Is There Any Difference Between Depression and Anxiety in Overactive Bladder According to Sex? A Systematic Review and Meta-Analysis

Systematic review and meta-analysis on the association of metabolic syndrome in women with overactive bladder

AIMS

A systematic review and meta-analysis were performed to determine the association of metabolic syndrome (METS) in women with and without overactive bladder (OAB).

METHODS

PRISMA guidelines were followed and the protocol was registered at PROSPERO (CRD42024606398). We searched PubMed, Embase, Cochrane Library, and LILACS databases to obtain relevant articles for studies reporting METS outcomes related to OAB published through October 2024. A meta-analysis was performed of available studies using random effect models. Results are reported as mean difference (MD), standardized MD (SMD), or odds ratio (OR) and their 95% confidence interval (CI). Heterogeneity was described with the I2 statistic. The quality of studies was assessed using the Newcastle-Ottawa Scale.

RESULTS

Of the 108 non-duplicated retrieved citations, after successive selection, four case-control studies with low or moderate risk of bias reported information about the association of METS in women assessed with the 8-item OAB Symptom Bother Scale. OAB patients displayed higher body mass index (BMI, MD: 3.27, 95% CI: 2.12, 4.43), waist circumference (MD: 7.96, 95% CI: 4.41, 11.52), fasting blood glucose (SMD: 1.26, 95% CI: 0.18, 2.34), triglycerides (SMD: 0.24, 95% CI: 0.01, 0.47), and LDL-cholesterol (SMD: 0.30, 95%CI: 0.06, 0.54) levels. In addition to low HDL-cholesterol levels (SMD: -0.40, 95% CI: -0.74, -0.06) compared to the control group. There were no significant differences in circulating total cholesterol levels and rates of hypertension, hysterectomy, postmenopausal status, and constipation in women with and without OAB.

CONCLUSION

Women with OAB display associations with age, BMI, waist circumference, and METS factors.

The Orexin OX2 Receptor-Dependent Pathway Is Implicated in the Development of Overactive Bladder and Depression in Rats Exposed to Corticosterone

AIM

In the present study, we wanted to check whether TCS OX2 29 (TCS), a potent selective antagonist of OX2 receptors, would have positive effects in an animal model of detrusor overactivity co-existed with the depression-like state in Wistar male rats.

METHODS

The forced swim test with the measurement of spontaneous locomotor activity, conscious cystometry, determination of c-Fos expression in central micturition areas, and a set of biochemical analyses (with the use of urine, hippocampus, bladder urothelium, and detrusor muscle of tested animals) were carried out.

RESULTS

The outcomes showed that a 7-day administration of TCS (3 mg/kg/day, subcutaneously) normalizes the cystometric parameters corresponding to overactivity of the detrusor and reverses the pro-depressive response. Furthermore, the antagonism of OX2 receptors restored the abnormal levels of overactive bladder markers (i.e., ATP, CGRP, OCT3, TRPV1, ROCK1, and VAChT), diminished neuronal overactivity in central micturition areas (i.e., pontine micturition center, ventrolateral periaqueductal gray, and medial preoptic area) as well as restored the altered hippocampal levels of CRF, cytokines (IL-1β, IL-6, IL-10, and TNF-α), and growth factors (BDNF and NGF) that reflected biochemical disturbances detected in depressed people.

CONCLUSIONS

It seems that our findings open new perspectives regarding the implication of the orexin system in the functioning of the urinary bladder and in the pathophysiology of depression.

Bidirectional influence between benign prostatic hyperplasia, prostate cancer, and prostatitis and mental disorders: two-sample and multivariate mendelian randomization analyses

BACKGROUND

We aimed to use Mendelian randomization (MR) to determine the causality between fifteen major mental disorders (MDs) and benign prostatic hyperplasia (BPH), prostate cancer (PCa), and prostatitis.

METHODS

The main MR analysis was performed using the inverse variance-weighted (IVW) method.

RESULTS

The study found that insomnia (odds ratio [OR], 1.6190; p = .0017) was significantly associated with an increased risk of BPH, and mood disorders (OR, 1.1590; p = .0221) was nominally associated with an increased risk of BPH. Conversely, BPH was suggestively associated with a low epilepsy risk (OR, 0.9988; p = .0043), and was nominally associated with an increased risk of insomnia (OR, 1.0061; p = .0291). Furthermore, attention deficit hyperactivity disorder (ADHD) was suggestively associated with a low PCa risk (OR = 0.9474; p = .0058). However, no causal relationship was observed between PCa and MDs. Finally, anorexia nervosa (OR, 1.1686; p = .0248) and depression (OR, 336.5383; p = .0308) were nominally positively correlated with prostatitis. Prostatitis was suggestively associated with increased risk of ADHD (OR, 1.0868; p = .0413).

CONCLUSION

Our findings provide clinicians with a basis for developing programs to prevent or treat MDs and prostatic diseases.

Association of healthy eating index-2015 and overactive bladder: a cross-sectional study

Objective

The aim of this cross-sectional study was to investigate the association of HEI-2015 and overactive bladder (OAB) in a large population.

Methods

Data were retrieved from the National Health and Nutrition Examination Survey (NHANES) 2005-2020 datasets. Univariate and multivariate logistic regression were performed to evaluate the association between HEI-2015 and OAB. The restricted cubic spline (RCS) model was conducted to investigate the dose-response relationship.

Results

Totally, this study included 29,206 participants with 6,184 OAB patients among them. The higher continuous HEI-2015 value was independently associated with lower OAB incidence (OR: 0.87; 95%CI: 0.78, 0.98). Similarly, the highest quartile categorical HEI-2015 was significantly associated with a lower OAB odds (OR: 0.72; 95%CI: 0.52, 0.99) when compared with the lowest quartile. The RCS curve also showed a favorable non-linear dose-response relationship between HEI-2015 and OAB.

Conclusion

A higher HEI-2015 had a favorable association with OAB and there was a non-linear dose-response relationship between them. We suggest adherence to the United States diet recommendation as a potential behavioral prevention of OAB. Large-scale long term prospective cohort studies across various regions are needed to verify the findings of this paper.

Association between overactive bladder and depression in American adults: A cross-sectional study from NHANES 2005-2018

BACKGROUND AND AIM

Overactive bladder (OAB) and depression are both common disorders and there is research suggesting an association between the two, but there is a lack of studies with large samples. The aim of this study is to investigate the association between OAB and depressive symptoms.

METHODS

We used data from the National Health and Nutrition Examination Survey (NHANES) database for the period 2005 to 2018. OAB was characterized by the Overactive Bladder Symptom Score (OABSS, score > 3) and depression was diagnosed by the Patient Health Questionnaire (PHQ-9, score ≥ 10). There were three models employed in our analysis: (1) Crude model was unadjusted; (2) Model 1 was adjusted for age, sex, race/ethnicity, educational level, and marital status; (3) Model 2 was adjusted for factors in Model 1 plus the remained potential covariates. We used survey-weighted logistic regression models to assess the association between OAB and depression. Subsequently, subgroup analyses and smoothed curve analyses were used to evaluate the reliability of the findings.

RESULTS

Finally, a total of 6612 participants were included in our study, consisting of 1005 participants with diagnosis of OAB and 5607 participants without diagnosis of OAB. After adjusting for all covariates, there was a significant positive association between OAB and depression (OR: 2.89, 95 % CI: 1.91, 4.37). The severity of OAB was also positively associated with depression. Compared to participants without OAB, the fully adjusted ORs for depression were 2.76 (95 % CI: 1.64, 4.65) for those with mild OAB, 3.79 (95 % CI: 1.68, 8.55) for those with moderate OAB, and 5.21 (95 % CI: 1.39, 19.53) for those with severe OAB.

CONCLUSIONS

This study revealed a strong association between OAB and depression and a progressive increase in the risk of depression as the severity of OAB (mild, moderate, and severe) increased. Therefore, it is important for clinicians to recognize the assessment of OAB symptoms in patients who are at risk for or have developed depressive symptoms, as well as the mental health of patients with OAB.

An observational, patient-reported outcome study of sleep quality and depression among individuals with overactive bladder syndrome

INTRODUCTION

Overactive bladder (OAB) can adversely affect health-related quality-of-life (HRQoL) and adherence to treatments; however, the extent of their association is unknown. This study sought to characterize Sleep Disturbance, Depression, Fatigue, and patient-reported medication adherence among adults with OAB in the United States. MATERIALS AND METHODS: In this descriptive, observational study, patients completed patient-reported outcome (PRO) measures of urinary symptoms, anxiety, depression, fatigue, sleep quality, and medication adherence. PRO scores were compared across age, sex, body mass index, and sleep and antidepressant medication-taking subgroups. Exploratory analyses compared PRO scores between groups and estimated the effect size of differences.

RESULTS

Of 1013 patients contacted, 159 completed the assessments (female: 67.3%; ≥65 years of age: 53.5%; most severe OAB symptom: nocturia). Scale scores for Sleep Disturbance, Fatigue, and Depression were consistent with US population norms. No correlations of moderate or greater magnitude were observed between the severity of lower urinary tract symptoms and Sleep Disturbance, Fatigue, or Depression. When comparing individuals receiving antidepressants with those who were not, almost all outcomes including urinary symptoms, anxiety, and depression were significantly worse. Patients taking antidepressants also had poorer adherence to their OAB medications.

CONCLUSION

In this cohort of individuals with OAB, Sleep Disturbance, Fatigue, and Depression scores were in line with general population reference values; however, among the subgroups analyzed, patients on antidepressants had worse HRQoL and more substantial impacts on medication adherence, highlighting the importance of the assessment and management of depression in this population.

Sex differences in lower urinary tract symptoms of Korean workers: Prevalence, mental health, and associated factors

Objectives

Lower urinary tract symptoms (LUTS) in workers can aggravate mental health, lower quality of life, and decrease work productivity. We aimed to examine the prevalence of LUTS, sex-related differences in LUTS, mental health of workers with LUTS, and factors associated with LUTS in Korean workers.

Methods

This cross-sectional study included 192 workers from D city and the Gyeongbuk province of South Korea. LUTS were measured using self-reported questionnaires, and mental health was assessed for anxiety, depression, and perceived stress. Differences in characteristics between workers with and without LUTS were analyzed using the chi-square test or independent t-test. Multiple logistic regression analysis was performed to identify factors associated with LUTS.

Results

Urinary urgency (UU) was significantly more prevalent in men than in women; however, stress urinary incontinence (SUI) was more prevalent in women than in men. The average anxiety and perceived stress scores were significantly higher in men with UU than in men without UU. Men with hypertension or nocturia were more likely to have UU than those without hypertension or nocturia. The anxiety scores significantly increased the odds of UU in men. Advanced age significantly increased the odds of SUI in women. Blue-collar female workers were more likely to develop SUI than their white-collar counterparts.

Conclusions

Our study highlighted the prevalence and burden of LUTS among workers. Occupational health providers need to regularly assess workers' bladder storage problems and provide manageable interventions for UU in men and SUI in women.

A positive association between the prevalence of circadian syndrome and overactive bladder in United States adults

Objective

To explore the association between the prevalence of circadian syndrome (CircS) and overactive bladder (OAB).

Materials and methods

Cross-section analysis was based on the National Health and Nutrition Examination Survey 2005-2018. Data regarding OAB was collected from questionnaires. The association between the prevalence of CircS and OAB was elucidated using three multivariable logistic regression models. Stratified and interaction analyses were performed to find whether some factors can modify the association.

Results

Totally 8,033 males and 8,065 females were included. People with CircS had a significantly higher prevalence of OAB compared to the non-CircS group in the fully-adjusted model (OR = 1.238, 95%CI 1.080-1.419). A significant positive correlation between the number of CircS components and the prevalence of OAB was observed when the components were ≥ 6 (OR = 1.975, 95%CI 1.463-2.665). No significant interaction was seen in the three models.

Conclusion

There is a positive association between the prevalence of CircS and OAB. When the number of components is ≥6, the prevalence of OAB shows a strongly positive correlation with the number of CircS components.

The Impact of Caffeine Intake on Mental Health Symptoms in Postmenopausal Females with Overactive Bladder Symptoms: A Randomized, Double-Blind, Placebo-Controlled Trial

Background: Caffeine has been associated with a dose-dependent variety of mental health changes, which have been found to precede or be a complication of overactive bladder (OAB) symptoms after menopause. The current study examines the effects of low and moderate caffeine intake on anxiety, depression, sleep, and stress in postmenopausal females with OAB. Materials and Methods: Eighty-one females were randomized in a prospective, double-blind, placebo-controlled study. Participants were allocated to 200 mg/day caffeine, 400 mg/day caffeine, and placebo capsules for 1 week each in a crossover design and evaluated using validated mental health questionnaires. Symptoms during each treatment phase were measured using Beck Anxiety and Depression Inventory, Insomnia Severity Index, and Perceived Stress Scale. Linear regression models were used to examine the impact of low (200 mg/day) and moderate (400 mg/day) dose of caffeine and placebo on mental health. Results: Fifty-six female participants finished the study. The mean age was 69.2 years (58.0-84.0 years). Two females dropped out during the treatment phase with 400 mg/day caffeine intake due to side effects associated with headaches and nausea. Moderate dose of caffeine showed a small positive effect on mental health, specifically a decrease in anxiety during 7 days of exposure (p < 0.05). Conclusions: Moderate caffeine use may decrease anxiety in postmenopausal patients with underlying OAB, whereas depression, insomnia, and perceived stress were not affected by low-to-moderate caffeine intake. Our results support that counseling efforts on moderate caffeine consumption in postmenopausal patients underline that low-to moderate caffeine intake may be appropriate and possibly beneficial unless contraindicated due to other underlying conditions. Clinical Trials Registration: clinicaltrials.gov (NCT02180048).

Effects of mirabegron on depression, anxiety, learning and memory in mice

Mirabegron is the first b3-adrenoceptor agonist to enter clinical practice and has been approved for the treatment of symptoms of OAB. The aim of this study is to investigate whether the mirabegron has an effect on depression, anxiety, learning, and memory. We investigated the effects of mirabegron on depression, anxiety, learning and memory by using forced swimming test, elevated plus maze test, passive avoidance and Morris water maze in mice. Imipramine and mirabegron (3, 6 and 9 mg/kg) significantly reduced immobility time in forced swimming test. Diazepam and mirabegron (3, 6 and 9 mg/kg) significantly increased the time spent in open arms and the number of entries to the open arms in elevated plus maze test. Furthermore, cognitive performance impaired with scopolamine has been significantly improved with 9 mg/kg mirabegron. Mirabegron (6 and 9 mg/kg) significantly increased the time spent in the target quadrant in naive mice. While scopolamine significantly increased the swimming speed, mirabegron (9 mg/kg) significantly decreased the swimming speed in scopolamine-treated mice. Mirabegron might be clinically useful for the treatment of OAB in elderly patients that should use drugs against depression and anxiety, without disrupt learning and memory.

Validating 7-items Overactive Bladder Symptom Score (OABSS) through Arabic linguistic version

The scoring of the 7-item Overactive Bladder Symptom Score (OABSS) questionnaire is unusual because its scale varies with the same maximum and minimum scoring values and quantifies all aspects of OAB. The questionnaire also contains a graded response for urgency. The current study is mainly concerned with the development and validation of the OABSS questionnaire for Jordanian patients. The process of translating the English OABSS questionnaire into the Arabic language involved forward and backward translations. Afterward, a prospective study was conducted to validate the Arabic version of the OABSS questionnaire by examining 235 patients from the outpatient clinics of Karak Governorate Teaching Hospital. The Arabic OABSS questionnaire was completed by all the enrolled patients before and after three months of treatment with solifenacin 5 mg taken once daily. The study included 235 regular patients (152 females and 83 males) diagnosed with OAB in accordance with the definition of the International Continence Society (ICS). The results showed major and significant differences on all seven domains of the questions on the OABSS questionnaire before and after receiving treatment (p < 0.05). Confirmatory Factor Analysis was used to measure the reliability and the questionnaire was found to be highly reliable for the construct variables. The findings derived from the current study would be beneficial for local urologists and researchers, as the Arabic version of the OABSS questionnaire was proven to be a reliable instrument for use in the assessment of OAB. Future studies are needed to compare different translated questionnaires relating to OAB.Trial registration number: NCT04309890.

Sacral nerve stimulation for refractory OAB and idiopathic urinary retention: Can phenotyping improve the outcome for patients: ICI-RS 2019?

AIMS

Sacral nerve stimulation (SNS) is widely used to treat refractory idiopathic overactive bladder (OAB) and idiopathic urinary retention. However, clinical outcomes are variable and understanding predictive factors for success or side-effects would enable personalization of therapy and optimization of outcomes. At the International Consultation on Incontinence-Research Society meeting 2019, a Think Tank was convened to discuss how advances in the basic science study of SNS may be translatable into clinical practice to improve outcomes of patients undergoing SNS treatment.

METHODS

We conducted a literature review and expert consensus meeting focusing on current methods of phenotyping patients and specifically, how advances in basic science research of the mechanism of action of SNS can be translated into clinical practice to improve patient selection for therapy.

RESULTS

The terms "Idiopathic OAB" and "idiopathic urinary retention" encompass several underlying pathophysiological phenotypes. Commonly, phenotyping is based on clinical and urodynamic factors. Animal studies have demonstrated that high-frequency stimulation can produce rapid onset, reversible conduction block in peripheral nerves. Altering stimulation parameters may potentially enable personalization of therapy depending upon the clinical indication in the future. Similarly, advances in conditional and closed-loop stimulation may offer greater efficacy for certain patients. Phenotyping based on psychological comorbidity requires further study to potentially optimize patient selection for therapy.

CONCLUSIONS

Idiopathic OAB and idiopathic urinary retention are heterogenous conditions with multiple potential underlying phenotypes. Tailoring stimulation parameters to the needs of each individual according to phenotype could optimize outcomes. Assessing psychological comorbidity may improve patient selection. Areas for further research are proposed.

What is the Impact of Racial Disparities on Diagnosis and Receipt of Appropriate Mental Health Care Among Urology Patients?

Patients with chronic disease and mental illness are at higher risk of depression and suicide. Many who have been diagnosed with genitourinary cancers are at higher risk of suicide, even among those who have sought out mental health services. Under-represented populations (African-American, Hispanic, elderly, disabled) suffer disproportionately from a lack of mental health services. However, not much is reported on the interplay of mental health and genitourinary cancer in these populations. This review aims to identify the relevant literature and describe a path forward to address and alleviate this disparity. PATIENT SUMMARY: Patients with chronic disease and mental illness are at higher risk of depression and suicide. Little is known about the complex interplay between race and mental health in patients with urologic cancers and more research is needed.

Abnormal Brain Functional Connectivity Strength in the Overactive Bladder Syndrome: A Resting-State fMRI Study

OBJECTIVE

To investigate the whole-brain functional connectivity strength (FCS) of patients with the overactive bladder syndrome (OAB).

METHODS

This study investigates the changes of intrinsic whole brain functional connectivity pattern in OAB using FCS. We acquired resting-state fMRI data from 26 OAB patients and 28 healthy controls. FCS was used to compute the long-range and short-range FCS values for each voxel in the brain of each subject. The long or short-range FCS maps were compared between OAB patients and healthy controls. Pearson's correlation coefficients was also performed between abnormal FCS regions and clinical/psychometric scores in patients.

RESULTS

Compared with healthy control subjects, the OAB patients exhibited significantly decreased short-range FCS in the right medial superior frontal gyrus and bilateral anterior cingulate gyrus, and increased short-range FCS in the middle frontal gyrus, the precentral gyrus, and bilateral caudate nucleus. In addition, significantly decreased long-range FCS was found in bilateral middle cingulate gyrus and posterior cingulate gyrus. Furthermore, the abnormal FCS values in the right caudate nucleus showed significantly negative correlation with Self-Rating Depression Scale of OAB patients.

CONCLUSION

Patients with OAB have abnormal short-range and long-range FCS in brain regions associated with brain-bladder network. Our study provides new insights into the underlying brain network topology of OAB.

Are psychological comorbidities important in the aetiology of lower urinary tract dysfunction-ICI-RS 2018?

AIMS

To review studies on the comorbid psychological symptoms and disorders in patients with lower urinary tract disorders (LUTD) over the life-span, to analyse how they contribute toward the aetiology of LUTD and to discuss optimal service implementation.

MATERIALS AND METHODS

A review of relevant literature was conducted and presented during the ICI-RS meeting in 2018. Open questions and future directions were discussed.

RESULTS

On the basis of current research, there is overwhelming evidence in all age groups that psychological comorbidities are more common in patients with LUTD. Vice versa, patients with psychiatric disorders have higher rates of LUTD. The types of LUTDs and psychiatric disorders are heterogeneous. Complex aetiological models best explain specific associations of comorbidity. Irrespective of aetiology, it is advisable to address both urological and psychological issues in patients of all age groups with LUTD.

CONCLUSIONS

Psychological symptoms and disorders play a decisive role in the development of LUTD in all age groups and need to be considered in the assessment and treatment of LUTD.
