Decision Aid Video for Treatment Selection in Latinas With Symptomatic Pelvic Organ Prolapse: A Randomized Pilot Study.

OBJECTIVES: To assess impact of a decision aid video in Latina patients with symptomatic pelvic organ prolapse (POP) on knowledge, satisfaction and decisional conflict related to initial treatment selection. METHODS: Pilot study with randomized prospective design. Thirty Latina women with symptomatic POP were randomized to a decision aid intervention plus standard care (N = 15) or standard care alone (N = 15) group. Decision aid intervention consisted of a 10-minute video presented at time of initial evaluation for POP. Outcome measures included the Prolapse and Incontinence Knowledge Quiz ("Knowledge"), the Satisfaction with Decision ("Satisfaction") and Decisional Conflict (DCS) scales, and were assessed at 4 different timepoints: after initial visit, and at 1, 3 and 6 months after. Data was analyzed using repeated-measures ANOVA and pairwise between-group comparisons. RESULTS: Demographic and baseline data were similar between groups. There was a significant interaction between groups and time on the Knowledge scores (P = 0.03). Knowledge scores were higher at the initial visit in the intervention group (10.6 ± 0.8 vs 9.53 ± 1.4, P = 0.014). Satisfaction scores were lower in the intervention group on longitudinal analysis, indicating higher satisfaction (P = 0.02). There was no difference on overall Decisional Conflict scores between groups. The intervention group had lower scores on the "effective decision" DCS subscale at 3 and 6 months and "informed" DCS subscale at 3 months. CONCLUSIONS: A decision aid video intervention in Latina women with POP used at the time of initial evaluation may help the patient make a more informed treatment decision by increasing condition-related knowledge and lead to greater long-term satisfaction.

Effects of vaginal conjugated equine estrogens and ospemifene on the rat vaginal wall and lower urinary tract.

Although the positive effects of vaginal estrogens and the selective estrogen receptor modulator, ospemifene (OS), on the vaginal epithelium are well recognized, less is known regarding the effects of these therapies on the lower urinary tract or vaginal muscularis. Clinical evidence suggests that vaginally administered estrogen may improve overactive bladder-related symptoms. The objective of this study was to compare the effects of OS, vaginal conjugated equine estrogens (CEE), or both on the vaginal wall and lower urinary tract in a rat model of menopause. Contractile force of the bladder neck, dome, and external urethral sphincter at optimal field stimulation did not differ significantly among treatment groups. Pharmacologic responses to atropine, carbachol, and potassium chloride were similar among groups. Vaginal epithelial thickness and differentiation were differentially regulated by CEE or OS. Ospemifene altered epithelial differentiation pathways in vaginal epithelium in a unique way, and these effects were additive with local CEE. Unless contraindicated, the beneficial effects of vaginal CEE on the vaginal wall outweigh those of OS.

Effect of vaginal or systemic estrogen on dynamics of collagen assembly in the rat vaginal wall.

The objective of this study was to compare the effects of systemic and local estrogen treatment on collagen assembly and biomechanical properties of the vaginal wall. Ovariectomized nulliparous rats were treated with estradiol or conjugated equine estrogens (CEEs) either systemically, vaginal CEE, or vaginal placebo cream for 4 wk. Low-dose local CEE treatment resulted in increased vaginal epithelial thickness and significant vaginal growth without uterine hyperplasia. Furthermore, vaginal wall distensibility increased without compromise of maximal force at failure. Systemic estradiol resulted in modest increases in collagen type I with no change in collagen type III mRNA. Low-dose vaginal treatment, however, resulted in dramatic increases in both collagen subtypes whereas moderate and high dose local therapies were less effective. Consistent with the mRNA results, low-dose vaginal estrogen resulted in increased total and cross-linked collagen content. The inverse relationship between vaginal dose and collagen expression may be explained in part by progressive downregulation of estrogen receptor-alpha mRNA with increasing estrogen dose. We conclude that, in this menopausal rat model, local estrogen treatment increased total and cross-linked collagen content and markedly stimulated collagen mRNA expression in an inverse dose-effect relationship. High-dose vaginal estrogen resulted in downregulation of estrogen receptor-alpha and loss of estrogen-induced increases in vaginal collagen. These results may have important clinical implications regarding the use of local vaginal estrogen therapy and its role as an adjunctive treatment in women with loss of vaginal support.
