for cell cycle inhibitors, multiplex cytokine analysis, senescence-associated-β-galactosidase (SA-β-Gal) and histologic analysis of extracellular matrix proteins. RESULTS Perineal body length was significantly longer in Fbln-5-/- treatment mice at 20 weeks. Expression of p16 and p53 was decreased in Fbln-5-/- treatment mice compared to controls (4.0% vs. 26.7%, p=0.0124 and 2.9% vs. 16.8%, p=0.272) at 20 weeks. Expression of SA-β-Gal and senescence-associated cytokines did not vary significantly between groups. At 20 weeks, vaginal tissue elastin content in Fbln-5-/- treatment mice increased compared to controls (1.04% vs. 0.84%, p=0.999). CONCLUSIONS D+Q injections did not result in clinically significant differences in prolapse development but did demonstrate decreased expression of cellular senescence markers in Fbln-5-/- mice. This suggests senolytic agents may mitigate contributions of cellular senescence to tissue dysfunction associated with prolapse. Further studies are needed to confirm ideal timing, dosage, and route of senolytics in prevention of prolapse.

Abstract
Pelvic floor dysfunction (PFD) is common to be associated with pregnancy and birth. To date, no research has been done to understand whether the perineal massage and warm compresses technique has an impact on pelvic floor dysfunction. To assess the impact of perineal massage and warm compresses technique during the second stage of labor in pelvic floor dysfunction at 3 and 6 months postpartum. Of the 800 women recruited to randomised controlled trial to prevent perineal trauma, 496 were included in the study, with 242 (48.8%) assigned to the Perineal Massage and Warm Compresses (PeMWaC) group and 254 (51.2%) to the control group (hands-on). Used the Pelvic Floor Distress Inventory-20 (PFDI-20). The questionnaire is divided into three subscales: Urinary (UDI), Colorectal-Anal (CRADI), and Pelvic Organ Prolapse Distress Inventory (POPDI). The PeMWaC group had a significantly higher frequency of intact perineum (p < 0.001) and low-severity vaginal tears (tears without any other degree of perineal trauma) (p = 0.031) compared to the control group, while the control group had significantly more patients who suffered high-severity vaginal/perineal trauma (second degree perineal tears) (p = 0.031) and patients without spontaneous perineal trauma or vaginal tears who underwent episiotomy (p < 0.001). In addition, at 3 months postpartum, women in the control group had a higher Urinary Distress Inventory (UDI) score and global score, compared to the PeMWaC group, and after controlling for confounding variables, the perineal massage and warm compresses technique was associated with lower UDI scores at 3 months postpartum compared to control group. At 6 months postpartum, there were no differences in the UDI or global scores, indicating general recovery from perineal trauma. In addition to reducing perineal trauma during birth, the perineal massage and warm compresses technique was associated with a lower prevalence of early PFD symptoms, mainly urinary distress, at 3 months.Trial registration http://www.ClinicalTrials.gov NCT05854888, retrospectively registered.

Pessaries for pelvic organ prolapse: evaluation of vaginal discharge and pain during pessary cleaning in an outpatient setting. Int Urogynecol J 2024; 35:333-339. [PMID: 37796331 DOI: 10.1007/s00192-023-05648-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 08/29/2023] [Indexed: 10/06/2023]
Abstract
INTRODUCTION AND HYPOTHESIS Pessary treatment for pelvic organ prolapse (POP) is effective and safe, but long-term continuation is low. Pain and vaginal discharge may play a role. This study was aimed at evaluating vaginal discharge and pain during pessary cleaning in an outpatient setting and in continuous pessary use. METHODS Women with POP who attended the outpatient clinic for pessary cleaning between January and October 2021 were included. Primary outcome was pain during removal and reinsertion of the pessary, measured by an 11-point numeric rating scale (NRS). Secondary outcome was vaginal discharge, measured by the NRS and Patient Global Impression of Change scale (PGI-C). Multiple linear regression analysis was used to identify associated variables for pain and discharge. RESULTS A total of 150 women were included. Mean NRS during pessary removal was 4.3 (± 2.7), with 25% of women scoring a 7 or higher. Mean NRS during reinsertion was 1.8 (± 2.0). A smaller genital hiatus and presence of vaginal atrophy or vulvar skin disease were associated with pain during pessary removal. Mean NRS for vaginal discharge was 2.5 (± 2.3). Twenty-five percent of women reported that their vaginal discharge was "(very) much worse" than before they used a pessary. Presence of vaginal erosions was associated with vaginal discharge in this study population. CONCLUSIONS Removing a pessary in an outpatient setting is a painful procedure for many women who use a pessary continuously. Moreover, 25% of these women experience an increase in vaginal discharge while using a pessary. Future research should focus on reducing these disadvantages.

Bearing the burden of spill-over effects: Living with a woman affected by symptomatic pelvic organ prolapse after vaginal birth - from a partner's perspective. SEXUAL & REPRODUCTIVE HEALTHCARE 2023; 37:100894. [PMID: 37586304 DOI: 10.1016/j.srhc.2023.100894] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 07/17/2023] [Accepted: 07/24/2023] [Indexed: 08/18/2023]
Abstract
INTRODUCTION Symptomatic pelvic organ prolapse (sPOP) can have a negative impact on a woman's health. While research exists about the impact of sPOP on women, little is known about the effect on their partners. Therefore, this study aimed to explore, from the partner's perspective, what it means to live with a woman with symptomatic pelvic organ prolapse after vaginal birth. METHODS A qualitative explorative design with a constructed grounded theory approach was taken to analyse the interviews of 13 partners who experienced living with a woman who had sPOP after vaginal birth. RESULTS "The theory of bearing the burden of spill-over effects" was constructed based on a core category: "Facing a new restricted life", with related categories "Giving up valued activities"; "Struggling with added demands"; "Changing intimate behaviour" and "Redefining future family planning". The theory also contains factors constraining and enabling adjustment to the new reality. While the shortcomings of healthcare constrained the process of adjustment, getting competent treatment and the feeling of love for the family enabled it. CONCLUSION This study demonstrated that women's sPOP had an apparently negative impact on partners' health behaviours, sexual health, relationship harmony, and psychological well-being. The partners indicated they were unprepared for post-birth adversities and distressed by the lack of treatment options. There is a need to develop prenatal information highlighting the potential risks of sPOP which may be accompanied by levator ani muscle injury, implement guidelines for the prevention and management of these conditions, and offer targeted support to partners if needed.

Abstract
BACKGROUND Pelvic floor disorders are common, especially in pregnancy and after delivery, in the postmenopausal period, and old age, and they can significantly impact on the patient's quality of life. METHODS This narrative review is based on publications retrieved by a selective search of the literature, with special consideration to original articles and AWMF guidelines. RESULTS Pelvic floor physiotherapy (evidence level [EL] 1), the use of pessaries (EL2), and local estrogen therapy can help alleviate stress/urge urinary incontinence and other symptoms of urogenital prolapse. Physiotherapy can reduce urinary incontinence by 62% during pregnancy and by 29% 3-6 months post partum. Anticholinergic and β-sympathomimetic drugs are indicated for the treatment of an overactive bladder with or without urinary urge incontinence (EL1). For patients with stress urinary incontinence, selective serotonin-noradrenaline reuptake inhibitors can be prescribed (EL1). The tension-free tape is the current standard of surgical treatment (EL1); in an observational follow-up study, 87.2% of patients were satisfied with the outcome 17 years after surgery. Fascial reconstruction techniques are indicated for the treatment of primary pelvic organ prolapse, and mesh-based surgical procedures for recurrences and severe prolapse (EL1). CONCLUSION Urogynecological symptoms should be specifically asked about by physicians of all relevant specialties; if present, they should be treated conservatively at first. Structured surgical techniques with and without mesh are available for the treatment of urinary incontinence and pelvic organ prolapse. Preventive measures against pelvic floor dysfunction should be offered during pregnancy and post partum.

Abstract
OBJECTIVE The objective of this study was to develop an in vitro model of cellular senescence using rat vaginal fibroblasts and determine the effects of treatment with senolytics. METHODS Rat vaginal tissue biopsies were collected. Primary vaginal fibroblasts were isolated and characterized by immunofluorescence. To induce cellular senescence, fibroblasts were treated with etoposide at 3, 10, and 20 mM for 24 hours, followed by treatment with the senolytics dasatinib (1 mM) and/or quercetin (20 mM). After treatment, RNA was extracted and the expression of selected genes was quantified. Immunostaining of senescence markers was also performed. RESULTS Fibroblasts were confirmed by positive immunostaining for α-smooth muscle actin and vimentin, and negative immunostaining for pan-cytokeratin. Treatment with etoposide resulted in a dose-dependent increase in expression of the senescence-associated secretory phenotype markers MMP-7, MMP-9, and IL-b1 (P < 0.05) compared with controls. Immunostaining showed increased expression of γ-H2A and p21 after treatment with etoposide. Cells treated with dasatinib and quercetin after etoposide treatment had decreased expression of p21, MMP-7, MMP-9, and IL-1b compared with cells treated only with etoposide (P < 0.05). CONCLUSIONS Upregulation of senescence-associated factors provided evidence that senescence can be induced in vaginal fibroblasts in vitro. Furthermore, treatment with the senolytics dasatinib and quercetin abrogated the senescence phenotype induced by etoposide in rat vaginal fibroblasts. Our findings provide a novel model for the study and development of new therapies targeting the disordered extracellular matrix associated with pelvic organ prolapse.

Abstract
INTRODUCTION AND HYPOTHESIS Age is named as a risk factor for pelvic organ prolapse (POP), despite not being the primary outcome for many observational studies. Postmenopausal status is another associated factor but has many confounders. We aimed to systematically review the role of age and/or postmenopausal status in POP development. METHODS Systematic review addressing age and hormones, more specifically by postmenopausal status, from inception to March 2020 in four databases (PubMed, Embase, WOS, Cochrane Library). Quality of evidence was classified by the ROBINS-I classification for non-randomized studies. Experimental studies, animal studies, studies linking age with recurrent POP and case series were excluded. Effect estimates were collected from adjusted odds ratio plus 95% confidence intervals. Significance level was 5%. A discussion exploring mechanistic factors was also included. RESULTS Nineteen studies (11 cross sectional, 6 cohort and 2 case control) were included for quantitative analysis. Only two studies presented a low overall risk of bias for age; most of the domains were of moderate risk. Every additional year was responsible for a 10% increase in the risk to develop POP (OR = 1.102 [1.021-1.190]; i2 = 80%, random analysis, p = 0.012). This trend was confirmed when age was dichotomized into a cutoff of 35 (p = 0.035) and 50 (p < 0.001) years. Although an increase in the risk for POP was noted in postmenopausal women, this did not reach statistical significance (OR = 2.080 [0.927-4.668], i2 = 0%, p = 0.076). CONCLUSION Age is a risk factor for POP; postmenopausal status was not statistically associated with POP, prompting the need for further studies addressing this factor.

Abstract
INTRODUCTION AND HYPOTHESIS We aimed to develop and validate a new MRI-based perineal membrane reconstruction and morphological measurement technique, and test its feasibility on nulliparous and parous women to determine the effects of pregnancy and childbirth on the perineal membrane. METHODS The perineal membrane was traced on high-resolution MRI using 3D Slicer® and analyses performed using Rhinoceros 6.0 SR23®. Validation was done by comparing MRI-based perineal membrane reconstruction to dissection measurements in a cadaver. Feasibility of reconstruction was assessed in the following three groups: nulliparous (NP), primiparous women who underwent cesarean delivery (CD), and primiparous women with vaginal delivery (VD). The following parameters were measured: (1) swinging door angle, (2) bony and (3) soft tissue attachment lengths, (4) separation at perineal body level, (5) surface area, and (6) hiatal area. ANOVA and post-hoc comparisons were performed, and the effect sizes (d) were reported. RESULTS Model reconstruction was similar to cadaver dissection findings. Morphological measurements were feasible in all women (NP, n = 10; CS, n = 6; VD, n = 19). Swinging door angle was 13o greater in CD (p = 0.03; d = 1.15) and 16o greater in VD (p < 0.001; d = 1.41) compared to NP. VD showed 13% larger separation at the perineal body than NP (p = 0.097, d = 0.84) and 23% larger hiatal area than CD (p = 0.14, d = 0.94). CONCLUSION This novel and anatomically validated MRI-based perineal membrane reconstruction technique is feasible. Preliminary findings show that pregnancy and childbirth both influence perineal membrane morphology with VD being associated with the largest swinging door angle and perineal body separation.

Abstract
OBJECTIVE This study aimed to determine whether measures of muscular fitness modify the effect of intra-abdominal pressure (IAP) during lifting on pelvic floor support. METHODS Participants, primiparous women 1 year after vaginal delivery, underwent the Pelvic Organ Prolapse Quantification examination, measurement of IAP via a vaginal sensor while lifting a weighted car seat, pelvic floor muscle force assessment using an instrumented speculum, grip strength using a hand dynamometer, and trunk flexor endurance by holding an isometric contraction while maintaining a 60-degree angle to the table. We dichotomized pelvic floor support as worse (greatest descent of the anterior, posterior, or apical vagina during maximal strain at or below the hymen) versus better (all points above the hymen). RESULTS Of 825 participants eligible after delivery, 593 (71.9%) completed a 1-year study visit. Mean (SD) age was 29.6 (5.0) years. One year postpartum, 55 (9.3%) demonstrated worse support. There were no differences in IAP during lifting or in other measures of pelvic floor loading between women with better and worse support. In multivariable analyses, neither grip strength nor pelvic floor muscle force modified the effect of IAP on support. In women with trunk flexor endurance duration ≥13 minutes, the odds of worse support increased significantly as IAP increased. No fitness measure modified the effect of other measures of pelvic floor loading on support. CONCLUSIONS Primiparous women with higher IAP during lifting and greater muscular fitness did not have reduced odds of worse pelvic floor support compared with those with lower IAP at the same muscular fitness.
