Cumulative incidence of urinary incontinence and associated factors during pregnancy and after childbirth: a cohort study.

INTRODUCTION AND HYPOTHESIS: This study examined the associated factors (i.e., obstetric and maternal-newborn factors) related to cumulative incidence of urinary incontinence and changes in urinary incontinence during pregnancy and the first year postpartum. METHODS: This prospective, longitudinal, within-subject study included 501 women who completed the Incontinence Questionnaire-Urinary Incontinence Short Form during pre-pregnancy, early pregnancy, mid-pregnancy, and late pregnancy and at five time points during the first year postpartum. Data were analyzed by multivariate logistic regression, McNemar's and analysis of variance (ANOVA) tests. RESULTS: According to the multivariate analysis, the gestational week and number of previous vaginal deliveries increased the risk of cumulative incidence of urinary incontinence (CIUI) during pregnancy (both p < 0.05). Full-time employment, higher body mass index, vaginal delivery and UI during early pregnancy and mid-pregnancy increased the risk of CIUI during the first year postpartum (all p < 0.05). CIUI tended to increase throughout the entire pregnancy (p < 0.001) and decrease from 3 to 5 days to 6 months postpartum (p = 0.028). The prevalence rates of UI at all postpartum visits were lower than those during late pregnancy (p < 0.001-0.009) but higher than those during pre-pregnancy (p < 0.001). CONCLUSIONS: The results identified the change patterns in UI and the risk factors associated with CIUI during the entire pregnancy (i.e., gestational age and number of previous vaginal deliveries) and the first year postpartum (i.e., full-time work, higher body mass index, vaginal delivery and UI during early and mid-pregnancy). Appropriate counseling should be provided to women preparing for pregnancy and during the prenatal and postpartum periods.

Clinical outcome and urodynamic changes of tailored transvaginal mesh surgery for pelvic organ prolapse: A mid-term 40 Months follow-up.

PURPOSE: To evaluate the changes in clinical outcome and urodynamic parameters after tailored anterior transvaginal mesh (ATVM) surgeries in a mid-term follow-up. METHODS: Between November 2011 and December 2015, women with ≥stage II pelvic organ prolapse (POP) who underwent ATVM surgeries were retrospectively reviewed. The data-reviewing timeframe was until December 2021. Clinical and urodynamic diagnoses regarding urinary symptoms were evaluated before and after the operation. RESULTS: A total of 160 women were included. Stress urinary incontinence decreased significantly after the operation (99% (159/160) vs. 43% (68/160), p < 0.01), as well as the pad weight (20.5 ± 2.7 vs. 9.4 ± 2.0, p < 0.001) and diagnosis of urodynamic stress incontinence (83% (132/160) vs. 51% (82/160), p < 0.01). Overactive bladder syndrome increased significantly after the operation (18% (29/160) vs. 28% (45/160), p = 0.03), even though the objective parameters, such as first and strong desire to void, bladder oversensitivity, and detrusor overactivity, were all improved after the operation. The pad weight was mostly improved significantly within the first postoperative 2 years. Eighteen (11%) women had global recurrent POP, and only one (0.6%) woman had true recurrence of cystocele. Twenty-four (15%) women had mesh extrusion, and two-thirds of them could be managed in an office setting. CONCLUSION: In women with advanced cystocele, the ATVM surgery provides a favorable anatomic reduction outcome with an acceptable mesh extrusion rate. The ATVM provides an anti-incontinence effect, both in subjective symptoms and objective parameters, but this effect might decline after postoperative 2 years.

Ugonin J improves metabolic disorder and ameliorates nonalcoholic fatty liver disease by regulating the AMPK/AKT signaling pathway.

Closely associated with visceral obesity, hepatic steatosis resulting from non-alcoholic fatty liver disease (NAFLD) exacerbates insulin resistance. Developing effective drugs to treat NAFLD is imperative. Here, we investigated the pharmacological mechanism of ugonin J (UJ) in controlling metabolic disorder and ameliorating NAFLD pathophysiology in diet-induced obese mice. The effects of UJ were assessed in 5-week-old C57BL/6 J mice fed a high-fat diet (HFD) for 12 weeks. UJ treatment averted HFD-induced body weight gain by reducing fat deposition in adipose tissues and reduced HFD-induced hyperlipidemia and hepatic inflammation. UJ also improved HFD-induced glucose tolerance and insulin resistance. Moreover, the mode of action of UJ was analyzed in palmitate (PA)-induced steatotic human HuS-E/2 hepatocytes and in hyperglycemia-simulating rat BRIN-BD11 pancreatic ß cells. In PA-induced steatotic human hepatocytes, UJ treatment promoted lipid clearance via pAMPK, pACC and CPT-1 upregulation and SREBP-1c downregulation. Interestingly, UJ upregulated Akt activity in hepatocytes and increased insulin secretion from ß cells in acute insulin secretion tests. Taken together, UJ improved adipocyte hypertrophy, hyperinsulinemia, hyperglycemia, hyperlipidemia and fat deposition in livers. UJ also reduced fatty acid accumulation by modulating key metabolic regulators. Our findings demonstrated the therapeutic potential of UJ for the treatment of NAFLD and diet-induced metabolic disorders.

Risk factors for stress and urge urinary incontinence during pregnancy and the first year postpartum: a prospective longitudinal study.

INTRODUCTION AND HYPOTHESIS: We examined obstetric and maternal-newborn factors and UI history for stress urinary incontinence (UI) and urge UI during pregnancy and the first year postpartum. METHODS: This prospective cohort study included 1447 pregnant women who underwent prenatal examinations and completed an Incontinence Questionnaire-Urinary Incontinence Short Form before pregnancy, during early, mid- and late pregnancy, and at five visits during the first year postpartum. Data were analyzed using univariate/multivariate generalized estimating equation (GEE) logistic regression analyses. RESULTS: The prevalence rates of stress UI during late pregnancy (42.5%) and urge UI at 3-5 days postpartum (10.4%) were the highest throughout pregnancy and the first year postpartum. After adjusting for covariates, gestational age increased the risks of stress UI (p < 0.001) and urge UI (p = 0.003); stress UI during pre-pregnancy, number of previous vaginal deliveries and concurrent high body mass index (BMI) increased stress UI (all p < 0.05); urge UI during pre-pregnancy and full-time work increased urge UI (both p < 0.05) during pregnancy. During the postpartum period, vaginal delivery increased stress UI (p < 0.001) and urge UI (p = 0.041); stress UI during pre-pregnancy and pregnancy, women aged ≥ 30 years and vacuum extraction/forceps delivery increased stress UI (all p < 0.05). Urge UI during early, mid- and late pregnancy increased stress UI (all p < 0.05). CONCLUSIONS: Gestational age increased stress and urge UI, while previous vaginal deliveries and high BMI increased stress UI; full-time work increased urge UI during pregnancy. Vaginal delivery increased both UIs, and vacuum/forceps delivery and maternal age increased stress UI during postpartum.

Predictors of an improvement in the severity of concomitant urodynamic stress incontinence after transvaginal mesh surgery for pelvic organ prolapse.

BACKGROUND/PURPOSE: Factors affecting the anti-incontinence efficacy of a tailored anterior transvaginal mesh (ATVM) surgery are undetermined. Thus, our aim was to investigate predictors for anti-incontinence efficacy of this ATVM surgery. METHODS: Medical records of women with pelvic organ prolapse and concomitant evident or occult urodynamic stress incontinence, who underwent the ATVM surgery but without concomitant anti-incontinence surgery, were reviewed. RESULTS: A total of 134 women were reviewed, including those who underwent ATVM only (n = 45), ATVM and posterior transvaginal mesh surgery (n = 88), and ATVM with total vaginal hysterectomy (n = 1). Multivariable analysis revealed that stage of cystocele (coefficient = 56.4), functional profile length (cm, coefficient = 61.1) and the score of general health perceptions in the King's Health Questionnaire (coefficient = -3.3) were independent predictors of the percentage change in pad weight from baseline. Seven (5.2%) women were found to have recurrent or persistent stress urinary incontinence, and 6 of the above 7 women underwent transobturator mid-urethral sling procedure. Free of further anti-incontinence surgery probabilities were 94.7% and 89.2% at 3 and 6 years after surgery, respectively. Functional profile length (hazard ratio = 2.61) was also identified as a predictor for further anti-incontinence surgery. CONCLUSION: Lesser degree of cystocele, shorter functional profile length and poorer general health perceptions were predictors of greater anti-incontinence effect after the tailored ATVM surgery. Besides, longer functional profile length was also a predictor for further anti-incontinence surgery after the ATVM surgery.

Prevalence of detrusor underactivity and bladder outlet obstruction in women with cystocele and changes in voiding function after cystocele repair.

PURPOSE: To evaluate the prevalence of detrusor underactivity (DU) and bladder outlet obstruction (BOO) in women with high-grade cystocele and the impacts of cystocele repair. METHODS: Between November 2010 and September 2018, women with ≥stage II cystocele were included. DU (detrusor pressure at maximum flow rate (PdetQmax) < 20 cmH2O, maximum flow rate (Qmax) < 15 mL/s, and bladder voiding efficiency < 90%) and BOO (PdetQmax ≥ 40 cmH2O and Qmax < 12 mL/s) were diagnosed by urodynamic study (UDS). Women who underwent cystocele repair were further analyzed with preoperative and postoperative comparisons. RESULTS: A total of 623 women were included. Forty-four (7%) and 17 (3%) women were diagnosed with DU and BOO, respectively. Among the 314 operatively treated women, a significant increase in DU (7% vs. 15%, p = 0.0007), especially in those with stage III cystocele, and a slightly decreased rate of BOO were noted postoperatively. UDS revealed that the postvoid residual volume, functional profile length, maximum urethral closure pressure (MUCP), and pressure transmission ratio at the MUCP decreased significantly, as did the pad weight. Nearly all lower urinary tract symptoms (LUTS) improved significantly, except nocturnal enuresis. Among bladder diary parameters, nocturia episodes, daytime frequency, urgency episodes, and incontinence episodes decreased significantly after the operation. CONCLUSION: The prevalence rates of DU and BOO in women with high-grade cystocele were 7% and 3%, respectively. After cystocele repair, the rate of DU increased. Most LUTS improved subjectively on questionnaires and objectively on UDS and bladder diary parameters after operation.

Helminthostachys zeylanica alleviates hepatic steatosis and insulin resistance in diet-induced obese mice.

BACKGROUND: Obesity and its associated health conditions, type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD), are worldwide health problems. It has been shown that insulin resistance is associated with increased hepatic lipid and causes hepatic steatosis through a myriad of mechanisms, including inflammatory signaling. METHODS: Helminthostachys zeylanica (HZ) is used widely as a common herbal medicine to relieve fever symptoms and inflammatory diseases in Asia. In the present study, we evaluated whether HZ has therapeutic effects on obesity, NAFLD and insulin resistance. The protective effects of HZ extract were examined using free fatty acid-induced steatosis in human HuS-E/2 cells and a high-fat diet-induced NAFLD in mice. RESULTS: The major components of the HZ extract are ugonins J and K, confirmed by HPLC. Incubation of human hepatocytes, HuS-E/2 cells, with palmitate markedly increased lipid accumulation and treatment with the HZ extract significantly decreased lipid deposition and facilitated AMPK and ACC activation. After 12 weeks of a high-fat diet with HZ extract treatment, the HFD mice were protected from hyperlipidemia and hyperglycemia. HZ extract prevented body weight gain, adipose tissue expansion and adipocyte hypertrophy in the HFD mice. In addition, fat accumulation was reduced in mice livers. Moreover, the insulin sensitivity-associated index, which evaluates insulin function, was also significantly restored. CONCLUSIONS: These results suggest that HZ has a promising pharmacological effect on high-fat diet-induced obesity, hepatic steatosis and insulin resistance, which may have the potential for clinical application.

Comparison of clinical outcomes between tailored transvaginal mesh surgery and native tissue repair for pelvic organ prolapse.

BACKGROUND/PURPOSE: The most suitable surgical technique for pelvic organ prolapse (POP) remains undetermined. The aim of this study was to compare clinical outcomes of the tailored transvaginal mesh (TVM) surgery and vaginal native tissue repair (NTR) surgery for POP. METHODS: Between November 2011 and August 2014, medical records of 339 women receiving POP surgeries were reviewed. RESULTS: Compared with the NTR group (n = 169), the use of TVM surgery (n = 170) was a predictor for longer operation time (coefficient = 25.2 min, P < 0.001) and larger blood loss (coefficient = 79.9 mL, P < 0.001) by multivariable analysis. However, a higher recurrence rate of cystoceles (log-rank test, P = 0.001) was found in the NTR group, compared with the TVM group; but not apical prolapse (P = 0.32) or rectocele (P = 0.45). Multivariable analysis revealed that the TVM surgery (hazard ratio = 0.24, 95% confidence interval = 0.09-0.64, P = 0.004) and old age (hazard ratio = 1.07, 95% confidence interval = 1.02-1.11, P = 0.005) were independent predictors for the recurrence of cystoceles. Based on the receiver operating characteristic curve (ROC) analysis, the cut-off age value was 64 years with an ROC area of 0.65. In women with intact uterus (n = 162), the recurrence rate of cystoceles was lower in the TVM group (log-rank test, P = 0.0001), compared with the NTR group. However, there was no between-group difference in the recurrence rate of cystoceles in women with prior or concomitant hysterectomy (n = 177, P = 0.17). CONCLUSION: In women with intact uterus, the TVM group has a lower recurrence rate of cystoceles than the NTR group. In addition, old age, especially more than 64 years old, is a risk factor for cystocele recurrence.

Clinical and urodynamic effects of baclofen in women with functional bladder outlet obstruction: Preliminary report.

AIM: To investigate the efficacy and urodynamic effects of baclofen in women with functional bladder outlet obstruction. METHODS: Between January 2011 and December 2012, women who underwent baclofen treatment for functional bladder outlet obstruction, defined as <15 mL/s maximum flow rate and >20 cmH2 O detrusor pressure at maximum flow rate, but without significant anatomic causes, were retrospectively reviewed. Urodynamic variables at baseline and after 12 weeks of treatment were compared. RESULTS: Twenty women with functional bladder outlet obstruction underwent 12 weeks of baclofen treatment (oral baclofen 5 mg, three times daily). All patients reported improvement in voiding dysfunction symptoms after treatment, and no significant adverse effects were found on review of medical records. All patients underwent urodynamic studies after 12 weeks' treatment. Voided volume, voiding efficiency and maximum flow rate at voiding cystometry were significantly improved (mean, 273 vs. 368 mL, P = 0.002; 62.8% vs. 73.6%, P <0.001, and 10.3 vs. 11.6 mL/s, P = 0.046; respectively). Moreover, baclofen did not affect continence function, as indicated by non-significant changes in the parameters of urethral pressure profiles. CONCLUSIONS: Oral baclofen can improve symptoms of voiding dysfunction, voided volume, voiding efficiency and maximum flow rate in women with functional bladder outlet obstruction. None of the patients experienced intolerable side-effects. Thus, oral baclofen may be used as an initial treatment for women with symptoms of voiding dysfunction.

Sex life and role identity in Taiwanese women during menopause: a qualitative study.

AIM: Our goal was to examine Taiwanese women's perspectives on the way menopause affected their sexual behaviour to gain an in-depth understanding of their experiences during this transition. BACKGROUND: Physical symptoms associated with menopause may affect women's sexual experiences. Little is known about how menopause-related changes in sexual behaviour may affect role identity of women living in a modernizing urban culture that is still strongly rooted in traditional beliefs and attitudes. DESIGN: This was a qualitative study involving face-to-face interviews using open-ended questions. METHODS: During 2011-2012, eighteen peri or postmenopausal women visiting a medical clinic for gynaecological examinations or treatment were interviewed about their sexual experiences. Responses were analysed for common themes. FINDINGS: Four themes were identified about the effects of menopause on women's sex life: (1) changes in physical responses during sex; (2) the acceptance/non-acceptance of the current situation; (3) sexual pressure related to their marital role; (4) efforts to improve sexual interest or activity. Menopause-related physical changes often (but not always) made sexual interactions difficult. But women's responses to the changes varied. Some used sexual discomfort as a reason to avoid sexual intercourse. Others sought to improve their sexual encounters through behavioural modifications or hormone therapy. CONCLUSIONS: Given the variety of reactions to the impact of menopause on sexual behaviour/relationships seen here, it is clear that health professionals need to assess of each woman's specific situation and be prepared to recommend a variety of behavioural or hormonal treatment options.

Sanguis draconis, a dragon's blood resin, attenuates high glucose-induced oxidative stress and endothelial dysfunction in human umbilical vein endothelial cells.

Hyperglycaemia, a characteristic feature of diabetes mellitus, induces endothelial dysfunction and vascular complications by limiting the proliferative potential of these cells. Here we aimed to investigate the effect of an ethanolic extract of Sanguis draconis (SD), a kind of dragon's blood resin that is obtained from Daemonorops draco (Palmae), on human umbilical vein endothelial cells (HUVEC) under high-glucose (HG) stimulation and its underlying mechanism. Concentration-dependent (0-50 µg/mL) assessment of cell viability showed that SD does not affect cell viability with a similar trend up to 48 h. Remarkably, SD (10-50 µg/mL) significantly attenuated the high-glucose (25 and 50 mM) induced cell toxicity in a concentration-dependent manner. SD inhibited high glucose-induced nitrite (NO) and lipid peroxidation (MDA) production and reactive oxygen species (ROS) formation in HUVEC. Western blot analysis revealed that SD treatments abolished HG-induced phosphorylation of extracellular signal-regulated kinase 1/2 (ERK 1/2), nuclear transcription factor, κB (NF-κB), VCAM-1, and E-selectin, and it also blocked the breakdown of PARP-116 kDa protein in a dose-dependent manner. Furthermore, we found that SD increased the expression of Bcl-2 and decreased Bax protein expression in HG-stimulated HUVEC. Thus, these results of this study demonstrate for the first time that SD inhibits glucose induced oxidative stress and vascular inflammation in HUVEC by inhibiting the ERK/NF-κB/PARP-1/Bax signaling cascade followed by suppressing the activation of VCAM-1 and E-selectin. These data suggest that SD may have a therapeutic potential in vascular inflammation due to the decreased levels of oxidative stress, apoptosis, and PARP-1 activation.

Factors associated with fecal incontinence in women with lower urinary tract symptoms.

AIM: The aim of this study was to identify the factors associated with fecal incontinence in female patients with lower urinary tract symptoms. MATERIAL AND METHODS: Data regarding clinical and urodynamic parameters and history of fecal incontinence of 1334 women with lower urinary tract symptoms who had previously undergone urodynamic evaluation were collected and subjected to univariate, multivariate, and receiver-operator characteristic curve analysis to identify significant associations between these parameters and fecal incontinence. RESULTS: Multivariate analysis identified age (odds ratio [OR]=1.03, 95% confidence interval [CI]=1.01-1.05, P=0.005), presence of diabetes (OR=2.10, 95%CI=1.22-3.61, P=0.007), presence of urodynamic stress incontinence (OR=1.90, 95%CI=1.24-2.91, P=0.003), pad weight (OR=1.01, 95%CI=1.00-1.01, P=0.04), and detrusor pressure at maximum flow (OR=1.02, 95%CI=1.01-1.03, P=0.003) as independent risk factors for fecal incontinence. Receiver-operator characteristic curve analysis identified age≥55years, detrusor pressure at maximum flow≥35 cmH(2) O, and pad weight≥15g as having positive predictive values of 11.4%, 11.5%, and 12.4%, respectively, thus indicating that they are the most predictive values in concomitant fecal incontinence. CONCLUSIONS: Detrusor pressure at maximum flow and pad weight may be associated with fecal incontinence in female patients with lower urinary tract symptoms, but require confirmation as indicators by further study before their use as screening tools.

The role of cyclooxygenase-derived oxidative stress in surgically induced lymphedema in a mouse tail model.

CONTEXT: Oxidative stress may contribute to lymphedema and subsequent tissue damage. However, the causal role of oxidative stress in lymphedema remains unclear. OBJECTIVE: We attempted to detect and identify the free radicals formed in lymphedema fluid and assessed the protective mechanisms and effects of specific enzyme inhibitors and natural antioxidants. MATERIALS AND METHODS: To study the level of postsurgical oxidative stress with lymphedema in a mouse tail model, we used an electron spin resonance (ESR) method and an ascorbyl radical's ESR spectrum as an oxidative stress biomarker. The drug-treatment group received an i.p. injection with indomethacin (2 mg/kg), baicalein (15 mg/kg), MK-886 (3 mg/kg), zileuton (6.25 mg/kg), diphenyleneiodonium (DPI; 1 mg/kg), sulforaphane (30 mg/kg), oryzanol (30 mg/kg) or sesamol (30 mg/kg) once daily for 14 d from the day of operation. All animals were sacrificed on day 14. RESULTS: Administration of indomethacin, sulforaphane, oryzanol and sesamol significantly suppressed both the tail volume (56.9%, 77.8%, 72.2% and 38.1% inhibition, respectively, p < 0.01) and ascorbyl radical signals (31.4%, 54.5%, 79.3% and 57.1% inhibition, respectively, p < 0.01), compared with the control mice. No significant differences were found between any of the baicalein, MK-886, or zileuton groups compared with the control. DPI suppressed the tail volume (25.9% inhibition, p < 0.01) but not the ascorbyl radical signals. CONCLUSION: This study showed that COX-derived oxidative stress plays a major role in the pathological mechanisms of surgically induced lymphedema. Indomethacin, sulforaphane, oryzanol and sesamol exhibit potent protective properties against surgically induced lymphedema.

Changes in urodynamic parameters after tolterodine treatment for female overactive bladder syndrome with or without voiding dysfunction.

AIM: To investigate changes in urodynamic parameters after tolterodine treatment for female overactive bladder syndrome, especially in patients with voiding dysfunction. METHODS: Between January and December 2006, 44 patients were enrolled for six months of treatment with tolterodine. Pre-treatment and post-treatment urodynamic studies were scheduled for the enrolled patients. RESULTS: Among the remaining 33 patients (11 dropped out), bladder capacity (P < 0.001) and post-void residual urine (P = 0.009) increased, and functional urethral length (P = 0.049) and pad weight test (P = 0.03) decreased after treatment. Besides this, detrusor pressure at maximal urine flow, functional urethral length, maximal urethral pressure and maximal urethral closure pressure were less affected by tolterodine in patients with voiding dysfunction, compared to those without voiding dysfunction. CONCLUSIONS: Tolterodine treatment increased bladder capacity and decreased urine leakage; however, some urodynamic parameters in patients with voiding dysfunction were less affected by tolterodine treatment.

Comparisons of urodynamic effects, therapeutic efficacy and safety of solifenacin versus tolterodine for female overactive bladder syndrome.

AIM: To evaluate the urodynamic effects, therapeutic efficacy and safety of solifenacin versus tolterodine treatment for women with overactive bladder syndrome. METHODS: Patients were randomized to receive either solifenacin 5 mg or tolterodine ER 4 mg once a day for 12 weeks at each four-week visit in a post-marketing study. Only women (solifenacin [n = 26] vs. tolterodine [n = 22]) were included in this subgroup analysis. Adverse events and changes of urodynamic values and clinical data were compared between the solifenacin and tolterodine groups. RESULTS: The volume voided per micturition increased in the solifenacin group (n = 21) (P = 0.04). The strong desire to void and pad-test result improved in the tolterodine group (n = 21; P = 0.02 and 0.03, respectively). There were no between-group differences in changes of any urodynamic data, voiding diary values or adverse events after treatment; however, changes of heart rate differed between the two groups (P = 0.0004), especially at visit 2 (solifenacin vs. tolterodine, -4.3 vs. 3.8, P = 0.02) and visit 3 (-3.2 vs. 4.8, P = 0.03). CONCLUSIONS: Both solifenacin and tolterodine had similar urodynamic effects, therapeutic efficacy and adverse events in treating women with overactive bladder syndrome; however, tolterodine had a greater effect in increasing heart rate than solifenacin.

A Taiwanese version of the International Consultation on Incontinence Questionnaire--Urinary Incontinence Short Form for pregnant women: instrument validation.

AIM: To translate the International Consultation on Incontinence Questionnaire--Urinary Incontinence Short Form (ICIQ-UI SF) from English to Taiwanese and to evaluate its reliability and validity for pregnant Taiwanese women. BACKGROUND: Urinary incontinence in pregnant women has been little investigated in Taiwan. A validated assessment instrument for urinary incontinence is needed for pregnant Taiwanese women. DESIGN: A non-experimental design was used to test the psychometric properties of the Taiwanese version of the ICIQ-UI SF. METHOD: The internal consistency reliability and construct validity of the Taiwanese version of the ICIQ-UI SF for pregnant women were evaluated in a random sample of 121 pregnant women at a medical center in Taiwan. Test-retest reliability was assessed for a sample of 55 pregnant women who completed this version at two time points in four weeks. Construct validity was verified with three questions and seven urinary-leakage situations by factor analysis. RESULTS: The Taiwanese version of the ICIQ-UI SF showed adequate test-retest reliability in pregnant Taiwanese women. The Pearson's correlation coefficient of the total score was 0.75, kappa statistics showed excellent or good reproducibility for most items and McNemar's test confirmed that there was no significant difference in the test-retest pair for each item of the scale. The internal consistency reliability of the scale was good, with Cronbach's α = 0.80. Three factors were extracted and identified with an eigenvalue ≥ 1.04, explaining 65.64% the total variance. The first, second and third factors were 'symptom and quality of life', 'stress incontinence or other types' and 'urge or overflow incontinence'. CONCLUSIONS: The results provide evidence of the validity and reliability of the psychometric properties of the Taiwanese version of the ICIQ-UI SF for pregnant women. RELEVANCE TO CLINICAL PRACTICE: This questionnaire is a suitable instrument for evaluating urinary incontinence in pregnant Taiwanese women.

Sexual function in women 3 days and 6 weeks after childbirth: a prospective longitudinal study using the Taiwan version of the Female Sexual Function Index.

INTRODUCTION: Childbirth impacts sexual function in women, but few reports have addressed sexual function shortly after childbirth. AIM: Using the Taiwan version of the Female Sexual Function Index (FSFIT), this study aimed to describe women's sexual function and to examine differences between groups in sexual function shortly after delivery. METHODS: A prospective longitudinal investigation was performed in women who completed the FSFIT, a numeric analog scale, the Taiwan version of the Center for Epidemiologic Studies Depression Scale (CES-D), and a demographic questionnaire in a Taiwanese medical center at 3 days and 6 weeks postpartum. MAIN OUTCOME MEASURES: Using a general linear model, differences were tested between groups, including those defined by delivery mode, type of feeding, depression score, pain score, and birth history. RESULTS: After adjusting for covariates, (i) significant differences in sexual function and desire were found between the vaginal delivery and Cesarean section groups at day 3 and week 6 postpartum (P = 0.0419 and <0.0001, respectively); (ii) differences in desire and satisfaction between the tubal ligation and not groups were significant at both time points (P = 0.0346 and 0.0338); (iii) differences in sexual function and sexual activity or intercourse between low and high CES-D scores were significant at 6 weeks postpartum (P = 0.0040 and 0.0043, respectively); and (iv) differences between pain level groups in sexual activity or intercourse and desire were significant at 6 weeks (P = 0.0493 and 0.0004). At 3 days postpartum, significant differences between educational level and ethnic groups were observed (P = 0.0002 and 0.0414). CONCLUSIONS: The results showed significant differences in sexual function shortly after delivery between groups based on delivery method, tubal ligation, depression, pain, ethnicity, and educational level. This information may help health professionals to be more aware of women's perception of sexuality and may foster sensitivity in assessing their sexual function after childbirth.

Solifenacin and tolterodine are equally effective in the treatment of overactive bladder symptoms.

BACKGROUND/PURPOSE: Various antimuscarinic agents have been developed for the treatment of overactive bladder (OAB). More data comparing these agents are still required. This study evaluated the efficacy and safety of solifenacin and tolterodine in Taiwanese patients with OAB symptoms. METHODS: This was a prospective, randomized, open-label study. A total of 75 patients (25 men and 50 women) with OAB symptoms were randomized to treatment with solifenacin (n = 39) or tolterodine (n = 36). Efficacy and safety variables were assessed and compared with the baseline and between the two groups. RESULTS: At week 12, solifenacin and tolterodine demonstrated equal efficacy in reducing the number of micturition (-2.56 ±3.31 vs. -2.44 ± 4.56, p = 0.58), urgency (-1.70 ± 3.07 vs. -1.15 ± 2.68, p =0.37) and incontinence (-2.79 ± 2.82 vs. -4.67 ± 9.29, p =0.28) episodes per 24 hours. There was no difference in improvement of the quality of life. The patient and physician assessments of treatment benefit were not statistically different for solifenacin and tolterodine (p = 0.23 and p = 0.52, respectively), with the majority showing benefits in both groups. The incidence of major adverse events, including dry mouth (18.0%vs. 8.3%, p = 0.31) and constipation (12.8%vs. 2.8%, p = 0.20) was not significantly different. Compared with baseline, the severity of dry mouth did not increase in either group. CONCLUSION: Both solifenacin and tolterodine are effective in treating key OAB symptoms, including urinary frequency, urgency and incontinence in the Taiwanese population. Both medications are comparably effective and safe, with the most common adverse effects being dry mouth and constipation.

Developing and validating a Taiwan version of the female sexual function index for pregnant women.

INTRODUCTION: Health professionals should pay more attention to the sexual concerns of pregnant women. An assessment instrument for female sexual function is needed for pregnant women in the Taiwanese population. AIM: To translate the Female Sexual Function Index (FSFI) from English to traditional Chinese, and to evaluate the reliability and validity of this new version for pregnant women. METHODS: Test-retest reliability of the newly developed Taiwan version of the FSFI for pregnant women was assessed in 55 pregnant women who completed this version of the questionnaire at two time points within 4 weeks. The internal consistency reliability and construct validity of the Taiwan version of the FSFI in a medical center in Taiwan were evaluated using a random sample of 121 pregnant women. MAIN OUTCOME MEASURES: Reliability was tested using Cronbach's alpha coefficient, Kappa statistics, McNemar's test, and Pearson's correlation coefficient. Construct validity was verified by factor analysis using the principal component option. RESULTS: The Taiwan version of the FSFI showed adequate test-retest reliability for pregnant women. The Pearson correlation coefficient of the total score was 0.69, Kappa statistics showed good reproducibility for most items, and McNemar's test confirmed that there were no significant differences in the test-retest pair for the 19 items of the scale. The internal consistency reliability of the scale was excellent (Cronbach's [alpha] = 0.96). Three factors were identified with eigenvalues > or =1.03, explaining 87.10% of the total variance. The first, second, and third factors were "coitus,""satisfaction," and "desire", accounting for 72.32%, 9.37%, and 5.42% of the variance, respectively. CONCLUSION: The results provided evidence of the validity and reliability of the Taiwan version of the FSFI for pregnant women. The questionnaire is a suitable instrument for measuring the sexual function of pregnant women and will be useful in research, teaching, and clinical practice.

The probability of re-treatment after discontinuation of a 3-month versus a 6-month course of solifenacin for female overactive bladder: A prospective randomized controlled study.

OBJECTIVES: The aim of this study is to compare the re-treatment probabilities after a 3-month versus a 6-month course of antimuscarinic treatment for women with overactive bladder syndrome (OAB). STUDY DESIGN: A prospective randomized controlled study. MAIN OUTCOME MEASURES: Between-group differences in the probability of re-treatment for OAB between the 3-month and 6-month groups. METHODS: Women with OAB were randomly allocated to receive solifenacin (5 mg per day) for a treatment interval of either 3 or 6 months. RESULTS: Ninety-one patients were treated in each group. The probability of re-treatment did not differ between the 3-month and 6-month groups (P = 0.11). Parity (hazard ratio = 1.81, P = 0.001), number of incontinence episodes (hazard ratio = 1.09, P = 0.008) and suboptimal response (hazard ratio = 3.56, P = 0.006) were independent predictors of re-treatment of OAB. Physical limitation, as indicated on the King's Health Questionnaire, was the only independent factor predicting completion of the scheduled treatment period (odds ratio = 1.01, P = 0.008). CONCLUSIONS: Prolonged antimuscarinic treatment does not decrease the need for re-treatment of OAB. Nonetheless, female patients with increased parity, more severe incontinence and a suboptimal response to antimuscarinic treatment are more likely to seek re-treatment of OAB due to recurrence of symptoms. In addition, patients with more serious physical limitation related to OAB are more likely to complete the scheduled treatment period. These findings could serve as a guide in clinical consultations regarding antimuscarinic treatment and if taken into consideration in future studies could lower the dropout rate.
