Project description:PurposeUrinary incontinence and fecal incontinence are common disorders in women that negatively impact quality of life. In addition to known health and lifestyle risk factors, genetics may have a role in continence. Identification of genetic variants associated with urinary incontinence and fecal incontinence could result in a better understanding of etiologic pathways, and new interventions and treatments.Materials and methodsWe previously generated genome-wide single nucleotide polymorphism data from Nurses' Health Studies participants. The participants provided longitudinal urinary incontinence and fecal incontinence information via questionnaires. Cases of urinary incontinence (6,120) had at least weekly urinary incontinence reported on a majority of questionnaires (3 or 4 across 12 to 16 years) while controls (4,811) consistently had little to no urinary incontinence reported. We classified cases of urinary incontinence in women into stress (1,809), urgency (1,942) and mixed (2,036) subtypes. Cases of fecal incontinence (4,247) had at least monthly fecal incontinence reported on a majority of questionnaires while controls (11,634) consistently had no fecal incontinence reported. We performed a genome-wide association study for each incontinence outcome.ResultsWe identified 8 single nucleotide polymorphisms significantly associated (p <5×10-8) with urinary incontinence located in 2 loci, chromosomes 8q23.3 and 1p32.2. There were no genome-wide significant findings for the urinary incontinence subtype analyses. However, the significant associations for overall urinary incontinence were stronger for the urgency and mixed subtypes than for stress. While no single nucleotide polymorphism reached genome-wide significance for fecal incontinence, 4 single nucleotide polymorphisms had p <10-6.ConclusionsFew studies have collected genetic data and detailed urinary incontinence and fecal incontinence information. This genome-wide association study provides initial evidence of genetic associations for urinary incontinence and merits further research to replicate our findings and identify additional risk variants.

Project description:Introduction and hypothesisThis study's aims were to detect and quantify bacterial DNA in the urine of randomized trial participants about to undergo treatment for urinary urgency incontinence (UUI) without clinical evidence of urinary tract infection (UTI) and to determine if the presence of bacterial DNA in baseline urine relates to either baseline urinary symptoms or UTI risk after urinary tract instrumentation.MethodsWomen without clinical evidence of baseline UTI were randomized to cystoscopic onabotulinum toxin A injection and oral placebo medication versus cystoscopic placebo injection and active oral medication. Bacterial DNA in participants' catheterized urine was measured by quantitative polymerase chain reaction (qPCR).ResultsBacterial DNA was detected in the urine of 38.7 % of participants (60 out of 155). In these 60 qPCR-positive participants, baseline daily UUI episodes were greater than in the 95 qPCR-negative participants (5.71 [±2.60] vs 4.72 [±2.86], p = 0.004). Neither symptom severity by questionnaire nor treatment outcome was associated with qPCR status or with qPCR level in qPCR-positive subjects. In contrast, the presence of urinary bacterial DNA was associated with UTI risk: only 10 % of the qPCR-positive women developed a UTI post-treatment, while 24 % of the qPCR-negative women did so. The median qPCR level for qPCR-positive samples did not differ significantly by UTI status (UTI 2.58 × 10(5) vs no UTI 1.35 × 10(5) copies/mL, p = 0.6).ConclusionsThese results may indicate a urinary bacterial contribution to both baseline UUI and the risk of post-treatment UTI.

Project description:Urinary incontinence in women is a common problem. With increasing age its prevalence and severity of its manifestations increase. Among nursing home residents the frequency is between 43 and 77 %, 6 to 10 % of all admissions to nursing homes are due to urinary incontinence. The risk for urinary incontinence among women with cognitive deficits is 1.5- to 3.4-fold higher than for women without mental disorders. The most common form is stress incontinence (50 %), followed by mixed stress-urge incontinence (40 %) and purely urge incontinence (OAB = overactive bladder, 20 %). With regard to its cause, the latter remains unclarified in about 80 % of the cases. It is often difficult to treat. There are also cases in which urge incontinence is related to traumatic events. In such cases behavioural and psychotherapeutic options may be helpful. Almost inevitably every form of incontinence has psychological consequences: shame and insecurity are often results of uncontrolled loss of urine. Among others, in the long term, they lead to the avoidance of social contacts and possibly to depression and isolation. Consideration of the psychosomatics is important in the therapy for female urinary incontinence from three points of view: 1) the efficacy of treatment is better suited to the patient, 2) the treatment costs are lower, 3) the professional satisfaction of the responsible physician increases.

Project description:We identify genetic variants associated with urgency urinary incontinence in postmenopausal women.A 2-stage genome-wide association analysis was conducted to identify variants associated with urgency urinary incontinence. The WHI GARNET substudy with 4,894 genotyped post-reproductive white women was randomly split into independent discovery and replication cohorts. Genome-wide imputation was performed using IMPUTE2 with the 1000 Genomes ALL Phase I integrated variant set as a reference. Controls reported no urgency urinary incontinence at enrollment or followup. Cases reported monthly or greater urgency urinary incontinence and leaked sufficiently to wet/soak underpants/clothes. Logistic regression models were used to predict urgency urinary incontinence case vs control status based on genotype, assuming additive inheritance. Age, obesity, diabetes and depression were included in the models as covariates.Following quality control, 975,508 single nucleotide polymorphisms in 2,241 cases (discovery 1,102; replication 1,133) and 776 controls (discovery 405, replication 371) remained. Genotype imputation resulted in 9,077,347 single nucleotide polymorphisms and insertions/deletions with minor allele frequency greater than 0.01 available for analysis. Meta-analysis of the discovery and replication samples identified 6 loci on chromosomes 5, 10, 11, 12 and 18 associated with urgency urinary incontinence at p <10(-6). Of the loci 3 were within genes, the zinc finger protein 521 (ZFP521) gene on chromosome 18q11, the ADAMTS16 gene on chromosome 5p15 and the CIT gene on chromosome 12q24. The other 3 loci were intergenic.Although environmental factors also likely contribute, this first exploratory genome-wide association study for urgency urinary incontinence suggests that genetic variants in the ZFP521, CIT and ADAMTS16 genes might account for some of the observed heritability of the condition.

Project description:BackgroundFemale urinary microbiota are associated with urgency urinary incontinence and response to medication. The urinary microbiota of women with stress urinary incontinence has not been described.ObjectiveWe sought to study the cross-sectional relationships between urinary microbiota features and demographic and clinical characteristics of women undergoing stress urinary incontinence surgery.Study designPreoperative urine specimens were collected from women without urinary tract infection and were available from 197 women (174 voided, 23 catheterized) enrolled in a multicenter prospective randomized trial, the Value of Urodynamic Evaluation study. Demographic and clinical variables were obtained including stress and urgency urinary incontinence symptoms, menopausal status, and hormone use. The bacterial composition of the urine was qualitatively assessed by sequencing the bacterial 16S ribosomal RNA gene. Phylogenetic relatedness and microbial alpha diversity were compared to demographics and symptoms using generalized estimating equation models.ResultsThe majority of 197 urine samples (86%) had detectable bacterial DNA. Bacterial diversity was significantly associated with higher body mass index (P = .02); increased Medical, Epidemiologic, and Social Aspects of Aging urge index score (P = .04); and hormonal status (P < .001). No associations were detected with stress urinary incontinence symptoms. Increased diversity was also associated with a concomitant lower frequency of Lactobacillus in hormone-negative women.ConclusionWomen undergoing stress urinary incontinence surgery have detectable urinary microbiota. This cross-sectional analysis revealed that increased diversity of the microbiota was associated with urgency urinary incontinence symptoms, hormonal status, and body mass index. In contrast, the female urinary microbiota were not associated with stress urinary incontinence symptoms.

Project description:BackgroundUrinary incontinence (UI) is prevalent in women and has been associated with decreased quality of life and institutionalization. Despite this, and the fact that several treatment options exist, few women discuss UI with clinicians. The aim of this study was to examine the proportion of middle aged and older women with urinary incontinence who have discussed UI with clinicians, focusing on female health professionals as a way to examine this question outside of issues of health care access.MethodsData are from the Nurses Health Studies (NHS), two ongoing observational, prospective, cohort studies. The surveys collected detailed information about UI, including frequency, amount and type. Women were also asked if they had discussed UI with a clinician. We used multivariable-adjusted logistic regression to estimate odds ratios (OR) of participants reporting discussion about UI.Results94,692 women with UI aged 49-91 years old were included in this study. Of these, 34% reported that they had discussed their incontinence with a clinician. Women with daily UI had 4.4 times greater odds of discussing it with clinicians when compared to those with monthly UI (OR = 4.36, 95% confidence interval [CI] 4.06-4.69). When controlling for severity of symptoms, the oldest women, greater than eighty years, were 20% less likely to have discussed UI with their clinician, compared to the youngest women (OR = 0.81, 95% CI 0.73-0.89).ConclusionsA minority of women with UI, even among health professionals, discuss their symptoms with clinicians. Oldest women were the least likely to discuss their UI with a provider.

Project description:INTRODUCTION AND HYPOTHESIS:To compare fecal incontinence (FI) and urinary incontinence (UI) disclosure in women with dual incontinence (DI), and to assess UI disclosure in DI subjects compared with women with UI alone. We hypothesized that women with DI would be less likely to disclose FI in comparison to UI and as likely to disclose UI as women with UI alone. METHODS:We performed a retrospective chart review of new patient visits to an academic urogynecology clinic from 2007 to 2011. Clinical records were reviewed; demographic data and responses to the Incontinence Severity Index (ISI) and Wexner scales were recorded. Patients' written responses to the ISI and Wexner were compared with the diagnoses obtained from the oral history by the physician. RESULTS:Of 1,899 women in the database, 557 women were diagnosed with DI and 447 women were diagnosed with UI alone. Women with DI were less likely to orally disclose FI than UI (135 out of 557 [23 %], vs 485 out of 557 [87 %], p?<?0.001), but were as likely as women with UI alone to disclose UI (385 out of 447 [86 %] vs 485 out of 557 [87 %], p?=?0.66). In the multivariate analysis, DI subjects had greater odds of disclosing FI to their physicians if they had private insurance (OR 1.9, 95 %CI 1.2, 3.0) or Wexner score >7 (OR 9.0, 95 % CI 5.4,14.8) and lower ISI score (OR 1.5, CI 1.4, 1.6). CONCLUSIONS:Women with DI were less likely to report FI in comparison to UI. Patients were more likely to orally report FI when the symptoms were severe.

Project description:BackgroundDietary nutrient intake contributes to urination; however, the association between dietary nutrient intake, especially that of fat, and urinary incontinence (UI) is not well understood. The most common types of UI include stress UI (SUI) and urgency UI (UUI).ObjectiveTo investigate the potential effect(s) of dietary fat intake on UI and explore its mechanism of action in relation to body mass index (BMI).MethodsA cross-sectional survey of data from 15,121 individuals (20-85 years of age) from the National Health and Nutrition Examination Survey (2001-2008), a random population-based sample, was performed. Data regarding dietary nutrient intake were collected through 24 h dietary recall interviews. UI and covariate data were collected through in-person interviews. UI was assessed according to the American Urological Association Symptom Index. The odds ratio (OR) for SUI and UUI were calculated using multivariate logistic regression analysis. The mediation effect was estimated using observational mediation analysis.ResultsHigher total fat intake was positively associated with increased odds for developing UI (OR 1.44 [95% confidence interval (CI) 1.08-1.93]). Females who consumed more saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA) were more likely to develop SUI. BMI partially explained the association between total fat, SFA, MUFA, and PUFA and SUI; the proportions of the mediation effect of BMI were 14.7%, 13.0%, 18.7%, and 16.3%, respectively.ConclusionsResults of this study emphasize the key role of dietary fat intake in the prevalence of UI. Higher fat intake was positively associated with UI and BMI partially mediated the effect of fat intake on SUI.

Project description:BackgroundUrinary incontinence (UI) can negatively affect a woman's quality of life, participation in sport and athletic performance. The objectives of this study were to determine the prevalence of UI in competitive women powerlifters; identify possible risk factors and activities likely to provoke UI; and establish self-care practices.MethodsThis international cross-sectional study was conducted using an online survey completed by 480 competitive women powerlifters aged between 20 and 71 years. The Incontinence Severity Index (ISI) was used to determine the severity of UI.ResultsWe found that 43.9% of women had experienced UI within the three months prior to this study. The deadlift was the most likely, and the bench-press the least likely exercise to provoke UI. ISI scores were positively correlated with parity (τ = 0.227, p < 0.001), age (τ = 0.179, p < 0.001), competition total (τ = 0.105, p = 0.002) and body mass index score (τ = 0.089, p = 0.009). There was no significant correlation between ISI and years strength training (τ = - 0.052, p = 0.147) or years powerlifting (τ = 0.041, p = 0.275). There was a negative correlation between ISI score with having a pelvic floor assessment (η = 0.197), and the ability to correctly perform pelvic floor exercises (η = 0.172).ConclusionThe prevalence of UI in this cohort was at the upper limit experienced by women in the general population. Women who had undergone a pelvic floor examination or were confident in correctly performing pelvic floor exercises experienced less severe UI.
