The female pelvic floor through midlife and aging

At What Point in the Menstrual Cycle Are the Pelvic Floor Muscles at Their Weakest?

Pelvic floor muscle (PFM) strength is a critical factor for optimal pelvic floor function. Fluctuations in strength values based on different phases of the menstrual cycle (MC) could signify a need for a paradigm shift in evaluating, approaching, and planning training. This research aims to examine and contrast the pelvic floor muscle strength during different phases of the menstrual cycle. A prospective observational study employing digital assessment with the modified Oxford scale and vaginal dynamometry measurements was performed, in order to assess the baseline strength and the contraction strength of the PFMs in eumenorrheic females at three different phases of the MC: the early follicular phase (EFP), the late follicular phase (LFP), and the mid-luteal phase (MLP). During two complete cycles, tympanic temperature and body weight were measured and the urinary luteinizing hormone concentration was tested to determine the time of ovulation. In total, 216 dynamometric measurements of PFM strength were obtained from eighteen nulliparous women (25.72 ± 5.03 years). There were no differences between the baseline strength (p = 0.886) and the contraction strength (p = 0.756) with the dynamometric speculum. In the post hoc analysis, the baseline strength, contraction strength, and strength showed no significant differences between MC phases. As no differences in PFM strength in women were found, the PFMs do not seem to be weaker at any time during the menstrual cycle. It appears that the assessment, establishment, and monitoring of a PFM training program could be initiated at any point in the cycle.

Pelvic Pain of Myofascial Origin in Women: Correlation with Lower Urinary Tract Symptoms

Introduction

Women with lower urinary tract symptoms (LUTS) and high-tone pelvic floor often experience pain and have positive trigger points upon pelvic floor examination. However, the correlation of these findings has not yet been systematically examined and sufficiently understood. The aim of this cross-sectional study is to examine the correlation of pelvic myofascial pain with LUTS and pelvic floor tone.

Materials and Methods

All participants filled a standardized pelvic floor questionnaire to assess LUTS, which consists of a total of 43 questions regarding bladder, bowel, and sexual function as well as prolapse symptoms. Myofascial trigger points in different muscle groups including pubococcygeus, iliococcygeus, and obturator as well as pelvic floor muscle tone were assessed using a standardized digital examination technique.

Results

110 women were included in the study. There was a significant correlation between pain in various muscle groups and LUTS as well as high-tone pelvic floor muscle. A significant correlation could also be found between high pelvic floor muscle tone and the overall questionnaire score (p < 0.001) as well as the bladder function score (p < 0.001) and various pain scores of the different groups. Individuals with high-tone pelvic floor were more likely to have more LUTS and higher pain scores.

Conclusions

The existence of myofascial pelvic floor trigger points and high pelvic floor muscle tone seem to be reflective of pelvic floor symptoms, as assessed with a standardized pelvic floor questionnaire.

Flat Magnetic Stimulation for Urge Urinary Incontinence

Background and Objectives: Strategies for overactive bladder syndrome (OAB) management involve, among others, strengthening the bladder outlet to suppress urgency and neuromodulating the sacral roots. Magnetic stimulation (MS) is a technology that involves an extracorporeal device that is able to provide an electromagnetic field specifically designed to interact with pelvic floor neuromuscular tissue. The resulting tissue electrical activity induces contraction of the pelvic muscle and neuromodulation of the S2-S4 sacral roots. Flat Magnetic Stimulation (FMS) is a relevant advancement involving homogeneous electromagnetic fields, which are able to optimize the effect on the entire pelvic area. However, the benefits of this new technology for OAB syndrome are poorly known. Consequently, the aim of our study is to analyze the outcomes and quality of life (QoL) impact of FMS with Dr. Arnold (DEKA, Calenzano, Italy) in women suffering from OAB syndrome associated with urinary incontinence. Materials and Methods: This prospective study included patients with OAB, urge urinary incontinence, and no ongoing OAB treatments. At baseline (T0), the Incontinence Impact Questionnaire (IIQ-7), the Female Sexual Function Index (FSFI-19), and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) were collected. Patients underwent 8 FMS sessions of 25 min each in one month. At the termination of the therapy (T1), women repeated the ICIQ-UI SF, FSFI-19, and IIQ-7 tools. Moreover, the Patient Global Impression of Improvement (PGI-I) questionnaire was collected to evaluate the cure rate. Results: Our study enrolled a total of 57 consecutive patients. Most women had at least one second- or third-line treatment before FMS, while the remaining naive patients had contraindications to pharmacological treatments. No women reported adverse effects during the treatment. After the treatment, we observed a decrease in the IIQ-7 (p < 0.001) and ICIQ-UI SF scores (p < 0.001) and an improvement in sexual function (p < 0.001) evaluated with FSFI-19. According to PGI-I scores, 42 (73.7%) women referred to some kind of improvement, scoring ≤ 3 points. Specifically, 8.7% of patients considered themselves very much improved, 29.8% much improved, 35.1% minimally improved, and 26.3% found no changes. FMS was effective in treating OAB symptoms without any adverse effects. The mechanism is supposed to be related to suppressing the initiation of micturition. This makes FMS a promising device for treating naive and refractory urge urinary incontinence. Conclusions: The new FMS represents a promising non-pharmacological option for the treatment of naive and refractory OAB.

What are the cut-off points for vaginal manometry to differentiate women with a weak from those with a strong pelvic floor muscle contraction?: Vaginal manometry to classify a pelvic floor muscle contraction

BACKGROUND

Vaginal manometry is regarded as an objective method to assess pelvic floor muscles (PFM) function and can measure several variables during contraction.

OBJECTIVE

To determine which variables could differentiate women with/without a weak/strong PFM contraction and determine their cut-off points.

METHODS

This is a diagnostic accuracy study performed on 156 women with a mean age of 40.4 (SD, 15.9) years. The reference test was vaginal palpation and the index test was vaginal manometry (Peritron™ manometer). Variables were pressure at rest, pressure achieved with maximal voluntary contraction (MVC), MVC average, duration, gradient, and area under the curve (AUCm). The Receiver Operating Curve (AUC/ROC) and logistic regression were used to analyze the data and obtain cut-off points.

RESULTS

Excellent ability to discriminate women with a weak/strong PFM contraction was found for MVC average (cut-off: 28.93 cmH2O), MVC (cut-off: 38.61 cmH2O), and the AUCm (cut-off: 1011.93 cm²*s). The gradient variable had good discrimination ability (AUC/ROC=0.81; cut-off: 28.68 cmH2O/s). The MVC average assessed by manometry, menopausal status, and the presence of stress urinary incontinence (SUI) were associated with a weak/strong PFM contraction in the multivariate analysis; however, the most parsimonious model to discriminate weak/strong PFM contraction included only the MVC average (AUC/ROC = 0.95; sensitivity: 0.87; specificity: 0.91).

CONCLUSION

These results suggest which manometry variables are appropriate to assess and classify PFM function in females. These could be used to help physical therapists to make clinic decisions about the management of female PFM.

Effect of pregnancy and childbirth on perineal musculature in women with obesity. A longitudinal cohort study

OBJECTIVE

Evaluating the changes of the perineal muscles in primigravid women with obesity (BMI ≥ 30) and to compare the progress with primigravid women in normal BMI range.

METHODS

A prospective longitudinal cohort study was carried out. The pregnant women were studied at three moments: at 12 weeks' gestation, at 34 weeks' gestation and at 12 weeks after delivery. During the ckeck-up, perinometric measurements were taken to determine basal tone (BT), maximum contractile force (FMax) and applied forced (AF). In addition, the Oxford test (MOS) was used. General statistical mixed models were used for the statistical study.

RESULTS

Fifty nulliparous pregnant women (25 with BMI ≥ 30 and 25 with BMI < 25) were recruited at the beginning of the study and 39 completed the entire study. Basal tone (BT) was 4.62 ± 0.24 Nw at the beginning of pregnancy and decreased to 4.18 ± 0.26 Nw after delivery. Contractile capacity was 5.56 ± 0.79 Nw at week 12 and increased to 6.34 ± 1.24 Nw after delivery. When comparing the FCMax at week 12 in obese VS normal weight pregnant women, values of 5.51 ± 87 Nw vs. 5.61 ± 0.71 Nw were observed (p = 0.941). Postpartum values were 6.72 ± 1.17 Nw vs 5.95 ± 1.21 Nw (p = 0.024), higher in the obese population.

CONCLUSIONS

There is an increase in contractile strength (Fmax) at 12 weeks postpartum in order to counteract the significant decrease in basal tone (BT). The body has compensatory mechanisms that allow recovery after 3 months postpartum, with greater muscle strength in obese patients.

Menopause and stress urinary incontinence: The risk factors of stress urinary incontinence in perimenopausal and postmenopausal women

OBJECTIVE

The prevalence of stress urinary incontinence (SUI) increases around menopause. The quality of life of perimenopausal and postmenopausal women with SUI is significantly affected. This study aimed to investigate the prevalence of SUI and the associated risk factors in a population of Chinese perimenopausal and postmenopausal women.

METHODS

A total of 273 perimenopausal and postmenopausal women were enrolled, and a cross-sectional study was conducted. SUI was defined as an involuntary loss of urine with increases in abdominal pressure. Data including personal characteristics, menopause information, estrogen levels, and pelvic floor muscle strength levels were statistically analyzed.

RESULTS

The study enrolled 158 (57.9%) perimenopausal and 115 (42.1%) postmenopausal women. Sixty-six (41.8%) perimenopausal women and 56 (48.7%) postmenopausal women complained of SUI. The mean age was 49.42 ± 5.58 years. Body mass index over 24 kg/m2 (odds ratio [OR] 2.02, 95% confidence interval [CI] 1.07-3.81), vaginal delivery (OR 2.47, 95% CI 1.33-4.58), and diabetes (OR 4.65, 95% CI 1.23-17.62) were high-risk factors for SUI. Climacteric symptoms (evaluated by Kupperman index scores) were statistically related to SUI, and among the 13 symptoms, insomnia, nervousness, weakness and fatigue, arthralgia and myalgia, headache, palpitation, and sexual complaints were all correlated with SUI in perimenopausal and postmenopausal women.

CONCLUSIONS

Several factors are associated with SUI in Chinese perimenopausal and postmenopausal women. Obesity, vaginal delivery, climacteric symptoms, and diabetes were identified as the most notable risk factors. The management strategy could focus on the prevention and management of risk factors.

Pelvic floor dysfunction and electrophysiology in postpartum women at 6-8 weeks

Objective: To investigate the incidence of pelvic floor dysfunction (PFD) and electrophysiological indicators in postpartum women at 6-8 weeks and explore the influence of demographic characteristics and obstetric factors. Methods: A survey questionnaire collected information about the conditions of women during their pregnancy and puerperal period and their demographic characteristics; pelvic organ prolapse quantitation (POP-Q) and pelvic floor muscle electrophysiology (EP) examination were conducted in postpartum women at 6-8 weeks. Results: Vaginal delivery was a risk factor for anterior pelvic organ prolapse (POP) (OR 7.850, 95% confidence interval (CI) 5.804-10.617), posterior POP (OR 5.990, 95% CI 3.953-9.077), anterior and posterior stage II POP (OR 6.636, 95% CI 3.662-15.919), and postpartum urinary incontinence (UI) (OR 6.046, 95% CI 3.894-9.387); parity was a risk factor for anterior POP (OR 1.397,95% CI 0.889-2.198) and anterior and posterior stage II POP (OR 4.162, 95% CI 2.125-8.152); age was a risk factor for anterior POP (OR 1.056, 95% CI 1.007-1.108) and postpartum UI (OR 1.066, 95% CI 1.014-1.120); body mass index (BMI) was a risk factor for postpartum UI (OR 1.117, 95% CI 1.060-1.177); fetal birth weight was a risk factor for posterior POP (OR 1.465, 95% CI 1.041-2.062); and the frequency of pregnancy loss was a risk factor for apical POP (OR 1.853, 95% CI 1.060-3.237). Conclusion: Pelvic floor muscle EP is a sensitive index of early pelvic floor injury. The changes in muscle strength and fatigue degree coexist in different types of postpartum PFD, and each has its own characteristics.

Prevalence and sociodemographic correlates of urinary incontinence in Japanese women: A web-based cross-sectional study

BACKGROUND

Epidemiological studies on urinary incontinence that used a validated international standard questionnaire are limited in Japan, and few studies have examined the sociodemographic and behavioral correlates of urinary incontinence.

OBJECTIVE

The aim of this study was to estimate the prevalence of urinary incontinence according to the Japanese version of the International Consultation on Incontinence Questionnaire-Short Form, and its sociodemographic and behavioral correlates among Japanese women.

DESIGN

A web-based cross-sectional study.

METHODS

A randomly sampled cross-sectional Internet survey was conducted in Japan among 3030 women aged 20-64 years. The International Consultation on Incontinence Questionnaire-Short Form score, sociodemographic, body mass index, medical and childbirth history, practice of pelvic floor muscle training, and medical care use were obtained. Descriptive statistics, the chi-square test, and forced-entry logistic regression analysis were used in data analysis.

RESULTS

Participants' average age was 43.4 years, and the response rate was 32.9%. The prevalence of urinary incontinence was 25.5%, and it increased with age. Stress urinary incontinence was the most common subtype (57.4%), followed by urge urinary incontinence (20.3%) and mixed urinary incontinence (16.7%). Less than 5% of those with urinary incontinence had experience with pelvic floor muscle training and medical care use. Middle-aged and older (p < 0.001), overweight and obesity (p < 0.001), vaginal delivery status (p < 0.001), low back pain (p = 0.008), and previous pelvic floor muscle training engagement (p < 0.001) were significantly associated with urinary incontinence.

CONCLUSION

Increasing population awareness of urinary incontinence from an early age and developing effective interventions for the identified at-risk groups, such as the middle-aged and older, those with overweight and obesity, and those with previous pregnancies, are urgently needed.

How do reproductive history and anthropometry in midlife relate to later risk of pelvic organ prolapse? A prospective cohort study

INTRODUCTION AND HYPOTHESIS

The objective was to examine the association between reproductive and anthropometric factors and later risk of pelvic organ prolapse (POP).

METHODS

We carried out a prospective cohort study including 11,114 female nurses > 44 years from the Danish Nurse Cohort. In 1993, the study population was recruited through the Danish Nurse Organization and self-reported data on age, height, weight, age at menarche, age at first birth and number of childbirths were obtained. POP diagnosis was obtained from the National Patient Registry. Risk of POP was estimated using COX regression and presented as hazard ratios (HR) with 95% confidence intervals (CI).

RESULTS

Overall, 10% of the women received a diagnosis of POP within a median follow-up of 22 years. A 4% increase in risk of POP was seen for each increasing BMI (kg/m²) unit at baseline. Compared to women of normal weight, higher risks of POP were seen in overweight (HR 1.18: 1.02-1.36) and obese women (HR 1.33: 1.02-1.74), while underweight had a lower risk (HR 0.51: 0.27-0.95). Compared to women with one childbirth, women with no childbirths had a reduced risk of 57% while increased risks of 46%, 78% and 137% were observed in women with two, three and four childbirths. Women with menarche before the age of 12 tended to have a higher risk of POP as did women who were 30-33 years at their first childbirth.

CONCLUSIONS

POP is a common health problem in women, and BMI and number of childbirths are strong predictors.

Epidemiology of Constipation in Elderly People in Parts of China: A Multicenter Study

Purpose

To investigate the epidemiological characteristics of constipation in people aged 65 years and older in several regions of China.

Patients and Methods

A cross-sectional study based on a cluster sampling design was conducted in four cities of China: Tianjin, Xiamen, Cangzhou and Harbin. A total of 5,222 cases (age ≥ 65 years) were recruited, and the survey was conducted via centralized and household questionnaires that included the following: basic demographic characteristics such as sex, age, education, marital status, living status and occupation; social activities; duration of sleep at night; duration of menstruation and delivery times (in females); and if the participant had constipation symptoms, the severity of constipation. Constipation was diagnosed according to the Rome IV criteria.

Results

Of the 5,222 participants, 919 were diagnosed with constipation. The prevalence of constipation was 17.60% in elderly people ≥65 years old. Prevalence increased with age and was significantly higher in females than males (P < 0.05). Prevalence was lower in the manual compared to the non-manual worker group, and significantly increased with decreasing duration of night sleep (P < 0.05). Older age, female sex and shorter sleep duration at night were risk factors for constipation in elderly people.

Conclusion

The prevalence of constipation in the elderly people in four cities of China was 17.60%, and was significantly affected by age, sex and sleep duration at night.

Prevalence of pelvic floor dysfunction in women in Riyadh, Kingdom of Saudi Arabia: A cross-sectional study

Objective:

Pelvic floor dysfunction has a high prevalence among women worldwide. However, in the Kingdom of Saudi Arabia, it is underreported. Thus, we aimed to estimate the prevalence and risk factors of pelvic floor dysfunction in women in the Kingdom of Saudi Arabia.

Methods:

We conducted a cross-sectional study on literate non-pregnant women aged ⩾18 years who agreed to participate in our survey. We used the validated and translated Australian pelvic floor questionnaire and conducted a multivariate logistic regression analysis to assess the risk factors of pelvic floor dysfunction.

Results:

A total of 824 participants completed the questionnaire. While 60.2% of the participants had pelvic floor dysfunction, 67.7% reported signs of bowel dysfunction. Urinary dysfunction, prolapse, and sexual dysfunction were present in 44.1%, 67.7%, and 55.4% of the participants, respectively. Age, high body mass index, chronic medical illness, heavy weight lifting, and multiparity were found as the risk factors of bladder function problems. Meanwhile, chronic medical illness, heavy weight lifting, and multiparity were found as the risk factors of bowel dysfunction and prolapse. Age group and marital status were the independent factors associated with sexual dysfunction.

Conclusion:

We noted a high rate of pelvic floor dysfunction in the Kingdom of Saudi Arabia, which calls for the need to provide holistic approaches for the prevention and management of pelvic floor dysfunction among women.

Assessment of the Elastographic and Electromyographic of Pelvic Floor Muscles in Postmenopausal Women with Stress Urinary Incontinence Symptoms

Background. Shear wave elastography is an effective method for studying the condition of various musculoskeletal soft tissues. The primary aim of this study was the objective elastographic and electromyographic assessment of the pelvic floor during the rest and contraction of the pelvic floor muscles (PFM) in postmenopausal women. Methods. This was a prospective observational study that was carried out at the University Hospital in Wroclaw, Poland, between January 2017 and December 2019. Patients. The target group of the study included postmenopausal women with stress urinary incontinence. The primary outcomes were the features of the elastographic assessment of the pelvic floor during rest and contraction of the PFM obtained using shear wave elastography. Results. Based on the inclusion and exclusion criteria for the study, 14 patients took part in the measurements. There was a significant difference between the elastographic assessment of the pelvic floor during rest and contraction of the PFM at all locations in front of the urethra. No statistically significant correlation was found between the results of elastography and the bioelectrical activity of PFM. Conclusion. The elasticity of the periurethral structures is higher during active pelvic floor muscle contraction than at rest, it seems that shear wave elastography is an effective test that objectively assesses the strength of PFM contraction.

Association between acute graft pyelonephritis and kidney graft survival: A single-center observational study

The association between acute graft pyelonephritis (AGPN) and graft failure in kidney transplant recipients (KTR) remains controversial. In this single-center observational study, we aimed to assess the incidence of AGPN as a time-dependent posttransplantation event. We also examined the association between the diagnosis of AGPN and graft outcomes. In total, we evaluated 1480 patients who underwent kidney transplantation between January 2007 and December 2017. During a median follow-up of 5.04 years, we observed 297 AGPN episodes that occurred in 158 KTR. To evaluate the association between AGPN and clinical outcomes, we performed Cox proportional hazards regression analyses in which AGPN was entered as a time-dependent covariate. AGPN was independently associated with an increased risk of graft loss (hazard ratio = 1.66; 95% confidence interval [CI]: 1.05-2.64, p < .03) and a persistently decreased eGFR (fixed effect on intercept: -2.29 ml/min/1.73 m² ; 95% CI: from -3.23 to -1.35, p < .01). However, neither mortality nor biopsy-proven acute rejection was found to correlate with AGPN. Moreover, recurrent AGPN episodes did not appear to have an additive detrimental impact on graft loss. These data represent a promising step in understanding whether AGPN prevention may decrease the risk of graft loss in KTR.

The Relationship Between Pelvic Floor Function and Sexual Function in Perimenopausal Women

INTRODUCTION

Perimenopausal women with pelvic floor dysfunction have worse sexual function than women with functional pelvic floor muscle (PFM), especially in terms of libido, orgasm, sexual satisfaction, and total Female Sexual Function Index (FSFI) scores.

AIM

To explore the relationship between pelvic floor muscle function, hormone levels and sexual function in perimenopausal women.

METHODS

An analytical cross-sectional study was conducted in 252 women aged 40-55 without pelvic floor disease with FSFI, pelvic floor muscle strength and the hormone levels.

MAIN OUTCOME MEASURE

The principle aim was to determine the relationships between sexual dysfunction, PFM strength, and hormone levels.

RESULTS

In the functional PFM group, the proportion of menopausal hormone therapy was higher. The proportion of overweight in the dysfunctional PFM group was higher, and had more sexual desire disorder, more orgasm disorder, lower sexual satisfaction, and poor FSFI scores. The correlation between PFM strength, sexual function and female sex hormones suggested that PFM strength and libido, sexual satisfaction and FSFI score are significantly positively correlated, while PFM strength and sexual arousal disorder and vaginal lubricity had a positive correlation. In the multivariate analysis of the risk of sexual dysfunction among perimenopausal women, the higher the PFM strength, the lower the risk of sexual dysfunction.

CONCLUSIONS

Perimenopausal women with pelvic floor dysfunction have worse sexual function than women with functional PFM, especially in obese women, those with central adiposity, and not using hormone replacement therapy. The PFM strength was weakly positively correlated with sexual arousal, orgasm, sexual satisfaction, and FSFI score. Zhuo Z, Wang C, Yu H, et al.

Differential estrogen-related responses in myofiber cross-sectional area of pelvic floor muscles in female rats

OBJECTIVE

To determine the role of estrogens in myofiber cross-sectional area (CSA) of the pubococcyegeus (Pcm) and iliococcygeus muscles (Icm).

METHODS

In Experiment 1, we excised the Pcm and Icm during the metestrus and proestrus stages of the estrous cycle to measure the myofiber CSA. In Experiment 2, we allocated other rats into the following groups: sham (Sh), ovariectomized (OVX), OVX plus 1,4,6-androstatriene-3,17-dione (ATD; OVX + ATD), an aromatase inhibitor, and OVX plus estradiol benzoate (OVX + EB). We carried out appropriate statistical tests to determine significant differences (p ≤ 0.05) in variables measured for both Experiments.

RESULTS

The Pcm myofiber CSA at proestrus was higher than at metestrus, while the Icm myofiber CSA did not change. Ovariectomy increased the Pcm myofiber CSA, which was exacerbated with the ATD administration. The EB supplementation successfully reversed the ovariectomy-induced enlargement of the CSA. No significant changes were detected for the Icm myofiber CSA.

CONCLUSIONS

Fluctuating ovarian steroid levels at the estrus cycle significantly influence the CSA myofiber of the Pcm but not that of the Icm. Estrogen actions, having a gonadal or extragonadal origin, influence importantly the CSA of the Pcm.

Inter- and intrarater reliability of unidigital and bidigital vaginal palpation to evaluation of maximal voluntary contraction of pelvic floor muscles considering risk factors and dysfunctions

AIMS

To evaluate inter- and intrarater reliability of unidigital and bidigital vaginal palpation of pelvic floor muscle (PFM) maximal voluntary contraction (MVC) according to PFM risk factors and dysfunctions.

METHODS

A total of 187 women were recruited and evaluated by two examiners. Both performed the evaluation of MVC with unidigital and bidigital palpation, graded by Modified Oxford Scale. After 7-10 days, one examiner repeated the assessment. To analyze reliability by Cohen's linear Kappa (κw), participants were allocated into different groups according to: body mass index (BMI), menopause, parity, type of delivery and PFM dysfunctions, as pelvic organ prolapse (POP), constipation, urgency, urgency urinary incontinence, pelvic pain, and stress urinary incontinence.

RESULTS

Inter-rater reliability of unidigital palpation was considered fair (κw = 0.21-0.40) to moderate (κw = 0.41-0.60) according to BMI, postmenopausal status, parity, type of delivery, and PFM dysfunctions. Inter-rater reliability of bidigital palpation varied from none (κw = 0.00-0.20) to moderate for all risk factors and PFM dysfunctions. Intra-rater reliability of unidigital palpation was considered fair only for women with POP (κw = 0.37) and moderate to substantial (κw = 0.61-0.80) to all other variables. Intra-rater reliability of bidigital palpation ranged from moderate to almost perfect (κw = 0.81-1.00).

CONCLUSIONS

When performing vaginal palpation, physiotherapists must consider the way that is performing the evaluation, as some PFM risk factors and dysfunctions could influence the inter- and intrarater reliability of unidigital and bidigital palpation.

Do women runners report more pelvic floor symptoms than women in CrossFit®? A cross-sectional survey

INTRODUCTION AND HYPOTHESIS

Women who perform high-impact activities might be at greater risk of pelvic floor dysfunction (PFD) than those participating in low-impact exercise; however, little is known about whether PFD is more common in one type of high-impact activity than another. The aim of this study was to compare the prevalence of PFD symptoms in women who engage in high-impact activity compared with CrossFit®-brand training (CF).

METHODS

An online survey collected data from 1,379 women (521 runners, 858 CF) on exercise participation, parity, and PFD symptoms, via the Pelvic Floor Distress Inventory (PFDI-20). Specific questions from each PFDI-20 subscale further investigated symptoms of pelvic organ prolapse (POP), anal incontinence (AI), as well as stress (SUI) and urgency (UUI) urinary incontinence.

RESULTS

Symptoms of POP and AI were significantly higher in runners (POP 12.7%, AI 34.0%) than in CF (POP 7.8%, p = 0.003; AI 27.7%, p = 0.014). There was no significant difference in SUI symptoms between groups (37.0% vs 41.0% respectively, p = 0.141). Vaginally parous runners reported significantly more symptoms of POP (19.0% vs 12.2%, p = 0.023), AI (39.3% vs 27.2%, p = 0.001), and UUI (36.3% vs 29.0%, p = 0.037) than CF.

CONCLUSION

Women, particularly parous women, who participate in running, have a higher prevalence of POP and AI symptoms than women who participate in CF. This suggests that CrossFit®-brand training might not be more detrimental to PFD symptoms than other high-impact activity, such as running. This study does not conclude a pelvic floor health benefit of one exercise over another, but highlights that exercise options can be provided to women.

Three-dimensional ultrasound evaluation of the pelvic floor in postmenopausal women using hormone therapy

OBJECTIVE

To evaluate the three-dimensional (3D) ultrasound characteristics of the pelvic floor muscles (PFM) in two groups of postmenopausal women: users and nonusers of menopausal hormone therapy (MHT).

STUDY DESIGN

Observational, cross-sectional cohort study.

MAIN OUTCOME MEASURES

In this study 226 sexually active heterosexual women, aged 45-60 years with amenorrhea >12 months and without clinical pelvic floor disorders or urinary incontinence were included. Women using MHT ≥ 6 months were classified as systemic users. PFM strength was assessed by digital vaginal palpation and scored on the Modified Oxford Scale. Biometry of the PFM was performed by 3D transperineal ultrasound for evaluation of total urogenital hiatus area, transverse and anteroposterior diameters, and levator ani muscle thickness.

RESULTS

The participants were divided into users (n = 78) and nonusers (n = 148) of MHT. There were no differences in clinical or anthropometric parameters between groups. The mean age was 55 years and the time since menopause was six years in both groups. The mean duration of MHT use was 43.4 ± 33.3 months. Users of MHT had greater levator ani muscle thickness (p = 0.001) and higher PFM strength (p = 0.029) than nonusers. Risk analysis adjusted for age, time since menopause, BMI, parity, and type of delivery showed an association of MHT use with greater levator ani muscle thickness (OR = 2.69; 95% CI 1.42-5.11, p = 0.029), and higher PFM strength (OR = 1.78; 95% CI1.01-3.29, p = 0.046). There was a weak positive correlation between levator ani muscle thickness and duration of MHT use (r = 0.25, p = 0.0002) and PFM strength (r = 0.12, p = 0.043).

CONCLUSIONS

Postmenopausal women using MHT had a greater levator ani muscle thickness associated with higher PFM strength than nonusers.

Cardiovascular responses to pelvic floor muscle contraction in healthy women: Prospective study

OBJECTIVE

Analyze the acute heart rate and blood pressure responses to two protocols of pelvic floor muscles contractions in premenopausal and postmenopausal women.

METHODS

Fifty-four women without pelvic floor muscles disorders were eligible and allocated into two groups: premenopausal and postmenopausal. The groups underwent two protocols and the pelvic floor muscle endurance, heart rate, and blood pressure values were monitored. Both protocols included 10 pelvic floor muscles contractions; one series contained contractions lasting 5 s with 5 s of rest between each contraction and the other series contained contractions lasting 10 s with 10 s of rest.

RESULTS

In both groups, there was a significant increase in the heart rate during pelvic floor muscles contractions (premenopausal: 71.0 ± 7.3 and 80.3 ± 7.7; postmenopausal: 65.4 ± 6.6 and 73.6 ± 6.6, at rest and contractions peak, respectively) and in systolic blood pressure immediately after the contractions. The observed values during exercise returned to basal values seconds after the contractions. A positive correlation between heart rate and vaginal squeeze pressure (r = 0.45, p = 0.0007 and r = 0.48, p = 0.0003, 5- and 10-s series, respectively) was observed.

CONCLUSION

The proposed protocol of isometric pelvic floor muscles contractions caused an increase in heart rate and blood pressure within the normal range and might not represent a cardiovascular risk for healthy postmenopausal women without urinary incontinence and without cardiovascular dysfunctions.

Advances in surgical strategies for prolapse

Pelvic floor dysfunctions are a complex condition in elderly women; pelvic organ prolapse, urinary or fecal incontinence, constipation, pelvic pain, and sexual dysfunction are common problems. The goal of surgical treatment is functional reconstruction with symptom management and repair of anatomic defects. The recent advancements in surgical treatment of pelvic floor dysfunction allow several good options for choosing the best surgery for each patient. The vaginal procedure is traditionally the gold standard approach for elderly patients, but abdominal surgery is increasing as a mini-invasive approach and the robotic approach is gaining acceptance for treatment of pelvic floor dysfunctions. In elderly individuals, a multitude of factors affects the final result of any reconstructive surgery such as postmenopausal or aging-associated changes in muscle tone and nerve function or changes in the function of the bladder or of the rectum: an understanding of the underlining functional status of pelvic organs is very important in aging women before proceeding to surgery. In this context, pelvic floor dysfunction, particularly in elderly women, should be addressed in a multidisciplinary manner and, at the forefront, centers for surgical planning could be helpful to perform safer, patient-tailored surgery.

Age-associated differences in macrophage response in a vaginal wound healing rat model

INTRODUCTION AND HYPOTHESIS

Surgical treatment of pelvic organ prolapse often includes the use of patients' vaginal connective tissue. Wound healing appears to play an important part in the success of such procedures. The aim of this study was to describe the effect of age on inflammatory processes, specifically macrophage response, involved in vaginal wound healing.

METHODS

Twenty-five young (12 weeks old) and 25 old (12 months old) virgin female Fischer rats underwent a standardized 9-mm posterior midline vaginal incision. Tissue samples were taken for histological analysis on days 1, 3, 7, 14 and 30 post-injury. Parameters evaluated included wound area, macrophage number and expression of inflammatory markers including tumor necrosis factor alpha (TNFa), inducible nitric oxide synthase (iNOS), CCR7/CD197, arginase I and CD163/M130.

RESULTS

Microscopic examination of the vaginal wounds over time demonstrated a clear difference between young and old rats in spontaneous healing capacity. The average wound area in young rats 1 day after injury was significantly smaller than in old rats (16.5 ± 1.7 vs. 23.8 ± 1.5 mm², P < 0.05). At 3 days post-injury, wounds were closed in young rats but still open in old rats (wound area: 13.5 ± 1.5 mm²). Old rats demonstrated a more excessive and sustained macrophage response compared with young rats. They also demonstrated a disordered pattern of macrophage expression over time, with a prolonged expression of TNFa and iNOS in the tissue and a disordered M2 macrophage response.

CONCLUSION

Excessive and prolonged macrophage response in older rats may contribute to poor wound healing in the vagina.

Parity: a risk factor for decreased pelvic floor muscle strength and endurance in middle-aged women

INTRODUCTION AND HYPOTHESIS

The incidence of pelvic floor muscle (PFM) dysfunction increases rapidly with menopause and aging. Despite the raised magnitude and prevalence of pelvic floor disorders in middle-aged women, the risk factors underlying PFM dysfunction still remain to be identified. PFM function can be clinically measured as the maximum strength and endurance using manometry. The aim of this study was to evaluate PFM function in terms of strength and endurance by perineometer and to assess the risk factors that decrease PFM strength and endurance in middle-aged women.

METHODS

This was a cross-sectional study. Overall, 125 parous women (age 40-60 years) completed the study. A questionnaire was used to collect information on several demographic and obstetric variables. The Peritron perineometer measured PFM strength and endurance. Multiple linear regression analysis was used to evaluate the effects of sociodemographic variables on PFM function.

RESULTS

Both average strength of PFMs and maximum muscle strength significantly reduced as the number of parity increased. Average and maximum strength of PFMs showed a significant difference between women with parities of two and one (β = -0.435, p < .001; β = -0.441, p < 0.001, respectively). Both were even more influenced in women with parity of three (β = -0.503, p < .001; β = -0.500, p < .001). However, PFM endurance did not decrease with increasing parity number until the parity of two; however, it decreased in women with parity of three (β = -0.302, p < 0.05).

CONCLUSION

Parity appeared to have a dominant influence on weakness of PFM, and strength was more significantly associated with parity than endurance in middle-aged women.

Prevalence of incontinence among cognitively impaired older residents in long-term care facilities in East Asia: A cross-sectional study

AIM

The current study was an international cross-sectional study comparing the prevalence of incontinence among cognitively impaired older residents in long-term care facilities in East Asia, including Japan, Korea, China, Taiwan and Thailand between 2015 and 2016.

METHODS

Participants were cognitively impaired older residents in long-term care facilities. Demographic data were collected. The Clinical Dementia Rating scale was used to assess dementia severity, and the Barthel Index was used as a surrogate measure of incontinence and toilet use dependence. The prevalence of urinary incontinence and fecal incontinence were examined. Multiple logistic regression analysis was used to predict incontinence and toilet use dependence.

RESULTS

We analyzed data from 662 participants (age 82.6 ± 9.9 years, 57.6% women). The prevalence of urinary incontinence ranged from 10.1% in Taiwan to 71.0% in Korea. The prevalence of fecal incontinence varied from 4.0% in Taiwan to 57.0% in Korea. A higher Clinical Dementia Rating score was a significant predictor of urinary and fecal incontinence and toilet use dependence (P < 0.0001).

CONCLUSIONS

The current survey showed a high prevalence of incontinence in long-term care residents in East Asia, and identified challenges for future studies. Development of clinical guidelines for incontinence care in cognitively impaired older persons is urgently required. Geriatr Gerontol Int 2019; 19: 444-450.

Keeping the pelvic floor healthy

Female pelvic floor muscles form a diaphragm that spans the entire pelvic cavity. They consist of the fibers of the coccygeus and the levator ani muscles, the latter of which is composed of five parts. Together with their fascia, the pelvic floor muscles provide support for the urethra, the vagina, and the rectum and constrict the urethral, vaginal, and anal orifices. Alterations in the composition of the pelvic floor muscles at menopause appear to affect their properties and, thereby, their ability to function adequately. This can lead to an increased prevalence in urinary incontinence and other lower urinary tract dysfunction, pelvic organ prolapse, and genitourinary syndrome of menopause. This article aims to define the pelvic floor muscles and functions and to summarize the direct and indirect changes to women's pelvic floor muscles during and after menopause and through aging. A particular focus is also given to the evidence-based literature on how to keep pelvic floor muscles healthy during menopause and in postmenopause using conservative management therapy.

Addressing Vulvovaginal Atrophy (VVA)/Genitourinary Syndrome of Menopause (GSM) for Healthy Aging in Women

Vaginal health is an essential component of active and healthy aging in women at midlife and beyond. As a consequence of hormonal deprivation and senescence, the anatomy and function of urogenital tissues are significantly affected and vulvovaginal atrophy (VVA) may occur. In a high proportion of postmenopausal women, progressive and chronic VVA symptoms have a strong impact on sexual function and quality of life. The new definition of genitourinary syndrome of menopause (GSM) comprises genital symptoms (dryness, burning, itching, irritation, bleeding), sexual symptoms (dyspareunia and other sexual dysfunctions) and urinary symptoms (dysuria, frequency, urgency, recurrent urinary infections). Many variables (age, sexual activity and partnership status) influence the clinical impact VVA/GSM symptoms and attitudes of elderly women to consult for receiving effective treatments. Psychosocial factors play a critical role in sexual functioning, but the integrity of the urogenital system is as well important affecting many domains of postmenopausal women's health, including sexual function. Several international surveys have extensively documented the need to improve VVA/GSM management because of the strong impact on women's daily life and on couple's intimacy. Health care providers (HCPs) need to be proactive in the early recognition of VVA/GSM in order to preserve urogenital and sexual longevity, by using hormonal and non-hormonal strategies. The clinical diagnosis is based on genital examination to identify objective signs and on the use of subjective scales to rate most bothersome symptoms (MBS), especially vaginal dryness. Recent studies point to the importance of addressing VVA/GSM as a potential early marker of poor general health in analogy with vasomotor symptoms. Therefore, a standard of VVA/GSM care in elderly women is desirable to enhance physical, emotional and mental well-being.

Prevalence of Stress Urinary Incontinence in Women with Premature Ovarian Insufficiency

Background: To determine the prevalence of stress urinary incontinence (SUI) and associated factors in women with premature ovarian insufficiency (POI). Materials and Methods: The study included 149 patients with POI and 303 control women without POI. Age, body mass index (BMI), gestational history, time since onset of POI, and status of hormone therapy (HT) for POI were recorded. Results: There was no statistical difference in the mean age, BMI, and parity between the two groups. The prevalence of SUI in the POI group tended to be higher than that in the control group (20.9%, 30/149 vs. 16.2%, 49/303), although not significantly (p = 0.297). About 41.6% (62/149) of patients with POI received HT. Patients with POI and SUI were older (p = 0.018) and had higher BMI (p = 0.007) than women with POI without SUI (p = 0.007). Compared to nulliparas, primiparas were more likely to have SUI (p = 0.046). However, SUI developed irrespective of time since onset of oligomenorrhea/amenorrhea or HT use. Furthermore, regression analysis showed that the prevalence of SUI was higher in women 30-39 years of age (odds ratio [OR] = 3.27, p = 0.002) and older than 40 years (OR = 7.78, p = 0.001). Primiparas (OR = 2.89, p = 0.001) and vaginal delivery (OR = 2.58, p = 0.023) were associated with SUI. Conclusions: The prevalence of SUI was fairly high among patients with POI, and age, parity, and vaginal delivery were the main risk factors. However, duration of POI and HT use had no effect on SUI. Increasing awareness of the importance of urinary system health in this population will improve the quality of life for these women.

Female Sexual Function at Midlife and Beyond

Sexual function is an important component of quality of life for women. Midlife poses several challenges to optimal sexual function and intimacy for women. In addition to anatomic factors related to estrogen deficiency, such as genitourinary syndrome of menopause, vulvovaginal atrophy, and pelvic organ prolaps, psychosocial factors, including prior sexual trauma, play an important role in sexual function in women. Several treatments have emerged for female sexual dysfunction; long-term studies and head-to-head comparisons are lacking.

Climacteric women at work: What lurks behind poor occupational quality of life?

Physical and psychological changes during menopausal transition may affect various aspects of everyday functioning including women's work ability and work productivity. Presence of menopausal symptoms has been well-acknowledged to negatively affect quality of life (QOL). However, data on factors associated with occupational QOL among women at this period of life are lacking. The authors' purpose in this study was to evaluate factors affecting occupational QOL in a sample of employed mid-life women who are experiencing menopause. The authors performed a cross-sectional study among 335 employed women aged 40 to 65 years from Serbia. Socio-demographic questionnaire, Utian's Quality of Life Scale, and Beck's Depression Inventory were used in data collection. Women's average monthly household income and educational level were positively correlated, while having uterine prolapse was negatively associated with occupational QOL. Significant regression models assessing impact of gynecological illnesses and menopause-specific symptoms on occupational QOL (direct value and categories-below vs. above mean) showed that having insomnia, uterine prolapse, and genital inflammations may differentiate "good" from "poor" occupational QOL. Uterine prolapse, genital inflammation, and insomnia were associated with worse occupational QOL among working women in menopausal transition.

Symptoms of menopause - global prevalence, physiology and implications

The symptoms of menopause can be distressing, particularly as they occur at a time when women have important roles in society, within the family and at the workplace. Hormonal changes that begin during the menopausal transition affect many biological systems. Accordingly, the signs and symptoms of menopause include central nervous system-related disorders; metabolic, weight, cardiovascular and musculoskeletal changes; urogenital and skin atrophy; and sexual dysfunction. The physiological basis of these manifestations is emerging as complex and related, but not limited to, oestrogen deprivation. Findings generated mainly from longitudinal population studies have shown that ethnic, geographical and individual factors affect symptom prevalence and severity. Moreover, and of great importance to clinical practice, the latest research has highlighted how certain menopausal symptoms can be associated with the onset of other disorders and might therefore serve as predictors of future health risks in postmenopausal women. The goal of this Review is to describe in a timely manner new research findings on the global prevalence and physiology of menopausal symptoms and their impact on future health.

Urinary Urgency in Working Women: What Factors Are Associated with Urinary Urgency Progression?

BACKGROUND

Urinary urgency is the primary symptom of overactive bladder (OAB). This study aimed to identify targets for effective intervention to delay progression of urinary urgency.

MATERIAL AND METHODS

Secondary analyses of data from a study conducted with female employees of a large academic medical center were conducted. Women were ≥18 years and nonpregnant at the time of the survey. An online questionnaire obtained demographic information, presence of lower urinary tract symptoms, and toileting behaviors. Bivariate analyses and multivariate logistic regression were applied to explore factors related to different stages of urinary urgency.

RESULTS

Four stages of urinary urgency were constructed: (1) Stage 1: no urinary symptoms (n = 20), (2) Stage 2: continent but urinary urgency reported (n = 19), (3) Stage 3: nonsevere urgency urinary incontinence (UUI) (incontinent but leakage ≤1/day, n = 74); and (4) Stage 4: severe UUI (leakage ≥1/day, n = 26). In multivariate analyses, older women were more likely to be in Stage 3 than in Stage 2 (aOR 1.053, 95% CI 1.012-1.096). Women who lost urine with defecation were more likely to be in Stage 4 than Stage 3 (aOR 3.828, 95% CI 1.921-7.629). Women who habitually strained to empty the bladder faster were more likely to be in Stage 4 than in Stage 3 (aOR 6.588, 95% CI 1.317-32.971).

CONCLUSIONS

Losing urine with defecation and making the bladder empty faster by pushing down should be explored as intervention targets to prevent women from progressing from Stage 3 to Stage 4.

Muscle function of the pelvic floor in healthy, puerperal women with pelvic floor dysfunction

OBJECTIVES

To understand the function of the pelvic floor muscles (PFM) at different ages in healthy women and in puerperal women with pelvic floor dysfunctions (PFD) and to ascertain whether there are differences among them.

MATERIAL AND METHODS

A descriptive cross-sectional study was conducted between June 2014 and September 2016 and included 177 women, 70 of whom had no symptoms of PFD, 53 primiparous mothers in late postpartum and 54 with PFD. The function of the PFM was measured through vaginal palpation (quality of the contraction); manometry (force); dynamometer (tone, strength, and response to stretching), and surface electromyography (neuromuscular activity and resistance).

RESULTS

The healthy women showed superior values for PFM tone, maximum strength, neuromuscular activity and resistance than the puerperal mothers and the women with PFD (P<.01). The puerperal women and those with PFD showed similar functional PFM values (P>.05). The muscle function of the healthy women did not vary significantly with age, except in the case of tone, which was lower in the women older than 46 years (P=.004).

CONCLUSIONS

Age and births decrease the baseline tone of the PFM in healthy women. Therefore, lower strength, resistance and neuromuscular activity appear to be the main difference between the PFM of women with PFD and the PFM of healthy women.

Preventing urinary tract infections after menopause without antibiotics

Urinary tract infections (UTIs) are the most common bacterial infections in women, and increase in incidence after the menopause. It is important to uncover underlying abnormalities or modifiable risk factors. Several risk factors for recurrent UTIs have been identified, including the frequency of sexual intercourse, spermicide use and abnormal pelvic anatomy. In postmenopausal women UTIs often accompany the symptoms and signs of the genitourinary syndrome of menopause (GSM). Antimicrobial prophylaxis has been demonstrated to be effective in reducing the risk of recurrent UTIs in women, but this may lead to drug resistance of both the causative microorganisms and the indigenous flora. The increasing prevalence of Escherichia coli (the most prevalent uropathogen) that is resistant to antimicrobial agents has stimulated interest in novel non-antibiotic methods for the prevention of UTIs. Evidence shows that topical estrogens normalize vaginal flora and greatly reduce the risk of UTIs. The use of intravaginal estrogens may be reasonable in postmenopausal women not taking oral estrogens. A number of other strategies have been used to prevent recurrent UTIs: probiotics, cranberry juice and d-mannose have been studied. Oral immunostimulants, vaginal vaccines and bladder instillations with hyaluronic acid and chondroitin sulfate are newer strategies proposed to improve urinary symptoms and quality of life. This review provides an overview of UTIs' prophylaxis without antibiotics, focusing on a practical clinical approach to women with UTIs.

Assessment of lower urinary tract symptoms in different stages of menopause

[Purpose] To assess lower urinary tract symptoms in different stages of menopause and the quality of life of females with incontinence. [Subjects and Methods] The sample consisted of 302 females, aged between 40 and 56 years, divided into three groups: PRE (n= 81), PERI (n= 108) and POST (n= 113). This was a cross-sectional, analytical, observational study. Data were collected by assessment chart and conducting the International Consultation on Incontinence Questionnaire-Short Form. [Results] Most of the women had less than 10 years of schooling and were married. In PERI and POST menopause, the most frequent lower urinary tract symptoms were urinary urgency and stress incontinence. The PRE group did not exhibit nocturia, urge incontinence or urinary urgency, and had the lowest symptoms frequency. In the three stages, stress incontinence was the most prevalent symptom. Of the three menopause stages, PERI had a greater impact on urinary incontinence according to the International Consultation on Incontinence Questionnaire. [Conclusion] The presence of lower urinary tract symptoms can vary across the different stages of menopause and the urinary incontinence was the most frequent complaint. Moreover, it was observed that quality of life was more affected in the perimenopause stage.

First assessment of short-term efficacy of Er:YAG laser treatment on stress urinary incontinence in women: prospective cohort study

OBJECTIVES

This is the first assessment of efficacy and safety of the Er:YAG laser in the treatment of stress urinary incontinence. The aim of this study was to assess the short-term outcome of a non-invasive laser treatment for mild-to-severe stages of this condition and to check its applicability in different body mass index and age groups.

METHODS

A prospective cohort, single-center study at the Ob/Gyn Clinic, Zagreb, Croatia recruited a consecutive sample of 73 female patients suffering from stress urinary incontinence. The procedure was performed with a 2940-nm Er:YAG laser (XS Dynamis, Fotona, Slovenia) designed to achieve heating up of vaginal mucosa to around 60°C, 500-700 μm in depth.

RESULTS

The score in the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form was reduced to a median of 46% (95% confidence interval 33-67%; p < 0.001). The reduction was significantly higher in women with normal body mass index (67%) than in overweight women (25%), as well as in women younger than 39 years (100%) compared with those older than 60 years (8%) (p < 0.001). No serious adverse events were noticed.

CONCLUSION

This study of Er:YAG laser therapy in women has demonstrated a clinically relevant, short-term improvement of stress urinary incontinence, with minimal adverse events of a transient nature.

Menopause and Sexuality

Sexuality is an important component in the lives of menopausal women. Despite the importance of sexual function in menopausal women, sexual dysfunction increases with age. Age-related decline in sexual function may significantly reduce quality of life, making recognition of sexual dysfunction by physicians important for getting menopausal women effective care. Sexual dysfunction can result from multiple etiologies including psychosocial factors, medication side effects, vulvovaginal atrophy, chronic illness, or hypoactive sexual desire disorder. Discovering the etiology and identifying modifiable factors of the sexual function will help define appropriate treatment.

Pelvic floor dysfunction, and effects of pregnancy and mode of delivery on pelvic floor

Pelvic floor dysfunction (PFD), although seems to be simple, is a complex process that develops secondary to multifactorial factors. The incidence of PFD is increasing with increasing life expectancy. PFD is a term that refers to a broad range of clinical scenarios, including lower urinary tract excretory and defecation disorders, such as urinary and anal incontinence, overactive bladder, and pelvic organ prolapse, as well as sexual disorders. It is a financial burden on the health care system and disrupts women's quality of life. Strategies applied to decrease PFD are focused on the course of pregnancy, mode and management of delivery, and pelvic exercise methods. Many studies in the literature define traumatic birth, usage of forceps, length of the second stage of delivery, and sphincter damage as modifiable risk factors for PFD. Maternal age, fetal position, and fetal head circumference are nonmodifiable risk factors. Although numerous studies show that vaginal delivery affects pelvic floor structures and their functions in a negative way, there is not enough scientific evidence to recommend elective cesarean delivery in order to prevent development of PFD. PFD is a heterogeneous pathological condition, and the effects of pregnancy, vaginal delivery, cesarean delivery, and possible risk factors of PFD may be different from each other. Observational studies have identified certain obstetrical exposures as risk factors for pelvic floor disorders. These factors often coexist; therefore, the isolated effects of these variables on the pelvic floor are difficult to study. The routine use of episiotomy for many years in order to prevent PFD is not recommended anymore; episiotomy should be used in selected cases, and the mediolateral procedures should be used if needed.

Verification of the Chromosome Region 9q21 Association with Pelvic Organ Prolapse Using RegulomeDB Annotations

Pelvic organ prolapse (POP) is a common highly disabling disorder with a large hereditary component. It is characterized by a loss of pelvic floor support that leads to the herniation of the uterus in or outside the vagina. Genome-wide linkage studies have shown an evidence of POP association with the region 9q21 and six other loci in European pedigrees. The aim of our study was to test the above associations in a case-control study in Russian population. Twelve SNPs including SNPs cited in the above studies and those selected using the RegulomeDB annotations for the region 9q21 were genotyped in 210 patients with POP (stages III-IV) and 292 controls with no even minimal POP. Genotyping was performed using the polymerase chain reaction with confronting two-pair primers (PCR–CTPP). Association analyses were conducted for individual SNPs, 9q21 haplotypes, and SNP-SNP interactions. SNP rs12237222 with the highest RegulomeDB score 1a appeared to be the key SNP in haplotypes associated with POP. Other RegulomeDB Category 1 SNPs, rs12551710 and rs2236479 (scores 1d and 1f, resp.), exhibited epistatic effects. In this study, we verified the region 9q21 association with POP in Russians, using RegulomeDB annotations.
