Abstract
Metabolic syndrome (MetS) is defined by a group of cardiovascular risk factors, including impaired glucose tolerance, central obesity, hypertension, and dyslipidemia. Overactive bladder (OAB) syndrome consists of symptoms such as urinary urgency, frequency, and nocturia with or without urge incontinence. The high prevalences of metabolic syndrome (MetS) and overactive bladder (OAB) worldwide affect quality of life and cause profound negative impacts on the social economy. Accumulated evidence suggests that MetS might contribute to the underlying mechanisms for developing OAB, and MetS-associated OAB could be a subtype of OAB. However, how could these two syndromes interact with each other? Based on results of animal studies and observations in epidemiological studies, we summarized the common pathophysiologies existing between MetS and OAB, including autonomic and peripheral neuropathies, chronic ischemia, proinflammatory status, dysregulation of nutrient-sensing pathways (e.g., insulin resistance at the bladder mucosa and excessive succinate intake), and the probable role of dysbiosis. Since the MetS-associated OAB is a subtype of OAB with distinctive pathophysiologies, the regular and non-specific medications, such as antimuscarinics, beta-3 agonist, and botulinum toxin injection, might lead to unsatisfying results. Understanding the pathophysiologies of MetS-associated OAB might benefit future studies exploring novel biomarkers for diagnosis and therapeutic targets on both MetS and OAB.

Abstract
Pelvic floor dysfunction is one of the most common disorders in women that is associated with social and economic consequences. In general, this disorder imposes direct and indirect costs on the economy of various societies. This review aimed to investigate pelvic floor dysfunction in women with polycystic ovary syndrome (PCOS). In this narrative review, the published articles on pelvic floor dysfunction were examined in PubMed, Scopus, Web of Sciences and Google Scholar. We searched for terms related to polycystic ovary syndrome and pelvic floor dysfunction. Inclusion criteria of this research were observational, experimental, and review studies. In this investigation, the complications associated with polycystic ovary syndrome were examined as risk factors for pelvic floor dysfunction. In this narrative review, we discuss about changes in hormone levels, obesity and overweight, hormonal medications and complications such as diabetes and metabolic disorders and obstetric complications of PCOS can be involved in the pathophysiology of pelvic floor dysfunctions, including stress urinary incontinence and pelvic organ prolapse in women with PCOS. This review highlights knowledge gaps about protective effect of hyperandrogenism on pelvic floor dysfunction as well as destructive effect of metabolic changes on pelvic floor dysfunction in women with PCOS. Further cohort and prospective studies are recommended in women with PCOS to investigate the concept of pelvic organ dysfunction in these women.

Abstract
Urinary tract infection (UTI) is caused principally by ascending Escherichia coli infection via an intestine-stool-urethra route. Recent studies found that the strains of E. coli causing UTIs, called extra-intestinal pathogenic E. coli (ExPEC), were distinct from the intestinal pathogenic strains and normal commensal strains. Further analysis found the meat including poultry and pork is the major reservoir for ExPECs. Vegetarians avoid meat and should theoretically have less exposure to ExPEC. However, no study thus far has examined whether vegetarian diets reduce the risk of UTI. Our aim was to examine the association between vegetarian diet and UTI risk in a Taiwanese Buddhist population. We prospectively followed 9724 Buddhists free of UTI from 2005 to 2014. During the 10-year follow-up, 661 incident UTI cases were confirmed. Diet was assessed through a food frequency questionnaire. Cox regression was used to evaluate the prospective association between a vegetarian diet on risk of UTI while adjusting for age, sex, educational level, alcohol-drinking, smoking, hypertension, diabetes mellitus, hyperlipidemia, and disease conditions predisposing to UTIs. Overall, vegetarian diet was associated with 16% lower hazards (hazard ratio [HR]: 0.84, 95% confidence interval [CI]: 0.71-0.99). In subgroup analysis, the protective association between vegetarian diet and UTI is observed mainly in the female (HR: 0.82, 95% CI: 0.69-0.99), never smokers (HR: 0.80, 95% CI: 0.67-0.95), and for uncomplicated UTI (HR: 0.81, 95% CI: 0.68-0.98).

Abstract
Objective: The purpose of this study was to investigate the prevalence and severity of the condition of lower urinary tract symptoms in Pakistani men, determine its predictors and assess its impact on the quality of life. Methods: A cross-sectional, population-based study was conducted among men aged 30 years and over in three districts of Punjab province, Pakistan. The modified Urdu version of the International Prostate Symptom Score was used to assess the prevalence and severity of lower urinary tract symptoms. Individuals with total symptom score ⩾8 were considered as having lower urinary tract symptoms. The data were analysed using SPSS version 22. The chi-square test and Mann-Whitney U test were used to assess the difference among categorical and continuous variables, respectively. Moreover, binary logistic regressions were performed to determine the predictors of lower urinary tract symptoms. Results: The overall prevalence of lower urinary tract symptoms in our sample was 33.7%. The frequency of individuals having mild, moderate and severe lower urinary tract symptoms was 66.3, 30.3 and 3.4%, respectively. Storage symptoms were more common than voiding symptoms (35.6% vs 28.2%, respectively). Increasing age (one-decade interval age stratum), higher education levels, working status (currently not working), smoking, hypertension, diabetes and renal impairment were positive predictors of lower urinary tract symptoms. Moreover, the condition of lower urinary tract symptoms was associated with a significant reduction in an individual’s quality of life. Conclusion: Around one-third of adult Pakistani men suffer from clinically relevant urinary symptoms, with lower urinary tract symptoms sufferers having poor quality of life as compared to non-sufferers. We recommend that the aging population should be made aware of conventional measures to mitigate mild urinary symptoms affecting their routine activities. Level of evidence: 2c

Park IN, Kim TB. Second to fourth digit ratio and lung function (forced vital capacity): predictors of maximum urinary flow rate after holmium laser enucleation of the prostate. Andrology 2018; 7:172-177. [PMID: 30450730 DOI: 10.1111/andr.12564] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Revised: 09/28/2018] [Accepted: 10/18/2018] [Indexed: 11/28/2022]
Abstract
BACKGROUND Maximum urinary flow rate (Qmax) is usually increased after holmium laser enucleation of the prostate (HoLEP). However, improvements vary between patients and results regarding potential predictors of Qmax after HoLEP are inconsistent. Thus, we investigated pre-operative variables including second to fourth digit ratio (digit ratio) and pulmonary function test (PFT) findings as potential predictors of Qmax after HoLEP. METHODS One hundred and ninety-five consecutive patients with benign prostatic hyperplasia (BPH) who underwent HoLEP were enrolled. Before HoLEP, PFTs were performed and lengths of second and fourth digits of right hands were measured by a single investigator using a digital vernier caliper. To identify independent predictors of Qmax after HoLEP, univariate and multivariate analyses were performed using linear regression models. RESULTS Mean age and total prostate volume for all 195 study subjects were 69.4 years and 63.3 mL respectively. Mean pre-operative and post-operative Qmax values were 8.7 and 26.2 mL/sec respectively. Univariate analysis showed age (r = -0.181, p = 0.014), digit ratio (r = 0.213, p = 0.004), lung function (forced vital capacity (FVC): r = 0.218, p = 0.005; forced expiratory volume in 1 sec (FEV1): r = 0.166, p = 0.034), pre-operative Qmax (r = 0.264, p = 0.000), pre-operative voided volume (VV) (r = 0.158, p = 0.033), and post-operative VV (r = 0.311, p = 0.000) were associated with post-operative Qmax, whereas multivariate analysis showed that digit ratio (β = 0.285, p = 0.001), FVC (β = 0.340, p = 0.039), and post-operative VV (β = 0.301, p = 0.000) independently predicted post-operative Qmax. CONCLUSIONS The independent predictors of Qmax after HoLEP were digit ratio and lung function (FVC) as well as post-operative VV. This means that the higher a man's digit ratio and lung function (FVC), the higher his Qmax after HoLEP.

Abstract
The prevalence of Heart failure (HF) is expected to increase worldwide with the aging population trend. The numerous symptoms of and repeated hospitalizations for HF negatively affect the patient’s quality of life and increase the patient’s economic burden. Up to 50% of patients with HF suffer from urinary incontinence (UI) and an overactive bladder (OAB). However, there are limited data about the relationship between UI, OAB, and HF. The association between HF and urinary symptoms may be directly attributable to worsening HF pathophysiology. A comprehensive literature review was conducted for all publications between January 2000 and November 2017 using the PubMed, Embase, and Cochrane databases. HF represents a major and growing public health problem, with an increased risk of UI and an OAB as comorbidities. Possible effects of HF on urinary problems may be mediated by the prescription of medications for symptomatic relief. Although diuretics are typically used to relieve congestion, and angiotensin-converting enzyme inhibitors and angiotensin receptor blockers improve survival, these classes of drugs have been suggested to worsen urinary symptoms in the presence of HF. Further research is required to understand the impact of UI and an OAB on the HF illness trajectory.

Abstract
BACKGROUND Bladder health in women and girls is poorly understood, in part, due to absence of a definition for clinical or research purposes. This article describes the process used by a National Institutes of Health funded transdisciplinary research team (The Prevention of Lower Urinary Tract Symptoms [PLUS] Consortium) to develop a definition of bladder health. METHODS The PLUS Consortium identified currently accepted lower urinary tract symptoms (LUTS) and outlined elements of storage and emptying functions of the bladder. Consistent with the World Health Organization's definition of health, PLUS concluded that absence of LUTS was insufficient and emphasizes the bladder's ability to adapt to short-term physical, psychosocial, and environmental challenges for the final definition. Definitions for subjective experiences and objective measures of bladder dysfunction and health were drafted. An additional bioregulatory function to protect against infection, neoplasia, chemical, or biologic threats was proposed. RESULTS PLUS proposes that bladder health be defined as: "A complete state of physical, mental, and social well-being related to bladder function and not merely the absence of LUTS. Healthy bladder function permits daily activities, adapts to short-term physical or environmental stressors, and allows optimal well-being (e.g., travel, exercise, social, occupational, or other activities)." Definitions for each element of bladder function are reported with suggested subjective and objective measures. CONCLUSIONS PLUS used a comprehensive transdisciplinary process to develop a bladder health definition. This will inform instrument development for evaluation of bladder health promotion and prevention of LUTS in research and public health initiatives.

Abstract
OBJECTIVE To conduct a prospective study to examine whether there are pretreatment and post-treatment disparities in urinary, sexual, and bowel quality of life (QOL) by race or ethnicity, education, or income in men with clinically localized prostate cancer (PCa.) METHODS: Participants (N = 1508; 81% white; 12% black; 7% Hispanic; 50% surgery; 27% radiotherapy; 23% active surveillance) completed the Expanded Prostate Cancer Index Composite measure of PCa-specific QOL prior to treatment, 6 weeks, 6, 12, 18, and 24 months after treatment. We analyzed pretreatment differences in QOL with multivariable linear regression and post-treatment differences with generalized estimating equation models. RESULTS Blacks and Hispanics (compared with whites) and men with lower income had worse pretreatment urinary function; poorer and less educated men had worse pretreatment sexual function (P < .05). In adjusted models, among men treated surgically, blacks and Hispanics had worse bowel function compared with whites, and men with lower income experienced more sexual bother and slower recovery in urinary function. Not all racial or ethnic differences favored whites; blacks had higher sexual function than whites prior to surgery and improved faster after surgery. Blacks receiving radiotherapy had lower post-treatment bowel bother than whites (P < .05). CONCLUSION Controlling for baseline QOL, there were some post-treatment disparities in urinary and sexual QOL that suggest the need to investigate whether treatment quality and access to follow-up care is equitable. However, survivorship disparities may, to a greater extent, reflect disadvantages in baseline health that exacerbate QOL issues after treatment.
