RESUMO
BACKGROUND: Among women with symptomatic uterovaginal prolapse undergoing vaginal surgery in the Vaginal hysterectomy with Native Tissue Vault Suspension vs Sacrospinous Hysteropexy with Graft Suspension (Study for Uterine Prolapse Procedures Randomized Trial) trial, sacrospinous hysteropexy with graft (hysteropexy) resulted in a lower composite surgical failure rate than vaginal hysterectomy with uterosacral suspension over 5 years. OBJECTIVE: This study aimed to identify factors associated with the rate of surgical failure over 5 years among women undergoing sacrospinous hysteropexy with graft vs vaginal hysterectomy with uterosacral suspension for uterovaginal prolapse. STUDY DESIGN: This planned secondary analysis of a comparative effectiveness trial of 2 transvaginal apical suspensions (NCT01802281) defined surgical failure as either retreatment of prolapse, recurrence of prolapse beyond the hymen, or bothersome prolapse symptoms. Baseline clinical and sociodemographic factors for eligible participants receiving the randomized surgery (N=173) were compared across categories of failure (≤1 year, >1 year, and no failure) with rank-based tests. Factors with adequate prevalence and clinical relevance were assessed for minimally adjusted bivariate associations using piecewise exponential survival models adjusting for randomized apical repair and clinical site. The multivariable model included factors with bivariate P<.2, additional clinically important variables, apical repair, and clinical site. Backward selection determined final retained risk factors (P<.1) with statistical significance evaluated by Bonferroni correction (P<.005). Final factors were assessed for interaction with type of apical repair at P<.1. Association is presented by adjusted hazard ratios and further illustrated by categorization of risk factors. RESULTS: In the final multivariable model, body mass index (increase of 5 kg/m2: adjusted hazard ratio, 1.7; 95% confidence interval, 1.3-2.2; P<.001) and duration of prolapse symptoms (increase of 1 year: adjusted hazard ratio, 1.1; 95% confidence interval, 1.0-1.1; P<.005) were associated with composite surgical failure, where rates of failure were 2.9 and 1.8 times higher in women with obesity and women who are overweight than women who have normal weight and women who are underweight (95% confidence intervals, 1.5-5.8 and 0.9-3.5) and 3.0 times higher in women experiencing >5 years prolapse symptoms than women experiencing ≤5 years prolapse symptoms (95% confidence interval, 1.8-5.0). Sacrospinous hysteropexy with graft had a lower rate of failure than hysterectomy with uterosacral suspension (adjusted hazard ratio, 0.6; 95% confidence interval, 0.4-1.0; P=.05). The interaction between symptom duration and apical repair (P=.07) indicated that failure was less likely after hysteropexy than hysterectomy for those with ≤5 years symptom duration (adjusted hazard ratio, 0.5; 95% confidence interval, 0.2-0.9), but not for those with >5 years symptom duration (adjusted hazard ratio, 1.0; 95% confidence interval 0.5-2.1). CONCLUSION: Obesity and duration of prolapse symptoms have been determined as risk factors associated with surgical failure over 5 years from transvaginal prolapse repair, regardless of approach. Providers and patients should consider these modifiable risk factors when discussing treatment plans for bothersome prolapse.

INTRODUCTION AND HYPOTHESIS: Factors that contribute to reoperation and surgical approaches for the management of recurrent uterovaginal prolapse after vaginal mesh hysteropexy (mesh hysteropexy) are unknown. We aimed to describe surgical management of pelvic organ prolapse recurrence after vaginal mesh hysteropexy, and patient characteristics in those who chose reoperation. METHODS: This is a descriptive analysis of women who experienced treatment failure within 5 years of mesh hysteropexy in a multi-site randomized trial. The composite definition of treatment failure included retreatment (pessary or reoperation), prolapse beyond the hymen, or bothersome prolapse symptoms. Characteristics of those pursuing and not pursuing repeat prolapse surgery, measures of prolapse, and symptom severity are described. RESULTS: Over 5-year follow up, 31/91 (34%) of the hysteropexy group met treatment failure criteria. All seven women who pursued reoperation reported bothersome prolapse symptoms; six were anatomic failures. Most seeking reoperation were early treatment failures; six (86%) by the 12-month visit and all by the 18-month visit. Compared to those electing expectant management, those pursuing reoperation had more apical prolapse, POP-Q point C median (IQR) -5.5 (-6.0, -4.0) cm versus +1.0 (-1.0, 3.0) cm respectively. Hysterectomy was performed in 6/7 reoperations (three vaginal, three endoscopic), with apical suspension in 5/6 hysterectomies. One participant with posterior compartment prolapse underwent transvaginal enterocele plication, uterosacral ligament suspension with posterior colpoperineorrhaphy. At a mean surgical follow-up of 34.3 (15.8) months, all women remained without anatomic or symptomatic failure. CONCLUSIONS: When recurrent prolapse after mesh hysteropexy occurred, most women did not choose reoperation. Those who pursued surgery experienced more significant apical prolapse and were universally symptomatic. CLINICAL TRIAL IDENTIFICATION NUMBER: NCT01802281.

OBJECTIVE: To evaluate whether the fetal linear growth effects of maternal nutrition supplementation would be maintained through 6 months postnatal age. STUDY DESIGN: The Women First trial was a multicountry, individually randomized clinical trial that compared the impact of maternal nutrition supplementation initiated preconception (Arm 1) vs at â¼11 weeks of gestation (Arm 2), vs no supplement (Arm 3); the intervention was discontinued at delivery. Trial sites were in Democratic Republic of Congo, Guatemala, India, and Pakistan. Analysis includes 2421 infants born to 2408 randomized women. Primary outcome was the trajectory of length-for-age z scores (LAZ) by arm, based on assessments at birth and 1, 3, and 6 months. We fitted longitudinal models on growth from birth to 6 months using generalized estimating equations; maternal intervention effects were evaluated, adjusting for site and baseline maternal covariates. RESULTS: Linear growth for Arms 1 and 2 was statistically greater than for Arm 3 in 3 of the 4 countries, with average pairwise mean differences in LAZ of 0.25 (95% CI 0.15-0.35; P < .001) and 0.19 (95% CI 0.09-0.28; P < .001), respectively. Compared with Arm 3, average overall adjusted relative risks (95% CI) for stunting (LAZ <-2) were lower for Arms 1 and 2: 0.76 (0.66-0.87; P < .001) and 0.77 (0.67-0.88; P < .001), respectively. CONCLUSIONS: Improved linear growth in early infancy observed for the 2 intervention arms supports the critical importance of maternal nutrition before conception and in the early phase of gestation.

BACKGROUND: The ideal measure of success after surgery for pelvic organ prolapse has long been debated. Historically, strict definitions based on anatomic perfection have dominated the literature. However, the importance of patient-centered perception of outcomes is equally or more important when comparing the success of various prolapse surgeries. Understanding the limitations of existing outcome definitions will guide surgical outcome reporting and comparisons of pelvic organ prolapse surgeries. OBJECTIVE: This study aimed to describe the relationships and overlap among the participants who met the anatomic, subjective, and retreatment definitions of success or failure after pelvic organ prolapse surgery; demonstrate rates of transition between success and failure over time; and compare scores from the Pelvic Organ Prolapse Distress Inventory, Short-Form Six-Dimension health index, and quality-adjusted life years among these definitions. STUDY DESIGN: Definitions of surgical success were evaluated at 3 or 6, 12, 24, 36, 48, and 60 months after surgery for ≥stage II pelvic organ prolapse in a cohort of women (N=1250) from 4 randomized clinical trials conducted by the Eunice Kennedy Shriver National Institute of Child Health and Human Development Pelvic Floor Disorders Network. Surgical failure was defined by a composite measure requiring 1 or more of (1) anatomic failure (Pelvic Organ Prolapse Quantification point Ba, Bp, or C of >0), (2) subjective failure (presence of bothersome vaginal bulge symptoms), or (3) pessary or surgical retreatment for pelvic organ prolapse. Pelvic Organ Prolapse Distress Inventory, Short-Form Six-Dimension health index, and quality-adjusted life years were compared among participants who met a variety of definitions of success and failure including novel "intermittent" success and failure over time. RESULTS: Among the 433 of 1250 women (34.6%) who had surgical failure outcomes at ≥1 time point, 85.5% (370 of 433) met only 1 component of the composite outcome at the assessment of initial failure (anatomic failure, 46.7% [202 of 433]; subjective failure, 36.7% [159 of 433]; retreatment, 2.1% [9 of 433]). Only 12.9% (56 of 433) met the criteria for both for anatomic and subjective failure. Despite meeting the criteria for failure in primary study reporting, 24.2% of these (105 of 433) transitioned between success and failure during follow-up, of whom 83.8% (88 of 105) met the criteria for success at their last follow-up. There were associations between success or failure classification and the 1- and 2-year quality-adjusted life years and a time-varying group effect on Pelvic Organ Prolapse Distress Inventory and Short-Form Six-Dimension health index scores. CONCLUSION: True failure rates after prolapse surgery may be overestimated in the current literature. Only 13% of clinical trial subjects initially met both subjective and objective criteria for failure. Approximately one-quarter of failures were intermittent and transitioned between success and failure over time, with most intermittent failures being in a state of "surgical success" at their last follow-up. Current composite definitions of success or failure may result in the overestimation of surgical failure rates, potentially explaining, in part, the discordance with low retreatment rates after pelvic organ prolapse surgery.

BACKGROUND: Vaginal hysterectomy with suture apical suspension is commonly performed for uterovaginal prolapse. Sacrospinous hysteropexy with graft (vaginal mesh hysteropexy) is an alternative, although in 2019 the Food and Drug Administration removed this mesh product from the United States market. OBJECTIVE: Our objective was to compare the efficacy and adverse events of these 2 procedures. STUDY DESIGN: At 9 clinical sites in the United States National Institutes of Health and National Institute of Child Health and Human Development Pelvic Floor Disorders Network, 183 postmenopausal women requesting vaginal surgery for symptomatic uterovaginal prolapse were enrolled in a multisite randomized superiority clinical trial, comparing a sacrospinous hysteropexy with graft (hysteropexy) with a vaginal hysterectomy with uterosacral ligament suspension (hysterectomy). Participants consented to remain masked to treatment assignment for the study duration. Study visits were conducted at 6-month intervals through 60 months. The primary treatment failure composite outcome (retreatment of prolapse, prolapse beyond the hymen, or prolapse symptoms) was evaluated with survival modeling. Secondary outcomes included complications or adverse events, individual anatomic measures of the pelvic organ prolapse quantification examination, and presence, severity, and impact and bother of prolapse, urinary, bowel, and pain symptoms as measured by validated questionnaires. The 3-year published results suggested better primary outcomes with sacrospinous hysteropexy with graft, but the differences were not statistically significant (P=.06). This study reports the 5-year outcomes. RESULTS: A total of 183 women with a mean age of 66 years were randomized between April 2013 and February 2015; 93 were randomized to hysteropexy and 90 were randomized to hysterectomy. Notably, 175 were included in the trial, and 156 (89%) completed the 5-year follow-up. The primary outcome showed fewer failures for hysteropexy than hysterectomy through 5 years (adjusted hazard ratio, 0.58; 95% confidence interval, 0.36-0.94; P=.03), with failure rates of 37% vs 54%, respectively, resulting in a difference of -18% (95% confidence interval, -33% to -3%) at 5 years. With the exception of the Urogenital Distress Inventory, no group differences were demonstrated in patient-reported pelvic floor symptoms, prolapse symptoms, bowel function symptoms, general quality of life, body image, or pelvic pain. At their last visit through 5 years, 70% of participants (129 of 183) reported they remained masked to their treatment with no difference in masking between groups. Adverse events for hysteropexy vs hysterectomy included mesh exposure (8% vs 0%), granulation tissue after 12 weeks (1% vs 12%), and suture exposure after 12 weeks (3% vs 21%), respectively. CONCLUSION: Among women with symptomatic uterovaginal prolapse undergoing vaginal surgery, sacrospinous hysteropexy with graft resulted in a lower composite failure rate than vaginal hysterectomy through 5 years. There were no meaningful differences in patient-reported outcomes between groups. Our results suggest that this vaginal mesh hysteropexy procedure should be made available to patients.

BACKGROUND: Treatment outcomes after pelvic organ prolapse surgery are often presented as dichotomous "success or failure" based on anatomic and symptom criteria. However, clinical experience suggests that some women with outcome "failures" are asymptomatic and perceive their surgery to be successful and that other women have anatomic resolution but continue to report symptoms. Characterizing failure types could be a useful step to clarify definitions of success, understand mechanisms of failure, and identify individuals who may benefit from specific therapies. OBJECTIVE: This study aimed to identify clusters of women with similar failure patterns over time and assess associations among clusters and the Pelvic Organ Prolapse Distress Inventory, Short-Form Six-Dimension health index, Patient Global Impression of Improvement, patient satisfaction item questionnaire, and quality-adjusted life-year. STUDY DESIGN: Outcomes were evaluated for up to 5 years in a cohort of participants (N=709) with stage ≥2 pelvic organ prolapse who underwent surgical pelvic organ prolapse repair and had sufficient follow-up in 1 of 4 multicenter surgical trials conducted by the Eunice Kennedy Shriver National Institute of Child Health and Human Development Pelvic Floor Disorders Network. Surgical success was defined as a composite measure requiring anatomic success (Pelvic Organ Prolapse Quantification system points Ba, Bp, and C of ≤0), subjective success (absence of bothersome vaginal bulge symptoms), and absence of retreatment for pelvic organ prolapse. Participants who experienced surgical failure and attended ≥4 visits from baseline to 60 months after surgery were longitudinally clustered, accounting for similar trajectories in Ba, Bp, and C and degree of vaginal bulge bother; moreover, missing data were imputed. Participants with surgical success were grouped into a separate cluster. RESULTS: Surgical failure was reported in 276 of 709 women (39%) included in the analysis. Failures clustered into the following 4 mutually exclusive subgroups: (1) asymptomatic intermittent anterior wall failures, (2) symptomatic intermittent anterior wall failures, (3) asymptomatic intermittent anterior and posterior wall failures, and (4) symptomatic all-compartment failures. Each cluster had different bulge symptoms, anatomy, and retreatment associations with quality of life outcomes. Asymptomatic intermittent anterior wall failures (n=150) were similar to surgical successes with Ba values that averaged around -1 cm but fluctuated between anatomic success (Ba≤0) and failure (Ba>0) over time. Symptomatic intermittent anterior wall failures (n=82) were anatomically similar to asymptomatic intermittent anterior failures, but women in this cluster persistently reported bothersome bulge symptoms and the lowest quality of life, Short-Form Six-Dimension health index scores, and perceived success. Women with asymptomatic intermittent anterior and posterior wall failures (n=28) had the most severe preoperative pelvic organ prolapse but the lowest symptomatic failure rate and retreatment rate. Participants with symptomatic all-compartment failures (n=16) had symptomatic and anatomic failure early after surgery and the highest retreatment of any cluster. CONCLUSION: In particular, the following 4 clusters of pelvic organ prolapse surgical failure were identified in participants up to 5 years after pelvic organ prolapse surgery: asymptomatic intermittent anterior wall failures, symptomatic intermittent anterior wall failures, asymptomatic intermittent anterior and posterior wall failures, and symptomatic all-compartment failures. These groups provide granularity about the nature of surgical failures after pelvic organ prolapse surgery. Future work is planned for predicting these distinct outcomes using patient characteristics that can be used for counseling women individually.

BACKGROUND: Prolapse recurrence after transvaginal surgical repair is common; however, its mechanisms are ill-defined. A thorough understanding of how and why prolapse repairs fail is needed to address their high rate of anatomic recurrence and to develop novel therapies to overcome defined deficiencies. OBJECTIVE: This study aimed to identify mechanisms and contributors of anatomic recurrence after vaginal hysterectomy with uterosacral ligament suspension (native tissue repair) vs transvaginal mesh (VM) hysteropexy surgery for uterovaginal prolapse. STUDY DESIGN: This multicenter study was conducted in a subset of participants in a randomized clinical trial by the Eunice Kennedy Shriver National Institute of Child Health and Human Development Pelvic Floor Disorders Network. Overall, 94 women with uterovaginal prolapse treated via native tissue repair (n=48) or VM hysteropexy (n=46) underwent pelvic magnetic resonance imaging at rest, maximal strain, and poststrain rest (recovery) 30 to 42 months after surgery. Participants who desired reoperation before 30 to 42 months were imaged earlier to assess the impact of the index surgery. Using a novel 3-dimensional pelvic coordinate system, coregistered midsagittal images were obtained to assess study outcomes. Magnetic resonance imaging-based anatomic recurrence (failure) was defined as prolapse beyond the hymen. The primary outcome was the mechanism of failure (apical descent vs anterior vaginal wall elongation), including the frequency and site of failure. Secondary outcomes included displacement of the vaginal apex and perineal body and change in the length of the anterior wall, posterior wall, vaginal perimeter, and introitus of the vagina from rest to strain and rest to recovery. Group differences in the mechanism, frequency, and site of failure were assessed using the Fisher exact tests, and secondary outcomes were compared using Wilcoxon rank-sum tests. RESULTS: Of the 88 participants analyzed, 37 (42%) had recurrent prolapse (VM hysteropexy, 13 of 45 [29%]; native tissue repair, 24 of 43 [56%]). The most common site of failure was the anterior compartment (VM hysteropexy, 38%; native tissue repair, 92%). The primary mechanism of recurrence was apical descent (VM hysteropexy, 85%; native tissue repair, 67%). From rest to strain, failures (vs successes) had greater inferior displacement of the vaginal apex (difference, -12 mm; 95% confidence interval, -19 to -6) and perineal body (difference, -7 mm; 95% confidence interval, -11 to -4) and elongation of the anterior vaginal wall (difference, 12 mm; 95% confidence interval, 8-16) and vaginal introitus (difference, 11 mm; 95% confidence interval, 7-15). CONCLUSION: The primary mechanism of prolapse recurrence following vaginal hysterectomy with uterosacral ligament suspension or VM hysteropexy was apical descent. In addition, greater inferior descent of the vaginal apex and perineal body, lengthening of the anterior vaginal wall, and increased size of the vaginal introitus with strain were associated with anatomic failure. Further studies are needed to provide additional insight into the mechanism by which these factors contribute to anatomic failure.

BACKGROUND: Posterior repairs and perineorrhaphies are often performed in prolapse surgery to reduce the size of the genital hiatus. The benefit of an adjuvant posterior repair at the time of sacrospinous ligament fixation or uterosacral ligament suspension is unknown. OBJECTIVE: We aimed to determine whether an adjuvant posterior repair at transvaginal apical suspension is associated with improved surgical success. MATERIALS AND METHODS: This secondary analysis of Operations and Pelvic Muscle Training in the Management of Apical Support Loss (OPTIMAL) trial compared 24-month outcomes in 190 participants who had a posterior repair (posterior repair group) and 184 who did not (no posterior repair group) at the time of sacrospinous ligament fixation or uterosacral ligament suspension. Concomitant posterior repair was performed at the surgeon's discretion. Primary composite outcome of "surgical success" was defined as no prolapse beyond the hymen, point C ≤ -2/3 total vaginal length, no bothersome bulge symptoms, and no retreatment at 24 months. The individual components were secondary outcomes. Propensity score methods were used to build models that balanced posterior repair group and the no posterior repair group for ethnographic factors and preoperative Pelvic Organ Prolapse Quantification values. Adjusted odds ratios were calculated to predict surgical success based on the performance of a posterior repair. Groups were also compared with unadjusted χ2 analyses. An unadjusted probability curve was created for surgical success as predicted by preoperative genital hiatus. RESULTS: Women in the posterior repair group were less likely to be Hispanic or Latina, and were more likely to have had a prior hysterectomy and to be on estrogen therapy. The groups did not differ with respect to preoperative Pelvic Organ Prolapse Quantification stage; however, subjects in the posterior repair group had significantly greater preoperative posterior wall prolapse. There were no group differences in surgical success using propensity score methods (66.7% posterior repair vs 62.0% no posterior repair; adjusted odds ratio, 1.07; 95% confidence interval, 0.56-2.07; P = 0.83) or unadjusted test (66.2% posterior repair vs 61.7% no posterior repair; P = 0.47). Individual outcome measures of prolapse recurrence (bothersome bulge symptoms, prolapse beyond the hymen, or retreatment for prolapse) also did not differ by group. Similarly, there were no differences between groups in anatomic outcomes of any individual compartment (anterior, apical, or posterior) at 24 months. There was high variation in performance of posterior repair by surgeon (interquartile range, 15-79%). The unadjusted probability of overall success at 24 months, regardless of posterior repair, decreased with increasing genital hiatus, such that a genital hiatus of 4.5 cm was associated with 65.8% success (95% confidence interval, 60.1-71.1%). CONCLUSION: Concomitant posterior repair at sacrospinous ligament fixation or uterosacral ligament suspension was not associated with surgical success after adjusting for baseline covariates using propensity scores or unadjusted comparison. Posterior repair may not compensate for the pathophysiology that leads to enlarged preoperative genital hiatus, which remains prognostic of prolapse recurrence.

BACKGROUND: Little is known about short- and long-term pain and functional activity after surgery for pelvic organ prolapse. OBJECTIVE: The objectives of the study were to describe postoperative pain and functional activity after transvaginal native tissue reconstructive surgery with apical suspension and retropubic synthetic midurethral sling and to compare these outcomes between patients receiving 2 common transvaginal prolapse repairs, uterosacral ligament, and sacrospinous ligament vaginal vault suspension. STUDY DESIGN: This planned secondary analysis of a 2 × 2 factorial randomized trial included 374 women randomized to receive uterosacral (n = 188) or sacrospinous (n = 186) vaginal vault suspension to treat both stages 2-4 apical vaginal prolapse and stress urinary incontinence between 2008 and 2013 at 9 medical centers. Participants were also randomized to receive perioperative pelvic muscle therapy or usual care. All patients received transvaginal native tissue repairs and a midurethral sling. Participants completed the Surgical Pain Scales (0-10 numeric rating scales; higher scores = greater pain) and Activity Assessment Scale (0-100; higher score = higher activity) prior to surgery and at 2 weeks, 4-6 weeks, and 3 months postoperatively. The MOS 36-item Short-Form Health Survey was completed at baseline and 6, 12, and 24 months after surgery; the bodily pain, physical functioning, and role-physical subscales were used for this analysis (higher scores = less disability). Self-reported pain medication use was also collected. RESULTS: Before surgery, average pain at rest and during normal activity were (adjusted mean ± SE) 2.24 ± 0.23 and 2.76 ± 0.25; both increased slightly from baseline at 2 weeks (+0.65, P = .004, and +0.74, P = .007, respectively) and then decreased below baseline at 3 months (-0.87 and -1.14, respectively, P < .001), with no differences between surgical groups. Pain during exercise/strenuous activity and worst pain decreased below baseline levels at 4-6 weeks (-1.26, P = .014, and -0.95, P = .002) and 3 months (-1.97 and -1.50, P < .001) without differences between surgical groups. Functional activity as measured by the Activity Assessment Scale improved from baseline at 4-6 weeks (+9.24, P < .001) and 3 months (+13.79, P < .001). The MOS 36-item Short-Form Health Survey Bodily Pain, Physical Functioning, and Role-Physical Scales demonstrated significant improvements from baseline at 6, 12, and 24 months (24 months: +5.62, +5.79, and +4.72, respectively, P < .001 for each) with no differences between groups. Use of narcotic pain medications was reported by 14.3% of participants prior to surgery and 53.7% at 2 and 26.1% at 4-6 weeks postoperatively; thereafter use was similar to baseline rates until 24 months when it decreased to 6.8%. Use of nonnarcotic pain medication was reported by 48.1% of participants prior to surgery, 68.7% at 2 weeks, and similar to baseline at 3 months; thereafter use dropped steadily to 26.6% at 2 years. Uterosacral ligament suspension resulted in less new or worsening buttock pain than sacrospinous suspension at 4-6 weeks postoperatively (4.6% vs 10.5%, P = .043) but no difference in groin or thigh pain. CONCLUSION: Pain and functional activity improve for up to 2 years after native tissue reconstructive surgery with uterosacral or sacrospinous vaginal vault suspension and midurethral sling for stages 2-4 pelvic organ prolapse. On average, immediate postoperative pain is low and improves to below baseline levels by 4-6 weeks.

Importance: Vaginal hysterectomy with suture apical suspension is commonly performed for uterovaginal prolapse. Transvaginal mesh hysteropexy is an alternative option. Objective: To compare the efficacy and adverse events of vaginal hysterectomy with suture apical suspension and transvaginal mesh hysteropexy. Design, Setting, Participants: At 9 clinical sites in the US Pelvic Floor Disorders Network, 183 postmenopausal women with symptomatic uterovaginal prolapse were enrolled in a randomized superiority clinical trial between April 2013 and February 2015. The study was designed for primary analysis when the last randomized participant reached 3 years of follow-up in February 2018. Interventions: Ninety-three women were randomized to undergo vaginal mesh hysteropexy and 90 were randomized to undergo vaginal hysterectomy with uterosacral ligament suspension. Main Outcomes and Measures: The primary treatment failure composite outcome (re-treatment of prolapse, prolapse beyond the hymen, or prolapse symptoms) was evaluated with survival models. Secondary outcomes included operative outcomes and adverse events, and were evaluated with longitudinal models or contingency tables as appropriate. Results: A total of 183 participants (mean age, 66 years) were randomized, 175 were included in the trial, and 169 (97%) completed the 3-year follow-up. The primary outcome was not significantly different among women who underwent hysteropexy vs hysterectomy through 48 months (adjusted hazard ratio, 0.62 [95% CI, 0.38-1.02]; P = .06; 36-month adjusted failure incidence, 26% vs 38%). Mean (SD) operative time was lower in the hysteropexy group vs the hysterectomy group (111.5 [39.7] min vs 156.7 [43.9] min; difference, -45.2 [95% CI, -57.7 to -32.7]; P = <.001). Adverse events in the hysteropexy vs hysterectomy groups included mesh exposure (8% vs 0%), ureteral kinking managed intraoperatively (0% vs 7%), granulation tissue after 12 weeks (1% vs 11%), and suture exposure after 12 weeks (3% vs 21%). Conclusions and Relevance: Among women with symptomatic uterovaginal prolapse undergoing vaginal surgery, vaginal mesh hysteropexy compared with vaginal hysterectomy with uterosacral ligament suspension did not result in a significantly lower rate of the composite prolapse outcome after 3 years. However, imprecision in study results precludes a definitive conclusion, and further research is needed to assess whether vaginal mesh hysteropexy is more effective than vaginal hysterectomy with uterosacral ligament suspension. Trial Registration: ClinicalTrials.gov Identifier: NCT01802281.

IMPORTANCE: The impact of a persistently enlarged genital hiatus (GH) after vaginal hysterectomy with uterosacral ligament suspension on prolapse outcomes is currently unclear. OBJECTIVES: This secondary analysis of the Study of Uterine Prolapse Procedures Randomized trial was conducted among participants who underwent vaginal hysterectomy with uterosacral ligament suspension. We hypothesized that women with a persistently enlarged GH size would have a higher proportion of prolapse recurrence. STUDY DESIGN: Women who underwent vaginal hysterectomy with uterosacral ligament suspension as part of the Study of Uterine Prolapse Procedures Randomized trial (NCT01802281) were divided into 3 groups based on change in their preoperative to 4- to 6-week postoperative GH measurements: (1) persistently enlarged GH, 2) improved GH, or (3) stably normal GH. Baseline characteristics and 2-year surgical outcomes were compared across groups. A logistic regression model for composite surgical failure controlling for advanced anterior wall prolapse and GH group was fitted. RESULTS: This secondary analysis included 81 women. The proportion with composite surgical failure was significantly higher among those with a persistently enlarged GH (50%) compared with a stably normal GH (12%) with an unadjusted risk difference of 38% (95% confidence interval, 4%-68%). When adjusted for advanced prolapse in the anterior compartment at baseline, the odds of composite surgical failure was 6 times higher in the persistently enlarged GH group compared with the stably normal group (95% confidence interval, 1.0-37.5; P = 0.06). CONCLUSION: A persistently enlarged GH after vaginal hysterectomy with uterosacral ligament suspension for pelvic organ prolapse may be a risk factor for recurrent prolapse.

BACKGROUND: Maternal nutrition in preconception and early pregnancy influences fetal growth. Evidence for effects of prenatal maternal nutrition on early child development (ECD) in low-income and middle-income countries is limited. OBJECTIVES: To examine impact of maternal nutrition supplementation initiated prior to or during pregnancy on ECD, and to examine potential association of postnatal growth with ECD domains. DESIGN: Secondary analysis regarding the offspring of participants of a maternal multicountry, individually randomised trial. SETTING: Rural Democratic Republic of the Congo, Guatemala, India and Pakistan. PARTICIPANTS: 667 offspring of Women First trial participants, aged 24 months. INTERVENTION: Maternal lipid-based nutrient supplement initiated preconceptionally (arm 1, n=217), 12 weeks gestation (arm 2, n=230) or not (arm 3, n=220); intervention stopped at delivery. MAIN OUTCOME MEASURES: The INTERGROWTH-21st Neurodevelopment Assessment (INTER-NDA) cognitive, language, gross motor, fine motor, positive and negative behaviour scores; visual acuity and contrast sensitivity scores and auditory evoked response potentials (ERP). Anthropometric z-scores, family care indicators (FCI) and sociodemographic variables were examined as covariates. RESULTS: No significant differences were detected among the intervention arms for any INTER-NDA scores across domains, vision scores or ERP potentials. After adjusting for covariates, length-for-age z-score at 24 months (LAZ24), socio-economic status, maternal education and FCI significantly predicted vision and INTER-NDA scores (R2=0.11-0.38, p<0.01). CONCLUSIONS: Prenatal maternal nutrition supplementation was not associated with any neurodevelopmental outcomes at age 2 years. Maternal education, family environment and LAZ24 predicted ECD. Interventions addressing multiple components of the nurturing care model may offer greatest impact on children's developmental potential. TRIAL REGISTRATION NUMBER: NCT01883193.

IMPORTANCE: Many health care providers place concomitant midurethral slings during pelvic organ prolapse repair, yet growing evidence supports staged midurethral sling placement. OBJECTIVES: The aim of this study was to compare urinary function after transvaginal uterovaginal prolapse repair with and without midurethral sling. STUDY DESIGN: Secondary analysis of the Study of Uterine Prolapse Procedures Randomized Trial (hysterectomy with uterosacral ligament suspension vs mesh hysteropexy). Our primary outcome was Urinary Distress Inventory score (UDI-6) through 5 years compared between women with and without a concomitant sling within prolapse repair arms. Sling effect was adjusted for select clinical variables and interaction terms (α = .05). RESULTS: The sling group included 90 women (43 hysteropexy, 47 hysterectomy), and the no-sling group included 93 women (48 hysteropexy, 45 hysterectomy). At baseline, the sling group reported more bothersome stress (66% vs 36%, P < 0.001) and urgency incontinence (69% vs 48%, P = 0.007). For hysteropexy, there were no significant long-term differences in UDI-6 scores or bothersome urine leakage between sling groups. For hysterectomy, women with sling had better UDI-6 scores across time points (adjusted mean difference, -5.1; 95% confidence interval [CI], -9.9 to -0.2); bothersome stress and urgency leakage were less common in the sling group (stress adjusted odds ratio, 0.1 [95% CI, 0.0-0.4]; urge adjusted odds ratio, 0.5 [95% CI, 0.2-1.0]). Treatment for stress incontinence over 5 years was similar in the sling (7.9%) versus no-sling (7.6%) groups. CONCLUSIONS: Five-year urinary outcomes of concomitant midurethral sling may vary by type of transvaginal prolapse surgery, with possible benefit of midurethral sling at the time of vaginal hysterectomy with apical suspension but not after mesh hysteropexy.

OBJECTIVES: There is a paucity of data on postoperative exercise and how it relates to surgical failure, specifically after midurethral sling (MUS) surgery. We aimed to assess if women with higher self-reported activity levels as measured by strenuous exercise are more likely to experience stress urinary incontinence (SUI) symptoms after MUS than women with lower self-reported activity. METHODS: This is a secondary analysis of Operations and Pelvic Muscle Training in the Management of Apical Support Loss: the OPTIMAL Trial, a randomized trial comparing sacrospinous ligament suspension versus uterosacral ligament suspension, both with concomitant retropubic MUS. Participants completed a validated assessment of activity preoperatively and postoperatively. Women in the upper quartile for strenuous exercise (≥90 minutes per week) were compared with the remaining participants. Symptomatic SUI was defined as retreatment or reoperation for SUI and/or any positive response to Pelvic Floor Disorders Inventory stress incontinence questions 20 to 22. RESULTS: A total of 351 participants in the OPTIMAL study received MUS along with their prolapse repair and had postoperative exercise and Pelvic Floor Disorders Inventory data. At 2 years, 87 (29%) of 305 exercised strenuously for at least 90 minutes per week, and 63 (23%) of 277 experienced SUI. Women who were less active at 2 years were significantly more likely to experience SUI than women who were more active (26.6% vs 12.8%, P = 0.0138). CONCLUSIONS: In this study, symptomatic SUI occurred more frequently in women with lower self-reported exercise levels 2 years after MUS surgery.

OBJECTIVE: To assess whether resting genital hiatus, perineal body, and total vaginal length measured intraoperatively at the conclusion of surgery are associated with prolapse recurrence 2 years after native tissue pelvic organ prolapse reconstruction. METHODS: This ancillary analysis of the OPTIMAL (Operations and Pelvic Muscle Training in the Management of Apical Support Loss) trial included women who had an immediate postoperative pelvic organ prolapse quantification (POP-Q) examination and 2-year follow-up. Primary outcome was bothersome bulge symptoms. Secondary outcomes were anatomic failure, surgical failure (either anatomic failure or bothersome bulge symptoms), and sexual function. Descriptive statistics assessed relationships between postprocedure POP-Q measures and these four outcomes. Multivariable models were fit to the data to control for baseline differences in bivariate comparisons. Receiver operating characteristic curves were generated to identify an optimal genital hiatus cut point associated with bothersome bulge, and this threshold was explored. RESULTS: This analysis included 368 participants. Bivariate analyses identified age, body mass index, vaginal deliveries, baseline genital hiatus, perineal body, and advanced POP-Q stage (3 or higher vs 2) as clinically relevant variables to include in multivariable models. After adjusting for these variables, the association between immediate postoperative genital hiatus and bothersome bulge (adjusted odds ratio [aOR] 1.4; 95% CI 0.9-2.1) was not significant at the P<.05 level; however, immediate postoperative genital hiatus was associated with anatomic (aOR 1.6; 95% CI 1.1-2.3) and surgical failure (aOR 1.5; 95% CI 1.0-2.1). Immediate postoperative genital hiatus of 3.5 cm was the selected cutoff (area under the curve 0.58, 95% CI 0.50-0.66 from the bothersome bulge model). Women with genital hiatus 3.5 cm or greater were more likely to have anatomic and surgical failures at 2 years. No POP-Q measures were correlated with 2-year sexual function. CONCLUSION: A larger immediate postoperative genital hiatus measurement of 3.5 cm or greater is not associated with bothersome bulge symptoms or sexual dysfunction but is associated with anatomic and surgical failures 2 years after native tissue vaginal reconstructive surgery.

OBJECTIVE: To describe sexual activity and risks for dyspareunia after pelvic organ prolapse surgery. METHODS: This was a secondary analysis of data from four randomized trials conducted between 2002 and 2018. Standard assessments and validated measures of sexual function were assessed at baseline and at 12 months postoperatively. Anterior apical surgeries were grouped by approach: transvaginal native tissue repairs, transvaginal mesh or graft-augmented repairs, and abdominal sacrocolpopexy. Additional surgeries, which included posterior repair, hysterectomy, and slings, were analyzed. Bivariate analyses and logistic regression models identified risk factors for postoperative dyspareunia. RESULTS: Of the 1,337 women enrolled in the trials, 932 had sufficient outcome data to determine dyspareunia status. Of these before surgery, 445 (47.8%) were sexually active without dyspareunia, 89 (9.6%) were sexually active with dyspareunia, 93 (10.0%) were not sexually active owing to fear of dyspareunia, and 305 (32.7%) were not sexually active for other reasons. At 12 months, dyspareunia or fear of dyspareunia was present in 63 of 627 (10.0%); occurred de novo in 17 of 445 (3.8%) and resolved in 136 of 182 (74.7%). Multivariable regression demonstrated baseline dyspareunia as the only factor associated with postoperative dyspareunia (adjusted odds ratio 7.8, 95% CI 4.2-14.4). No other factors, including surgical approach, were significantly associated with postoperative dyspareunia. Too few had de novo dyspareunia to perform modeling. CONCLUSION: Dyspareunia is common in one in five women before undergoing prolapse surgery. Surgical repair resolves dyspareunia in three out of four women with low rates of de novo dyspareunia at less than 4%. Preoperative dyspareunia appears to be the only predictor of postoperative dyspareunia. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT00065845, NCT00460434, NCT00597935, and NCT01802281.

South Asia has >50% of the global burden of low birth weight (LBW). The objective was to determine the extent to which maternal nutrition interventions commenced before conception or in the 1st trimester improved fetal growth in this region. This was a secondary analysis of combined newborn anthropometric data for the South Asian sites (India and Pakistan) in the Women First Preconception Maternal Nutrition Trial. Participants were 972 newborn of mothers who were poor, rural, unselected on basis of nutritional status, and had been randomized to receive a daily lipid-based micronutrient supplement commencing ≥3 months prior to conception (Arm 1), in the 1st trimester (Arm 2), or not at all (Arm 3). An additional protein-energy supplement was provided if BMI <20 kg/m2 or gestational weight gain was less than guidelines. Gestational age was established in the 1st trimester and newborn anthropometry obtained <48-hours post-delivery. Mean differences at birth between Arm 1 vs. 3 were length +5.3mm and weight +89g. Effect sizes (ES) and relative risks (RR) with 95% CI for Arm 1 vs. 3 were: length-for-age Z-score (LAZ) +0.29 (0.11-0.46, p = 0.0011); weight-for-age Z-score (WAZ) +0.22 (0.07-0.37, p = 0.0043); weight-to-length-ratio-for-age Z-score (WLRAZ) +0.27 (0.06-0.48, p = 0.0133); LAZ<-2, 0.56 (0.38-0.82, p = 0.0032); WAZ <-2, 0.68 (0.53-0.88, p = 0.0028); WLRAZ <-2, 0.76 (0.64-0.89, p = 0.0011); small-for-gestational-age (SGA), 0.74 (0.66-0.83, p<0.0001); low birth weight 0.81 (0.66-1.00, p = 0.0461). For Arm 2 vs. 3, LAZ, 0.21 (0.04-0.38); WAZ <-2, 0.70 (0.53-0.92); and SGA, 0.88 (0.79-0.97) were only marginally different. ES or RR did not differ for preterm birth for either Arm 1 vs. 3 or 2 vs. 3. In conclusion, point estimates for both continuous and binary anthropometric outcomes were consistently more favorable when maternal nutrition supplements were commenced ≥3 months prior to conception indicating benefits to fetal growth of improving women's nutrition in this population.

OBJECTIVE: Among extremely preterm infants, we evaluated whether bevacizumab therapy compared with surgery for retinopathy of prematurity (ROP) is associated with adverse outcomes in early childhood. METHODS: This study was a retrospective analysis of prospectively collected data on preterm (22-26 + 6/7 weeks' gestational age) infants admitted to the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network centers who received bevacizumab or surgery exclusively for ROP. The primary outcome was death or severe neurodevelopmental impairment (NDI) at 18 to 26 months' corrected age (Bayley Scales of Infant and Toddler Development, Third Edition cognitive or motor composite score <70, Gross Motor Functional Classification Scale level ≥2, bilateral blindness or hearing impairment). RESULTS: The cohort (N = 405; 214 [53%] boys; median [interquartile range] gestational age: 24.6 [23.9-25.3] weeks) included 181 (45%) infants who received bevacizumab and 224 (55%) who underwent ROP surgery. Infants treated with bevacizumab had a lower median (interquartile range) birth weight (640 [541-709] vs 660 [572.5-750] g; P = .02) and longer durations of conventional ventilation (35 [21-58] vs 33 [18-49] days; P = .04) and supplemental oxygen (112 [94-120] vs 105 [84.5-120] days; P = .01). Death or severe NDI (adjusted odds ratio [aOR] 1.42; 95% confidence interval [CI] 0.94 to 2.14) and severe NDI (aOR 1.14; 95% CI 0.76 to 1.70) did not differ between groups. Odds of death (aOR 2.54 [95% CI 1.42 to 4.55]; P = .002), a cognitive score <85 (aOR 1.78 [95% CI 1.09 to 2.91]; P = .02), and a Gross Motor Functional Classification Scale level ≥2 (aOR 1.73 [95% CI 1.04 to 2.88]; P = .04) were significantly higher with bevacizumab therapy. CONCLUSIONS: In this multicenter cohort of preterm infants, ROP treatment modality was not associated with differences in death or NDI, but the bevacizumab group had higher mortality and poor cognitive outcomes in early childhood. These data reveal the need for a rigorous appraisal of ROP therapy.

Importance: Birth weight (BW) is an important predictor of mortality and morbidity. At extremely early gestational ages (GAs), BW may influence decisions regarding initiation of resuscitation. Objective: To characterize outcomes of liveborn infants with a BW less than 400 g. Design, Setting, and Participants: This retrospective multicenter cohort study analyzed extremely preterm infants born between January 2008 and December 2016 within the National Institute of Child Health and Human Development Neonatal Research Network. Infants with a BW less than 400 g and a GA of 22 to 26 weeks were included. Active treatment was defined as the provision of any potentially lifesaving intervention after birth. Survival was analyzed for the entire cohort; neurodevelopmental impairment (NDI) was examined for those born between January 2008 and December 2015 (birth years with outcomes available for analysis). Neurodevelopmental impairment at 18 to 26 months' corrected age (CA) was defined as a Bayley Scales of Infant and Toddler Development, Third Edition, cognitive composite score less than 85, a motor composite score less than 85, moderate or severe cerebral palsy, gross motor function classification system score of 2 or greater, bilateral blindness, and/or hearing impairment. Data were analyzed from September 2017 to October 2018. Exposures: Birth weight less than 400 g. Main Outcomes and Measures: The primary outcome was survival to discharge among infants who received active treatment. Analysis of follow-up data was limited to infants born from 2008 to 2015 to ensure children had reached assessment age. Within this cohort, neurodevelopmental outcomes were assessed for infants who survived to 18 to 26 months' CA and returned for a comprehensive visit. Results: Of the 205 included infants, 121 (59.0%) were female, 133 (64.9%) were singletons, and 178 (86.8%) were small for gestational age. Almost half (101 of 205 [49.3%]) received active treatment at birth. A total of 26 of 205 infants (12.7%; 95% CI, 8.5-18.9) overall survived to discharge, and 26 of 101 actively treated infants (25.7%; 95% CI, 17.6-35.4) survived to discharge. Within the subset of infants with a BW less than 400 g and a GA of 22 to 23 weeks, 6 of 36 actively treated infants (17%; 95% CI, 6-33) survived to discharge. Among infants born between 2008 and 2015, 23 of 90 actively treated infants (26%; 95% CI, 17-36) survived to discharge. Two infants died after discharge, and 2 were lost to follow-up. Thus, 19 of 90 actively treated infants (21%; 95% CI, 13-31) were evaluated at 18 to 26 months' CA. Moderate or severe NDI occurred in 14 of 19 infants (74%). Conclusions and Relevance: Infants born with a BW less than 400 g are at high risk of mortality and significant morbidity. Although 21% of infants survived to 18 to 26 months' CA with active treatment, NDI was common among survivors.

Background: Reported benefits of maternal nutrition supplements commenced during pregnancy in low-resource populations have typically been quite limited. Objectives: This study tested the effects on newborn size, especially length, of commencing nutrition supplements for women in low-resource populations ≥3 mo before conception (Arm 1), compared with the same supplement commenced late in the first trimester of pregnancy (Arm 2) or not at all (control Arm 3). Methods: Women First was a 3-arm individualized randomized controlled trial (RCT). The intervention was a lipid-based micronutrient supplement; a protein-energy supplement was also provided if maternal body mass index (kg/m2) was <20 or gestational weight gain was less than recommendations. Study sites were in rural locations of the Democratic Republic of the Congo (DRC), Guatemala, India, and Pakistan. The primary outcome was length-for-age z score (LAZ), with all anthropometry obtained <48 h post delivery. Because gestational ages were unavailable in DRC, outcomes were determined for all 4 sites from WHO newborn standards (non-gestational-age-adjusted, NGAA) as well as INTERGROWTH-21st fetal standards (3 sites, gestational age-adjusted, GAA). Results: A total of 7387 nonpregnant women were randomly assigned, yielding 2451 births with NGAA primary outcomes and 1465 with GAA outcomes. Mean LAZ and other outcomes did not differ between Arm 1 and Arm 2 using either NGAA or GAA. Mean LAZ (NGAA) for Arm 1 was greater than for Arm 3 (effect size: +0.19; 95% CI: 0.08, 0.30, P = 0.0008). For GAA outcomes, rates of stunting and small-for-gestational-age were lower in Arm 1 than in Arm 3 (RR: 0.69; 95% CI: 0.49, 0.98, P = 0.0361 and RR: 0.78; 95% CI: 0.70, 0.88, P < 0.001, respectively). Rates of preterm birth did not differ among arms. Conclusions: In low-resource populations, benefits on fetal growth-related birth outcomes were derived from nutrition supplements commenced before conception or late in the first trimester. This trial was registered at clinicaltrials.gov as NCT01883193.
