Depression is a major risk factor for the development of dementia in people with lower urinary tract symptoms: A nationwide population-based study

Loneliness, functional disability and lower urinary tract symptoms suggestive of benign prostatic hyperplasia in aging men: Insights from the China health and retirement longitudinal study

BACKGROUND

Research has demonstrated that social isolation and loneliness are linked to functional disability in older adults. With the intensification of global aging, functional disability and lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) have become common public health issues affecting elderly men.

METHODS

This study utilized data from the CHARLS database. The functional status of participants was evaluated through activities of daily living (ADL) and instrumental activities of daily living (IADL). Logistic regression analyses were employed to investigate variables associated with LUTS/BPH.

RESULTS

Univariate logistic regression revealed associations between loneliness (OR: 1.26; 95 % CI: 1.08-1.46) (excluding social isolation), ADL (OR: 2.17; 95 % CI: 1.86-2.52), IADL disability (OR: 1.37; 95 % CI: 1.16-1.60), and LUTS/BPH. Following rigorous adjustment for potential confounding factors, it was determined that ADL disability independently correlated with LUTS/BPH (OR: 1.92; 95 % CI: 1.17-3.17).

CONCLUSION

ADL disability is significantly linked to an elevated risk of LUTS/BPH in Chinese elderly men. These findings enhance our understanding of the relationship between functional status and LUTS/BPH.

Depression as a Risk Factor for Dementia: A Meta-Analysis

Dementia is a syndrome characterized by the deterioration of cognitive function beyond what is expected. The increased risk of developing this syndrome resulting from established modifiable risk factors, such as depressive episodes, is currently a subject of interest. The aim of this study was to review the scientific evidence that addresses the relationship between depression and dementia. A bibliographic search of the PubMed and PsycInfo databases for articles published over the past 20 years was conducted with the following medical subject heading terms: depression or depressive, dementia, and incidence or cohort studies. After articles meeting the inclusion criteria were selected, relevant moderating variables were grouped as sample characteristics, methodological characteristics, extrinsic characteristics, and outcome variables. The 26 selected studies resulted in a sample comprising 1,760,262 individuals. Statistical analysis revealed a pooled relative risk for the development of dementia of 1.82 (95% CI=1.62-2.06). The primary variables evaluated were the diagnostic methods for depression and dementia and the presence of depression. Other variables, such as mean age, methodological quality of each study, follow-up time, and publication year, were also evaluated. Age was statistically but not clinically significant. No relevant publication bias or alterations in the results were found when accounting for the quality of the studies. It is recommended that new moderating variables be evaluated or that existing variables be reformulated in future studies.

Lower Urinary Tract Symptoms in Depression: A Review

Lower Urinary Tract Symptoms (LUTS) are frequently present in the general population as patients age with approximately a third of individuals experiencing LUTS during their lifetime. LUTS can be further defined as having any of the following symptoms: urinary hesitancy, straining, nocturia, increased urination frequency, and dysuria. LUTS has the potential for patients to contribute their symptoms to what can normally occur as we age. This can lead to a decrease in patients seeking care and could negatively impact patients' health-related quality of life (HRQL). In conjunction with LUTS, we obtained from our analysis that LUTS and depression are closely related and worsening depressive symptoms may increase the severity of LUTS. We also discerned three categories of factors that can yield major depression namely adversity, internalizing, and externalizing factors. Within these categories, trauma, social support, genetic factors, and minimal education appeared to increase the risk of depression in patients. With the recent increase in mental health awareness and more access to mental health care amid the COVID-19 Pandemic, further screening, and collaboration between providers to treat both urological and psychiatric symptoms could improve patient outcomes. It is important for providers to have an increased understanding of the mental and physical impact both LUTS and depression can have on patients' wellbeing. This has the potential to help patients be more open about their symptoms with the aim of better addressing LUTS and depression to positively impact their HRQL.

Acupuncture for treating overactive bladder in adults

BACKGROUND

Overactive bladder is a common, long-term symptom complex, which includes frequency of micturition, urgency with or without associated incontinence and nocturia. Around 11% of the population have symptoms, with this figure increasing with age. Symptoms can be linked to social anxiety and adaptive behavioural change. The cost of treating overactive bladder is considerable, with current treatments varying in effectiveness and being associated with side effects. Acupuncture has been suggested as an alternative treatment.

OBJECTIVES

To assess the effects of acupuncture for treating overactive bladder in adults, and to summarise the principal findings of relevant economic evaluations.

SEARCH METHODS

We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (including In-Process, Epub Ahead of Print, Daily), ClinicalTrials.gov and WHO ICTRP (searched 14 May 2022). We also searched the Allied and Complementary Medicine database (AMED) and bibliographic databases where knowledge of the Chinese language was necessary: China National Knowledge Infrastructure (CNKI); Chinese Science and Technology Periodical Database (VIP) and WANFANG (China Online Journals), as well as the reference lists of relevant articles.  SELECTION CRITERIA: We included randomised controlled trials (RCTs), quasi-RCTs and cross-over RCTs assessing the effects of acupuncture for treating overactive bladder in adults.

DATA COLLECTION AND ANALYSIS

Four review authors formed pairs to assess study eligibility and extract data. Both pairs used Covidence software to perform screening and data extraction. We assessed risk of bias using Cochrane's risk of bias tool and assessed heterogeneity using the Chi2 testand I2 statistic generated within the meta-analyses. We used a fixed-effect model within the meta-analyses unless there was a moderate or high level of heterogeneity, where we employed a random-effects model. We used the GRADE approach to assess the certainty of evidence.

MAIN RESULTS

We included 15 studies involving 1395 participants in this review (14 RCTs and one quasi-RCT). All included studies raised some concerns regarding risk of bias. Blinding of participants to treatment group was only achieved in 20% of studies, we considered blinding of outcome assessors and allocation concealment to be low risk in only 25% of the studies, and random sequence generation to be either unclear or high risk in more than 50% of the studies. Acupuncture versus no treatment One study compared acupuncture to no treatment. The evidence is very uncertain regarding the effect of acupuncture compared to no treatment in curing or improving overactive bladder symptoms and on the number of minor adverse events (both very low-certainty evidence). The study report explicitly stated that no major adverse events occurred. The study did not report on the presence or absence of urinary urgency, episodes of urinary incontinence, daytime urinary frequency or episodes of nocturia. Acupuncture versus sham acupuncture Five studies compared acupuncture with sham acupuncture. The evidence is very uncertain about the effect of acupuncture on curing or improving overactive bladder symptoms compared to sham acupuncture (standardised mean difference (SMD) -0.36, 95% confidence interval (CI) -1.03 to 0.31; 3 studies; 151 participants; I2 = 65%; very low-certainty evidence). All five studies explicitly stated that there were no major adverse events observed during the study. Moderate-certainty evidence suggests that acupuncture probably makes no difference to the incidence of minor adverse events compared to sham acupuncture (risk ratio (RR) 1.28, 95% CI 0.30 to 5.36; 4 studies; 222 participants; I² = 0%). Only one small study reported data for the presence or absence of urgency and for episodes of nocturia. The evidence is of very low certainty for both of these outcomes and in both cases the lower confidence interval is implausible. Moderate-certainty evidence suggests there is probably little or no difference in episodes of urinary incontinence between acupuncture and sham acupuncture (mean difference (MD) 0.55, 95% CI -1.51 to 2.60; 2 studies; 121 participants; I2 = 57%). Two studies recorded data regarding daytime urinary frequency but we could not combine them in a meta-analysis due to differences in methodologies (very low-certainty evidence). Acupuncture versus medication Eleven studies compared acupuncture with medication. Low-certainty evidence suggests that acupuncture may slightly increase how many people's overactive bladder symptoms are cured or improved compared to medication (RR 1.25, 95% CI 1.10 to 1.43; 5 studies; 258 participants; I2 = 19%). Low-certainty evidence suggests that acupuncture may reduce the incidence of minor adverse events when compared to medication (RR 0.34, 95% CI 0.26 to 0.45; 8 studies; 1004 participants; I² = 51%). The evidence is uncertain regarding the effect of acupuncture on the presence or absence of urinary urgency (MD -0.40, 95% CI -0.56 to -0.24; 2 studies; 80 participants; I2 = 0%; very low-certainty evidence) and episodes of urinary incontinence (MD -0.33, 95% CI -2.75 to 2.09; 1 study; 20 participants; very low-certainty evidence) compared to medication. Low-certainty evidence suggests there may be little to no effect of acupuncture compared to medication in terms of daytime urinary frequency (MD 0.73, 95% CI -0.39 to 1.85; 4 studies; 360 participants; I2 = 28%). Acupuncture may slightly reduce the number of nocturia episodes compared to medication (MD -0.50, 95% CI -0.65 to -0.36; 2 studies; 80 participants; I2 = 0%, low-certainty evidence). There were no incidences of major adverse events in any of the included studies. However, major adverse events are rare in acupuncture trials and the numbers included in this review may be insufficient to detect these events.

AUTHORS' CONCLUSIONS

The evidence is very uncertain about the effect acupuncture has on cure or improvement of overactive bladder symptoms compared to no treatment. It is uncertain if there is any difference between acupuncture and sham acupuncture in cure or improvement of overactive bladder symptoms. This review provides low-certainty evidence that acupuncture may result in a slight increase in cure or improvement of overactive bladder symptoms when compared with medication and may reduce the incidence of minor adverse events. These conclusions must remain tentative until the completion of larger, higher-quality studies that use relevant, comparable outcomes. Timing and frequency of treatment, point selection, application and long-term follow-up are other areas relevant for research.

Depressive symptoms in individuals diagnosed with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) in middle-aged and older Chinese individuals: Results from the China Health and Retirement Longitudinal Study

OBJECTIVES

Male lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) is common and may increase the risk of depressive symptoms. This study aimed to investigate the associated factors of LUTS/BPH and its association with depressive symptoms in middle-aged and older Chinese men.

METHODS

This study used data from the 2015 China Health and Retirement Longitudinal Study (CHARLS). A total number of 8,586 men aged ≥45 years were included in this study. Participants answered positively to whether they have ever been diagnosed with a prostate illness (excluding prostatic cancer) were defined as LUTS/BPH individuals. Depressive symptoms were assessed using the 10-item Center for Epidemiological Studies Depression Scale (CESD-10). Multivariate logistic analyses were applied to explore the associated factors of LUTS/BPH, association between LUTS/BPH and depressive symptoms, and risk factors of depressive symptoms according to LUTS/BPH status.

RESULTS

The weighted overall prevalence of LUTS/BPH was 13.1% in Chinese men aged ≥45 years. The prevalence of depressive symptoms was 29.1% in LUTS/BPH individuals and 22.9% in non-LUTS/BPH individuals. Depressive symptoms and LUTS/BPH shared some same risk factors, which were education, living regions, annual household consumption, sleep duration and multimorbidity. The results from logistic models showed that education, sleep duration and multimorbidity were significantly and independently associated with depression of LUTS/BPH individuals (P<0.001).

CONCLUSIONS

Prevalence of depressive symptoms in LUTS/BPH population was higher than in non-LUTS/BPH population. Education, sleep duration and multimorbidity were associated with the onset of depressive symptoms in LUTS/BPH individuals (P<0.001).

The Impact of Illness Perceptions on Depressive Symptoms Among Benign Prostatic Hyperplasia Patients with Lower Urinary Tract Symptom

Objective

This study aimed at exploring whether illness perceptions may mediate the relationship between depressive symptoms and lower urinary tract symptoms (LUTS) among benign prostatic hyperplasia (BPH) patients.

Methods

The Patient Health Questionnaire (PHQ-9) for depression, the International Prostate Symptom Score (IPSS) for the severity of LUTS and the brief Illness Perception Questionnaire (B-IPQ) for illness perceptions (IPs) were used among the 157 BPH patients with LUTS. Pearson’s correlation test and hierarchical regression analyses were used to assess the correlations between LUTS, depressive symptoms and IPs.

Results

Our study found that the severity of LUTS was associated with depressive symptoms and subscales of illness perception; meanwhile, IPs were associated with the level of education. A positive relationship was found between the scores of PHQ9 and the B-IPQ subscales of illness consequences, identity, timeline, concern and emotion; thus, a negative correlation was found between scores of PHQ9 and the B-IPQ subscales of illness coherence, personal control and treatment control. The hierarchical regression analysis showed IPSS and the B-IPQ subscales of illness consequences, concern and emotion were significantly associated with depression, and explained 85.1% of the variance in depressive symptoms (R² = 0.851, p < 0.05).

Conclusion

The relationship between LUTS and depressive symptoms may be mediated by the negative IPs, including consequences, concern and emotions. Clinicians should not only focus on the LUTS but also on the IPs to improve depressive symptoms among BPH patients.

Incidence and Risk Factors of Post-Operative Depression in Patients Undergoing Transurethral Resection of Prostate for Benign Prostatic Hyperplasia

Background

Benign prostatic hyperplasia (BPH) is a frequent-occurring disease in middle-aged and elderly men. This work is a prospective study and aims at exploring the incidence of post-operative depression and the potential risk factors of depression in a cohort of patients with BPH in China.

Methods

In this survey, 611 men who underwent transurethral resection of the prostate (TURP) were strictly selected at our institution from January 2016 to August 2019. Zung Self-rating Depression Scale was used for evaluation of depressive symptoms. Sociodemographic, clinical and other data were also collected.

Results

We found that 152/611 (24.9%) patients suffered from different degree of depression at 6 months after TURP, including mild symptoms (20.9%) and moderate/severe symptoms (3.9%). A total of 421 (68.9%) patients developed post-TURP erectile dysfunction (ED). The occurrence of depression was closely associated with marital status, education level, cigarette smoking, alcohol consumption, severity of lower urinary tract symptoms (LUTS), duration of BPH, erectile function, and comorbidities (such as diabetes, dyslipidaemia and bladder stone). The risk factors related to the severity of depression included widowed or single marital status, frequent alcohol consumption, moderate or severe LUTS, longer duration (> 5 years) of BPH, ED, urinary continence, and comorbidities such as diabetes and bladder stone.

Conclusion

Many risk factors are related to the occurrence of depression in patients undergoing TURP. Widowed or single marital status, frequent alcohol consumption, moderate or severe LUTS, longer duration of BPH, ED, urinary incontinence and comorbidities such as diabetes and bladder stone are connected with the increase odds of moderate or severe depressive symptom.

Marijuana, Alcohol, and ED: Correlations with LUTS/BPH

PURPOSE OF REVIEW

Benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) is a disease complex with enormous societal burden and yet the pathogenesis of LUTS/BPH is poorly understood. We set out to review the literature on the relationship between depression, marijuana usage, and erectile dysfunction (ED) to LUTS/BPH.

RECENT FINDINGS

LUTS/BPH has independent associations with depression as well as with ED. In each case, the causality and mechanistic relationship is unknown. The impact of marijuana, as it increasingly pervades the general population, on the disease complex of LUTS/BPH is not well studied but recent results support short-term benefit and long-term caution. Depression, a form of central nervous dysfunction, and ED, which is likely mediated via endothelial dysfunction, are independently associated with LUTS/BPH. The presence of cannabinoid receptors in urologic organs, coupled with recent population studies, supports a modulatory effect of marijuana on voiding although an enormous knowledge gap remains.
