Occurrence of heavy metals coupled with elevated levels of essential elements in chocolates: Health risk assessment.

The presence of contaminants in cacao-derived products, especially in chocolates, has raised concerns regarding food safety and human health. The study assessed the concentration variation of 16 elements in 155 chocolate samples from the US market by cacao content and country of geographic origin. The study further examined the potential health risks posed by toxic metals and determined the contribution of essential elements to the Daily Recommended Intake (DRI), estimated based on an ounce (∼28.4 g) of daily chocolate consumption. Dark chocolates with ≥50 % cacao exhibited consecutively increasing mean levels from 1.2 to 391 µg/kg for U, Tl, Th, As, Pb, Se, Cd, and Co. Similarly, Ni, Sr, Cu, Mn, Zn, Fe, Ca, and Mg had mean concentrations from 4.0 to 1890 mg/kg. Dark chocolates sourced from Central and South America exhibited the highest mean levels of Cd, and South America samples also contained elevated Pb, whereas those from West Africa and Asia had low Cd and Pb, respectively. Cacao contents showed increasingly strong association with Cd, Co, Mn, Sr, Ni, Cu, Zn, and Mg (r = 0.60-0.84), and moderately with Se, Fe, As, and Tl (r = 0.35-0.49), indicating these elements are primarily derived from cacao beans. Weak association of cacao contents with Pb, Th, and U levels (r < 0.25), indicates post-harvest contaminations. Hazard Quotient (HQ) > 1 was found only for Cd in 4 dark chocolates, and Hazard Index (HI) > 1 for cumulative risk of Cd, Pb, Ni, As, and U was found in 33 dark chocolates, indicating potential non-carcinogenic risks for 15 kg children but none for 70 kg adults. Dark chocolate also substantially contributed to 47-95 % of the DRI of Cu for children and 50 % for adults. Dark chocolates also provided notable Fe, Mn, Mg, and Zn contributions to the DRI. These essential elements are recognized to reduce the bioavailability of toxic metals such as Cd, Pb, or Ni, thereby potentially lowering associated health risks. This study informs consumers, food industries, and regulatory agencies to target cacao origins or chocolate brands with lower toxic metal contents for food safety and minimizing adverse health effects.

Real-Time Real-World Digital Monitoring of Adolescent Suicide Risk During the Six Months Following Emergency Department Discharge: Protocol for an Intensive Longitudinal Study.

BACKGROUND: Suicide is the second leading cause of death in adolescents, and self-harm is one of the strongest predictors of death by suicide. The rates of adolescents presenting to emergency departments (EDs) for suicidal thoughts and behaviors (STBs) have increased. Still, existing follow-up after ED discharge is inadequate, leaving a high-risk period for reattempts and suicide. There is a need for innovative evaluation of imminent suicide risk factors in these patients, focusing on continuous real-time evaluations with low assessment burden and minimal reliance on patient disclosure of suicidal intent. OBJECTIVE: This study examines prospective longitudinal associations between observed real-time mobile passive sensing, including communication and activity patterns, and clinical and self-reported assessments of STB over 6 months. METHODS: This study will include 90 adolescents recruited on their first outpatient clinic visit following their discharge from the ED due to a recent STB. Participants will complete brief weekly assessments and be monitored continuously for their mobile app usage, including mobility, activity, and communication patterns, over 6 months using the iFeel research app. Participants will complete 4 in-person visits for clinical assessment at baseline and at the 1-, 3-, and 6-month follow-ups. The digital data will be processed, involving feature extraction, scaling, selection, and dimensionality reduction. Passive monitoring data will be analyzed using both classical machine learning models and deep learning models to identify proximal associations between real-time observed communication, activity patterns, and STB. The data will be split into a training and validation data set, and predictions will be matched against the clinical evaluations and self-reported STB events (ie, labels). To use both labeled and unlabeled digital data (ie, passively collected), we will use semisupervised methods in conjunction with a novel method that is based on anomaly detection notions. RESULTS: Participant recruitment and follow-up started in February 2021 and are expected to be completed by 2024. We expect to find prospective proximal associations between mobile sensor communication, activity data, and STB outcomes. We will test predictive models for suicidal behaviors among high-risk adolescents. CONCLUSIONS: Developing digital markers of STB in a real-world sample of high-risk adolescents presenting to ED can inform different interventions and provide an objective means to assess the risk of suicidal behaviors. The results of this study will be the first step toward large-scale validation that may lead to suicide risk measures that aid psychiatric follow-up, decision-making, and targeted treatments. This novel assessment could facilitate timely identification and intervention to save young people's lives. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/46464.

Abnormal Uterine Bleeding Among COVID-19 Vaccinated and Recovered Women: a National Survey.

The objective of this research was to characterize menstrual changes including amount, duration, and frequency among COVID-19 vaccinated and infected women. We conducted an online nationwide questionnaire survey on premenopausal, non-pregnant women over 18 years of age in Israel, querying about any changes in their menstrual patterns after COVID-19 vaccination or infection. In total, 10,319 women responded, of which 7904 met the inclusion criteria. Changes in menstrual patterns following COVID-19 vaccination or infection were reported in 3689/7476 (49.3%) women compared with 202/428 (47.2%) women, respectively, (P = .387). The most commonly described menstrual disturbance was excessive bleeding (heavy, prolonged, or intermenstrual) in both the vaccinated and infected groups, (80.6% versus 81.4%, respectively, P = .720). Among women who experienced abnormal uterine bleeding (AUB), in most cases (61.1%), it occurred between the vaccination and the ensuing menstrual period. Menstrual disturbances were similar in type among the vaccinated and infected women. In conclusion, AUB emerged as a side effect of the BNT162b2 vaccine and a symptom of the COVID-19 infection and was characterized mainly by excessive bleeding. Although the precise incidence could not be determined in this study, the type of bleeding disorder as well as the characterization of risk factors including increasing age and a baseline menstrual pattern of prolonged, frequent, and heavy menses are well defined. The incidence and the long-term consequences of the BNT162b2 vaccine on uterine bleeding warrant further investigation.

Does obesity change the perception of pelvic organ prolapse?

INTRODUCTION AND HYPOTHESIS: There is a complex relationship between obesity and pelvic organ prolapse. The objective of our study was to evaluate whether body mass index (BMI) changes the relationship between signs and symptoms of prolapse. METHODS: This was a retrospective observational study based on datasets of women seen in a tertiary urogynecological center with symptoms of pelvic floor and lower urinary tract dysfunction between April 2012 and October 2015. Patients underwent a structured interview, clinical examination (based on the POP-Q) and 4D transperineal ultrasound (TPUS). Offline assessment of sonographic organ descent was undertaken later, blinded to all patient data. RESULTS: Weight and BMI affect the relationship between symptoms and signs of prolapse. This effect is statistically highly significant. The more obese a patient is, the less likely she is to notice a given degree of objective prolapse, regardless of whether it is diagnosed clinically or on imaging. CONCLUSIONS: In this retrospective study, we found a highly significant effect of weight and BMI on prolapse perception in the sense that obesity seems to mask prolapse while a low BMI increases the likelihood of a given degree of prolapse being noticed by the patient.

Pelvic organ prolapse in nulliparae.

BACKGROUND: Pregnancy and childbirth are thought to be the strongest environmental risk factors for pelvic organ prolapse, but prolapse does occur in nulliparae. AIM: To characterise prolapse in vaginal nulliparae. MATERIAL AND METHODS: This was a retrospective study using archived clinical and imaging data of 368 vaginally nulliparous women seen between 2006 and 2017 at two tertiary urogynaecological centres. Patients underwent a standardised interview, clinical examination and 3D/4D translabial ultrasound. Volume datasets were analysed by the second author, blinded against all clinical data, using post-processing software on a personal computer. Significant prolapse was defined as Pelvic Organ Prolapse Quantification system stage ≥2 for the anterior and posterior compartment, and stage ≥1 for the central compartment. On imaging, significant prolapse was defined as previously described. RESULTS: Of 4297 women seen during the inclusion period, 409 were vaginally nulliparous, for whom 368 volume data sets could be retrieved. Mean age was 50 years (17-89) and mean body mass index 29 (16-64). Eighty-one (22%) presented with prolapse symptoms. On clinical examination, 106 women (29%) had significant prolapse, mostly of the posterior compartment (n = 70, 19%). On imaging 64 women showed evidence of significant prolapse (17%), again mostly posterior (n = 47, 13%). Rectovaginal septal defects were even more common in 69 (19%). On multivariate analysis we found no differences between true nulliparae (n = 184) and women delivered exclusively by caesarean section (n = 184). CONCLUSIONS: Prolapse occurs in vaginal nulliparae, but it has distinct characteristics. Rectocele predominates, while cystocele and uterine prolapse are uncommon. Pregnancy and caesarean delivery seem to have little effect.

Minimally invasive meshless and minimal dissection ligament fixation system for apical organ prolapse procedures: A 4-year prospective follow up study.

OBJECTIVE: EnPlace™ (formerly named NeuGuide™) is a minimally invasive meshless anchoring system for pelvic organ prolapse (POP) repair designed to provide centro-apical pelvic floor support. We present a 4-year prospective follow up evaluation of this repair system. METHODS: This was a single-center longitudinal prospective study of women with advanced POP who underwent pelvic floor apical repair using EnPlace™ with at least 4 years of follow-up. The primary outcome was surgical success defined as anatomical success, no symptoms of vaginal bulging and no need for re-treatment. A standardized validated questionnaire to assess symptom burden was used. RESULTS: Fifteen women were enrolled in the study. Two patients were lost to follow-up. The median follow-up was 51 months (range 42-57) with a surgical success rate of 92.3%. One patient (7.7%) reported symptoms of vaginal vault prolapse and underwent a repeated prolapse surgery. Using the UDI-6 questionnaire, an improvement in all domains was seen. CONCLUSION: The 4-year prospective follow up suggests that apical repair using the EnPlace™ device may be considered safe and effective for sacrospinous ligament fixation with a sustainable long-term success. This procedure is a minimally invasive meshless addition to pelvic surgeon's armamentarium.

Is perineal hypermobility an independent predictor of obstructive defecation?

INTRODUCTION AND HYPOTHESIS: Symptoms of obstructed defecation (OD) and anatomical abnormalities of the posterior compartment are prevalent in urogynecological patients. The aim of this study was to determine whether perineal hypermobility is an independent predictor of OD, as is the case for rectocele, enterocele and rectal intussusception. METHODS: This is a retrospective study of 2447 women attending a tertiary urodynamic center between September 2011 and December 2016. The assessment included a structured interview, urodynamic testing, a clinical examination and 4D transperineal ultrasound. After exclusion of previous pelvic floor surgery and defined anatomical abnormalities of the anorectum, 796 patients were left for analysis. Perineal hypermobility was defined as rectal descent ≥ 15 mm below the symphysis pubis, determined in stored ultrasound volume datasets offline, using proprietary software, blinded to all other data. Any association between perineal hypermobility and symptoms of obstructed defecation was tested for by chi-square (X2) test. RESULTS: For the 796 patients analyzed, median age was 52 (range, 16-88) years with a mean BMI of 27 (range, 15-64) kg/m2. Average vaginal parity was two (range, 0-8). Reported OD symptoms in this group included sensation of incomplete emptying in 335 (42%), straining at stool in 300 (37%) and digitation in 83 (10%). At least one of those symptoms was reported by 424 (53%) women; 153 showed perineal hypermobility. There was no significant association between perineal hypermobility and OD symptoms on univariate testing. CONCLUSIONS: We found no evidence of an independent association between perineal hypermobility and obstructed defecation.

Does Vaginal Parity Alter the Association Between Symptoms and Signs of Pelvic Organ Prolapse?

OBJECTIVES: This study aimed to investigate whether the number of vaginal births a woman has alters the association between symptoms and signs of pelvic organ prolapse. METHODS: In this retrospective study, we investigated data on 1748 women seen between April 2012 and January 2016. To elucidate whether the number of vaginal births is a confounder of this relationship, we used receiver operating characteristic statistics to investigate the association between symptoms and signs of prolapse in women of different vaginal parity. RESULTS: A higher number of vaginal births was associated with a higher likelihood of symptoms of prolapse for any given degree of prolapse. Multivariate modeling, however, showed this confounding effect to be due to higher vaginal parity in older women (P < .001). Receiver operating characteristic curves obtained for the association between symptoms and signs of prolapse were near identical regardless of whether vaginal parity was included in the modeling. This was true for both clinical and imaging assessments of prolapse. CONCLUSIONS: Although vaginal childbirth is associated with symptoms of prolapse, the number of vaginal births does not alter the relationship between symptoms and signs of prolapse among individuals presenting to a tertiary care center for evaluation. Previously published limits for "normal" pelvic organ mobility can be used irrespective of vaginal parity.

The association between vacuum-assisted vaginal delivery and anal sphincter injury.

INTRODUCTION: Vacuum-assisted vaginal delivery (VAVD) is considered a major risk factor for obstetric anal sphincter injuries (OASIS). However, it is difficult to estimate its true contribution to the occurrence of OASIS, as its performance may be confounded by other determinants. Therefore, we aimed to evaluate the association of VAVD with OASIS among primiparous women compared to SVD. METHODS: A retrospective cohort study including all primiparous women who vaginally delivered a cephalic singleton gestation during the years 2011 to 2020. As VAVDs were not performed before 34 gestational weeks, we capped the cohort at this gestational age. Women were allocated into two groups: VAVDs and spontaneous vaginal deliveries (SVD). We compared women with OASIS to those without and performed a multivariate analysis including factors that were found significant in the univariate analysis. We further divided the whole cohort into different subcategories. The primary outcome was the rate of OASIS in VAVD compared to SVD. RESULTS: Overall, 23,272 primiparous vaginal deliveries were available for evaluation. Of these, 3595 delivered by VAVD and 19,677 delivered spontaneously. OASIS occurred in 421 (1.8%) of the deliveries. OASIS were more common in VAVDs than in SVDs [83 (2.3%) vs. 338 (1.7%), respectively, OR (95% CI) 1.35 (1.06-1.72), p = 0.01]. After multivariate regression analysis, OASIS were not found to be independently associated with the mode of delivery [aOR 1.21 (95% CI) 0.88-1.68, P = 0.23]. In a categorical analysis of OASIS rates by risk factors and mode of delivery, VAVD was not associated with an increase in OASIS among women giving birth to neonates weighing > 3500 g compared to SVD [OR (95% CI) 1.02 (0.65-1.62), P = 0.90]. CONCLUSION: Among primiparous women VAVD did not increase the risk of OASIS compared to SVD.

Validation of the Wexner scale in a Hebrew-speaking population.

INTRODUCTION: The Cleveland Clinic Incontinence Score, known as the Wexner Score (WS), is a simple, disease-specific questionnaire for anal incontinence (AI) assessment. We aimed to translate and validate a Hebrew version of the WS. METHODS: Between November 2018 and December 2019, the WS was back translated and reviewed by a multidisciplinary pelvic floor team. The questionnaire was filled out by patients visiting the urogynecology and surgical pelvic floor clinics. Two weeks after completion, the patients were contacted using telephone surveys to assess the test-retest reliability examination. Construct validity was assessed by comparing the WS to the Colorectal-Anal Distress Inventory 8 (CRADI-8), a part of the validated Hebrew version of the Pelvic Floor Distress Inventory questionnaire (PFDI-20). RESULTS: Overall, 91 female patients completed the WS questionnaire. Eighty-five percent (n = 78) responded to the re-test WS questionnaire. A high intraclass coefficient of 0.87 was found in the WS total score, with a range from 0.82 to 0.86 for its subscales. A significant positive relationship between the Hebrew versions of the WS and CRADI-8 scores was established (r = 0.66, p < 0.0001). CONCLUSION: A new, Hebrew-translated version of the WS is a reliable and valid instrument for assessing AI.

Parity and anal sphincter trauma.

INTRODUCTION AND HYPOTHESIS: Obstetric anal sphincter injury (OASI) is a form of maternal trauma secondary to vaginal birth. Women with a history of OASI are deemed to be at a higher risk of recurrence. However, it is unclear if multiparity is associated with higher prevalence. The aim of the study was to test the following hypothesis: the prevalence of external anal sphincter (EAS) tears diagnosed on transperineal ultrasound (TPUS) is related to vaginal parity. METHODS: A retrospective observational study on 1,273 women who attended a tertiary urogynecology service between January 2014 and December 2016. Patients had undergone a standardized interview, clinical examination and 4D TPUS. Tomographic ultrasound imaging was used to evaluate the EAS, blinded to all clinical data. RESULTS: Of 1,273 women, 1,143 (90%) were vaginally parous, with a mean vaginal parity of 2 (range 1-8). Mean age was 54 (range 17-89) years. Anal incontinence was reported in 186 women (15%) with an average St Mark's incontinence score of 12 (range 1-23). EAS defects on ultrasound were identified in 148 (12%). On univariate analysis, there was no significant difference in the prevalence of EAS defects in vaginally primiparous and multiparous women (p = 0.460). CONCLUSIONS: There is no significant difference in the prevalence of EAS tears between vaginally primiparous and multiparous women. This argues against additional traumatic effects of subsequent vaginal births.

Birthweight and pelvic floor trauma after vaginal childbirth.

INTRODUCTION AND HYPOTHESIS: Birthweight seems to be a risk factor for levator ani muscle (LAM) avulsion and a predictive factor for pelvic organ prolapse (POP). Most trauma seems due to first vaginal birth. METHODS: One thousand one hundred twenty-five women with at least two vaginal deliveries underwent a physician-directed interview, followed by clinical examination (digital palpation and Pelvic Organ Prolapse Quantification-POPQ) and 4D translabial ultrasound. Ultrasound volume data were obtained at rest, on pelvic floor contraction and Valsalva. The investigator, blinded to all other data, performed offline analysis of the LAM integrity and hiatal area on Valsalva. We tested for associations between birthweight of the first and of the largest vaginally born baby on the one hand and avulsion and symptoms/signs of prolapse on the other hand. RESULTS: Between July 2014 and July 2017, 1575 patients were seen. After exclusion of nulliparae and women with just one vaginal birth, 1202 remained. Another 77 were excluded due to missing data, leaving 1125. A significant association was found between birthweight and LAM avulsion as well as significant prolapse on POPQ. The birthweight of the first vaginally born baby was at least as predictive for avulsion as the birthweight of any subsequent births, even when adjusted for maternal age at first delivery and use of forceps. CONCLUSIONS: The birthweight of the first vaginally born baby is associated with levator avulsion and subsequent POP. Maximum weight of vaginal births does not seem to be a stronger predictor.

Delivery mode and the risk of levator muscle avulsion: a meta-analysis.

INTRODUCTION AND HYPOTHESIS: Female pelvic organ prolapse (POP) is a common condition, with a lifetime risk for surgery of 10-20%. Pregnancy and childbirth are the commonest modifiable risk factors for POP, and avulsion of the levator ani muscle is likely to be an etiological factor. Avulsion is more common in instrumental delivery. However, we were unable to identify a meta-analysis on this issue. Our aim was to perform a systemic review and quantitative meta-analysis of the prevalence of avulsion relative to delivery mode. METHODS: Four electronic databases (MEDLINE, PubMed, Embase, and Google Scholar) were searched for studies published between 1991 and 1 October 2018 without language restrictions. RESULTS: Twenty studies met inclusion criteria, and 14 were prospective. Seventeen used sonographic techniques; three were magnetic resonance (MR) studies. For this review, three comparisons were performed: forceps vs. vacuum (9 studies), forceps vs. normal vaginal delivery (NVD) (12 studies), and vacuum vs. NVD (12 studies). The first meta-analysis showed an increased risk for avulsion following forceps compared with vacuum, with an odds ratio (OR) of 4.57 and confidence interval (CI) 3.21-6.51, p < 0.001. The second showed an increased risk for avulsion following forceps compared with NVD, with an OR of 6.94 (4.93-9.78), p < 0.001. The third showed no significant increased risk for avulsion following vacuum compared with NVD, with an OR of 1.31 (1.00-1.72), p = 0.051. CONCLUSIONS: Forceps is a strong risk factor for avulsion, with an OR of 6.94 (4.93-9.78) compared with NVD and an OR of 4.57 (3.21-6.51) compared with vacuum birth.

Does Patient Posture Affect the Ultrasound Evaluation of Pelvic Organ Prolapse?

OBJECTIVES: Translabial ultrasound (US) imaging is an emerging method for the evaluation of pelvic organ prolapse (POP). Normative data to date are limited to imaging in the supine position. The purpose of this study was to evaluate the effect of posture changes on US pelvic organ mobility. METHODS: This work was a retrospective study of 175 women seen in a tertiary urogynecologic center for symptoms of lower urinary tract and pelvic floor dysfunction. All underwent a standardized interview, POP quantification prolapse assessment, and 4-dimensional translabial US examination in supine and standing positions. Offline measurement of organ descent on the Valsalva maneuver was undertaken at a later date and was blinded against all other data. RESULTS: The mean age was 58 (SD, 13.5; range, 17 to 89) years, with a mean body mass index of 29 (SD, 6.1; range, 18 to 53) kg/m2 . In total, 58.9% (n = 103) presented with symptoms of prolapse. Clinically, 82.8% (n = 145) had substantial prolapse on the POP quantification assessment. On imaging, bladder, uterine, and rectal ampulla positions were significantly lower, and the hiatal area on the Valsalva maneuver was larger in the standing position (P < .03). On receiver operating characteristic statistics assessing correlations between POP symptoms and US pelvic organ descent, the area under the curve was higher in the standing position, but the difference was not statistically significant. CONCLUSIONS: Measurements of organ descent and hiatal dimensions are generally higher in the standing position. However, they are not reflected in a stronger association between symptoms and organ descent. Hence, imaging in the standing position can be limited to those patients in whom a false-negative assessment result is suspected.

Should Genital Hiatus/Perineal Body Be Measured at Rest or on Valsalva?

OBJECTIVE: Genital hiatus (Gh) and perineal body (Pb) are part of the Pelvic Organ Prolapse Quantification assessment system, but it is unclear whether measurements should be taken at rest or on Valsalva. This study was designed to assess the predictive value of Gh and Pb measurements obtained at rest and on Valsalva for signs and symptoms of pelvic organ prolapse (POP). METHODS: This is a retrospective study involving 416 women who presented to a tertiary urogynecology unit with symptoms of pelvic floor dysfunction. Genital hiatus and Pb were measured at rest and on maximal Valsalva. The strength of association between binary markers of POP and measurements of Gh/Pb was estimated using logistic regression analysis. Receiver operator characteristic statistics were used to compare predictive values of Gh and Pb measurements obtained at rest and on Valsalva. RESULTS: A total of 451 women were seen during the study period. Thirty-five were excluded owing to missing data, leaving 416. Fifty-four percent (n = 223) complained of POP symptoms. On examination, 80% (n = 332) had significant POP (stage 2+ in anterior or posterior compartments or stage 1+ in the central compartment). On imaging, significant POP was diagnosed in 66% (n = 275). Mean hiatal area was 22 cm (SD, 7; range, 5-49 cm) at rest and 30 cm (SD, 10; range, 11-69 cm) on Valsalva. Genital hiatus and Pb measured on Valsalva were consistently stronger predictors of prolapse symptoms and objective prolapse (by clinician examination and by ultrasound) than at Gh and Pb measured at rest. The corresponding area under the curve values were significantly larger for Gh/Pb measures on Valsalva after adjusting for multiple confounders. CONCLUSIONS: Genital hiatus/Pb measured on maximal Valsalva is a superior predictor of symptoms and signs of POP compared with Gh/Pb at rest.

Impact of subsequent pregnancies on pelvic floor functional anatomy.

INTRODUCTION AND HYPOTHESIS: Vaginal childbirth clearly has an effect on pelvic floor anatomy, and pregnancy itself also likely plays a role. This study investigated the effects of consecutive pregnancies by comparing pelvic organ support and function in urogynecological patients delivered by cesarean section (CS) only. METHODS: This was a retrospective study using 161 archived data sets of urogynecological patients delivered exclusively by CS presenting with symptoms of pelvic floor dysfunction between 2007 and 2015. Patients had undergone an interview, clinical examination using the Pelvic Organ Prolapse Quantification (POP-Q) system, and 3D/4D translabial ultrasound (TLUS) using Voluson systems. Measures of functional pelvic floor anatomy were obtained from stored ultrasound (US) volumes at a later date, using proprietary software, and blinded against all other data. RESULTS: One hundred and sixty-one women delivered exclusively by CS were seen in a urogynecological clinic. Volume data analysis was possible in 151 patients. Mean age was 52 (26-82) years, with a mean body mass index (BMI) of 29.5 (18.4-48.7) kg/m2. Forty-three (28.5%) women had one CS, 67 (44.4%) had two, and 41 (27.1%) had three or more. On multivariate analysis, adjusting for age, BMI, history of hysterectomy, and incontinence or prolapse surgery, there were no significant differences between groups. CONCLUSIONS: On comparing women with one, two, or three or more CS, we found no significant differences in any measured sonographic parameters of pelvic organ descent and pelvic floor muscle function. This implies that subsequent pregnancies after the first are unlikely to exert significant additional effects on pelvic floor functional anatomy.

Prolapse assessment supine and standing: do we need different cutoffs for "significant prolapse"?

INTRODUCTION AND HYPOTHESIS: Translabial ultrasound (TLUS) has shown good correlations between clinical examination and imaging findings in the supine position, and limits of normality have been described. This is not the case for imaging in the standing position. This study was designed to test the hypothesis that different cutoff values are required for imaging in the standing position. METHODS: This was a retrospective study carried out in a tertiary urogynecological unit in women presenting with symptoms of lower urinary tract and pelvic floor dysfunction between August 2013 and December 2015. All women underwent a standardized interview, 4D TLUS and a POP-Q assessment. Organ descent on ultrasound was measured relative to the postero-inferior margin of the symphysis pubis (SP) on maximal Valsalva in the supine and standing positions. Receiver operator characteristic (ROC) statistics were used to determine optimal cutoffs for "normal" pelvic organ support. RESULTS: We assessed 243 data sets. Mean patient age was 57 years. Prolapse symptoms were reported by 59.2%, and POP of stage ≥ 2 was found in 82.3%. On analysing imaging data sets obtained in the standing position, we obtained similar cutoff values to those established previously for supine imaging, using ROC statistics. The levator hiatus distended significantly more on Valsalva in the standing position compared with supine, and on ROC analysis we identified a new optimal cutoff of 29 cm2. CONCLUSIONS: Established cutoffs for supine imaging of organ descent are suitable for imaging in the standing position. Hiatal distensibility may require a higher cutoff of 29 cm2.

Risk factors for prolapse recurrence: systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: Female pelvic organ prolapse (POP) is a common condition, with a lifetime risk for surgery of 10-20%. Prolapse procedures are known to have a high reoperation rate. It is assumed that etiological factors for POP may also be risk factors for POP recurrence after surgery. There are few reviews available evaluating risk factors for prolapse and recurrence or recently updated meta-analysis on this topic. Our aim was to perform a systematic review and quantitative meta-analysis to determine risk factors for prolapse recurrence after reconstructive surgery. METHODS: Four electronic databases (MEDLINE, PubMed, EMBASE, and Google Scholar) were searched between 1995 and 1 January 2017, with no language restrictions. RESULTS: Twenty-five studies met inclusion criteria for a total of 5082 patients with an average recurrence rate of 36%. Variables on which a meta-analysis could be performed were body mass index (BMI) (n = 12), age (n = 11), preoperative stage (n = 9), levator avulsion (n = 8), parity (n = 8), constipation/straining (n = 6), number of compartments involved (n = 4), prior hysterectomy (n = 4), familiy history (n = 3), and several other predictors evaluated in only three studies. The following meta- analyses identified significant predictors: levator avulsion [odds ratio (OR) 2.76, P < 0.01], preoperative stage 3-4 (OR 2.11, P < 0.001), family history (OR 1.84, P = 0.006), and hiatal area (OR 1.06/cm2, P = 0.003). CONCLUSIONS: Levator avulsion, prolapse stage, and family history are significant risk factors for prolapse recurrence.

Correlations between Sonographic and Urodynamic Findings after Mid Urethral Sling Surgery.

PURPOSE: We studied correlations between sonographic and urodynamic findings after suburethral sling surgery. MATERIALS AND METHODS: This retrospective study was done in 141 women who underwent multichannel urodynamic testing and translabial 4-dimensional ultrasound after suburethral sling surgery between 2006 and 2016. We determined the sling-pubis gap, ie the distance between the sling and the inferior posterior margin of the pubic symphysis, during the Valsalva maneuver and the urethral motion profile. The latter was assessed by calculating the mobility vectors of 6 equidistant points along the length of the urethra from the bladder neck to the external urethral meatus against the dorsocaudal margin of the pubic symphysis during the Valsalva maneuver. Correlations were determined between the sling-pubis gap and the mobility vectors, and between these measures and urodynamic data. RESULTS: Median followup in the 126 women with complete data was 36 months. Significant correlations were found between the sling-pubis gap and the mid urethral mobility vectors (all p <0.02). The sling-pubis gap and the mid urethral mobility vectors negatively correlated with detrusor pressure at maximum flow (p = 0.037 and 0.004, respectively). Urodynamic stress incontinence was more likely in women with a greater sling-pubis gap (p = 0.003). CONCLUSIONS: The tighter the sling on ultrasound, the less likely is urodynamic stress incontinence and the higher the detrusor pressure during voiding.

Digitation to Void: What Is the Significance of This Symptom?

OBJECTIVE: Digitation to void is defined as the need to apply manual pressure on the perineum or the vagina to assist with voiding. It has been associated with prolapse; however, there is little objective data concerning this symptom. Our aim was to determine the correlation between digitation to void, symptoms and signs of pelvic organ prolapse (POP), and urodynamic data. METHODS: This was a retrospective study that included a total of 1174 patients seen at a tertiary urogynecological unit. A standardized history was obtained from all patients followed by multichannel urodynamic testing, Pelvic Organ Prolapse Quantification scoring and 3-D/4-D translabial ultrasound. Stored 4-D translabial ultrasound volumes were obtained and analyzed at a later date. RESULTS: Digitation to void was present in 7% (n = 83) of our population. It is associated with primary symptoms of POP (odds ratio [OR], 25.75; confidence interval [CI], 8.08-82.05), clinically significant POP (OR, 5.62; CI, 2.25-14.02), and POP on ultrasound (OR, 5.39; CI, 2.67-10.88). Cystocele presented the strongest association, clinically (OR, 3.45; CI, 1.98-6.03) and on ultrasound (OR, 4.04; CI, 2.46-6.64). Digitation to void was also associated with symptoms of voiding dysfunction (OR, 6.38 [3.83-10.64]) and slower maximum urine flow rate centile (18.4 vs 24.9, P = 0.017). CONCLUSIONS: Digitation to void is strongly associated with primary symptoms of prolapse and of voiding dysfunction, clinically significant POP, and pelvic organ descent on ultrasound. It is also associated with objective voiding dysfunction. The strongest associations were found with cystocele, both clinically and on imaging.
