The Presence of Overactive Bladder Wet Increased the Risk and Severity of Erectile Dysfunction in Men with Type 2 Diabetes

Association between nocturia and serum albumin in the U.S. adults from NHANES 2005-2012

BACKGROUND

Nocturia, a prevalent chronic condition, impacts individuals' quality of life but remains underexplored. This study aimed to assess the association between serum albumin levels and nocturia.

METHODS

Based on the analysis of the National Health and Nutrition Examination Survey (NHANES) database (2005-2012), our study included a total of 6345 adults (≥20 years old). Nocturia was defined as ≥2 nocturnal voiding episodes. Logistic regression and smooth curve fitting analyzed the linear and nonlinear correlations between serum albumin and nocturia, with subgroup analysis.

RESULTS

Among 6345 participants, 1821 (28.7%) experienced nocturia. Logistic regression analysis revealed a linear negative correlation between serum albumin and nocturia risk (OR = 0.9549, 95% CI = 0.9280 ~ 0.9827, P = 0.002). Even after quartile division of serum albumin concentration, this correlation persisted within each group, and a smooth curve fitting validated the nonlinear negative correlation between the two. Subgroup analysis further demonstrated significant impacts of body mass index (BMI), alcohol consumption, and age on this association.

CONCLUSION

This cross-sectional study indicated that higher serum albumin levels were associated with a reduced risk of nocturia in U.S. adults aged 20 and older, highlighting the importance of serum albumin in the prevention and treatment of nocturia and providing clinical guidance.

Serum albumin levels as a useful complementary marker for erectile dysfunction in ulcerative colitis: A cross-sectional study

OBJECTIVE

Recently, a close association between ulcerative colitis (UC) and erectile dysfunction (ED) was reported. An inverse relationship between serum albumin and ED is found in patients with chronic disease. However, the association between serum albumin levels and ED in patients with UC is unclear. This study aims to investigate this issue in Japanese patients with UC.

METHODS

One hundred and thirty-six Japanese male UC patients were enrolled in this study. Information on serum albumin levels and medications for UC from medical records, Sexual Health Inventory for Men (SHIM) score information from self-administered questionnaires and information on the severity of UC from physician reports were obtained from medical records, self-administered questionnaires, and reports from physicians. The participants were divided into tertiles based on the total protein, serum globulin, serum albumin, aspartate aminotransferase, and C-reactive protein levels. The definition of ED and severe ED was SHIM score < 22 and SHIM score < 8, respectively. The association between these serum markers and ED was assessed by multivariate logistic regression.

RESULTS

The prevalence of severe ED in the low, moderate, and high albumin groups was 66.0%, 51.0%, and 28.3%, respectively. After adjusting for confounding factors, the low albumin group was independently and positively associated with severe ED (adjusted odds ratio: 2.74, 95% confidence interval: 1.03-7.48, p for trend =0.044). No association between other marker and ED was found.

CONCLUSION

Serum albumin was independently inversely associated with severe ED in Japanese patients with UC. Hypoalbuminemia might be a useful complementary marker for assessing the prevalence and severity of ED in UC patients.

Serum albumin levels and stress urinary incontinence in females: A retrospective study based on NHANES 2007-2016

Background

Serum albumin (sAlb) is an essential indicator of human physiological function. However, the correlation between the concentration of sAlb and stress urinary incontinence (SUI) remains poorly understood.

Methods

The sAlb was measured using the bichromatic digital endpoint method. The SUI was assessed according to information from the National Health and Nutrition Examination Survey (NHANES) questionnaire. Univariate and multivariate logistic regression analyses of the potential correlation between sAlb and stress incontinence were performed. Subgroup analysis was also conducted according to body mass index (BMI).

Results

After adjusting for potential key confounders, sAlb was found to have a significant association with SUI in adult females, and higher sAlb levels were associated with a lower risk of SUI (OR = 0.849; 95 % CI: 0.724-0.994; P = 0.042). Furthermore, subgroup analysis indicated that sAlb was associated with reduced SUI risk only in the subgroup with a body mass index (BMI) ≥ 30 (OR = 0.762; 95 % CI: 0.595-0.975; P = 0.030).

Conclusion

Female SUI was correlated with sAlb concentration, and a lower risk of SUI was seen in those with greater sAlb levels. These findings provide new insights into SUI prevention.

International Continence Society (ICS) report on the terminology for sexual health in men with lower urinary tract (LUT) and pelvic floor (PF) dysfunction

INTRODUCTION

The terminology for sexual health in men with lower urinary tract (LUT) and pelvic floor (PF) dysfunction has not been defined and organized into a clinically based consensus terminology report. The aim of this terminology report is to provide a definitional document within this context that will assist clinical practice and research.

METHODS

This report combines the input of the members of sexual health in men with LUT and PF Dysfunction working group of the International Continence Society (ICS), assisted at intervals by external referees. Appropriate core clinical categories and a sub-classification were developed to give coding to definitions. An extensive process of 18 rounds of internal and external review was involved to exhaustively examine each definition, with decision-making by collective opinion (consensus). The Committee retained evidence-based definitions, identified gaps, and updated or discarded outdated definitions. Expert opinions were used when evidence was insufficient or absent.

RESULTS

A terminology report for sexual health in men with LUT and PF dysfunction, encompassing 198 (178 NEW) separate definitions, has been developed. It is clinically based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different speciality groups involved. Conservative and surgical managements are major additions and appropriate figures have been included to supplement and clarify the text. Emerging concepts and measurements, in use in the literature and offering further research potential, but requiring further validation, have been included as an appendix. Interval (5-10 years) review is anticipated to keep the document updated.

CONCLUSION

A consensus-based terminology report for sexual health in men with LUT and PF dysfunction has been produced to aid clinical practice and research. The definitions that have been adopted are those that are most strongly supported by the literature at this time or are considered clinical principles or consensus of experts' opinions.

Nocturia and prevalence of erectile dysfunction in Japanese patients with type 2 diabetes mellitus: The Dogo Study

Aims/Introduction

Several epidemiological studies have reported a positive association between nocturia and erectile dysfunction (ED). Yet only limited evidence exists regarding the association between nocturia and ED among patients with type 2 diabetes mellitus, although nocturia and ED are common among type 2 diabetes mellitus patients.

Material and Methods

Study participants were 332 male Japanese patients with type 2 diabetes mellitus, aged 19–70 years, who had undergone blood tests at our institutions. A self‐administered questionnaire was used to collect information on the variables under study. Adjustment was made for age, body mass index, hypertension, stroke, ischemic heart disease, glycated hemoglobin and diabetic neuropathy. ED, moderate to severe ED and severe ED were defined as present when a participant had a Sexual Health Inventory for Men score <22, <12 and <8, respectively. Study participants were considered to have nocturia if they answered ‘once or more’ to the question: ‘Within 1 week, how many times do you typically wake up to urinate from sleeping at night until waking in the morning?’

Results

The prevalence of nocturia was 79.8%. Nocturia was independently positively associated with ED and moderate to severe ED: the adjusted odds ratios were 7.86 (95% confidence interval 2.11–33.56) and 2.17 (95% confidence interval 1.16–4.12), respectively. The positive association between nocturia and severe ED fell just short of significance.

Conclusions

In Japanese men with type 2 diabetes mellitus, nocturia might be associated with ED and moderate to severe ED.

Several epidemiological studies have reported a positive association between nocturia and erectile dysfunction (ED).

Yet only limited evidence exists regarding the association between nocturia and ED among patients with type 2 diabetes mellitus, although nocturia and ED are common among type 2 diabetes mellitus patients.

Hormonal determinants of erectile dysfunction and lower urinary tract symptoms in middle-aged and elderly men with prediabetes

OBJECTIVES

Erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) are common in diabetic men. The aim of this study was to investigate hormonal determinants, the prevalence and severity of ED and LUTS in middle-aged and elderly men with prediabetes (PD).

METHODS

We investigated 176 men with PD and 184 healthy peers. PD was defined according American Diabetes Association. ED according IIEF scale and LUTS according IPSS scale were assessed. Total testosterone (TT), calculated free testosterone (cFT), dehydroepiandrosterone sulfate (DHEAS) and insulin-like growth factor 1 (IGF-1) were measured.

RESULTS

The prevalence of ED in patients with PD was higher than in control group (30 versus 24%) as well as the prevalence and severity of ED and LUTS in elderly (60-80 years) and middle-aged (40-59 years) men with PD was higher than in healthy peers. In middle-aged pre-diabetic men, the more severe LUTS symptoms were associated with low TT and DHEAS, while in elderly men with low cFT and DHEAS. The higher prevalence of ED in middle-aged men with PD was associated with cFT and DHEAS, while in elderly pre-diabetic men with TT and IGF-1.

CONCLUSIONS

The prevalence and severity of LUTS and ED symptoms were higher in pre-diabetic men than in healthy peers. Hormonal determinants of these symptoms are different in middle-aged and elderly patients with PD.

Lower urinary tract symptoms and erectile dysfunction in men with type 2 diabetes mellitus

Purpose

To assess the prevalence of lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) and the relationships between LUTS, ED, depression, and other factors in Korean men with type 2 diabetes mellitus (T2DM).

Methods

This cross-sectional study included 124 male patients with T2DM who attended a university hospital diabetes clinic between October 2010 and April 2012. Data were collected using structured interviews and chart reviews. LUTS were measured using the International Prostate Symptom Score (IPSS), ED using the five-item Korean version of the International Index of Erectile Function (IIEF), depression using the Center for Epidemiologic Studies Depression Scale, and glycosylated hemoglobin level from clinical data.

Results

The IPSS score was 9.2±6.6. The total IPSS scores indicated that 53.3% of the subjects had either moderate or severe symptoms. The mean IIEF score was 7.3±8.6, indicating the severity of ED to be mild, mild to moderate, moderate, and severe in 10.5%, 9.7%, 1.6%, and 66.9% of the participants, respectively. LUTS showed a significant negative correlation with ED (r=-0.26, P=0.003) and a significant positive correlation with depression (r=0.33, P<0.001). ED was negatively correlated with age (r=-0.44, P<0.001), duration of diabetes (r=-0.26, P=0.004), and depression (r=-0.24, P=0.008).

Conclusions

LUTS and ED were found to have a high prevalence among Korean men with T2DM. More severe ED was associated with worse LUTS, whereas more severe depressive symptoms were found to be associated with more severe ED and LUTS.

The influence of ethanol intake on RhoA/Rho kinase signaling pathway in corpus cavernosum of OLETF rats

PURPOSE

To investigate the effect of the ethanol on corpus cavernosum of the type 2 diabetes mellitus (type 2 DM) rat, since previous studies have reported the positive effect of moderate drinking on type 2 DM and endothelial function.

METHODS

Otsuka Long Evans Tokushima Fatty (OLETF, n = 28) and Long Evans Tokushima Otsuka (LETO, n = 28) male rats were assigned to four groups: control (LETO, n = 14), control/ethanol (LETO with ethanol, n = 14), fatty (OLETF, n = 14) and fatty/ethanol (OLETF with ethanol, n = 14). The control/ethanol and fatty/ethanol groups were fed Lieber-DeCarli Regular EtOH. After 10 weeks, an intraperitoneal glucose tolerance test (IPGTT) was performed. RT-PCR and Western blot analyses of the RhoA/Rho kinase in the corpus cavernosum were performed. The expression of endothelial nitric oxide synthase (eNOS) and neuronal nitric oxide synthase (nNOS) in the corpus cavernosum was evaluated by immunohistochemistry.

RESULTS

After a 10-week ethanol intake, the body weight and the IPGTT of the fatty/ethanol group were significantly lower compared with the fatty group (p < 0.05). A significantly increased mRNA and protein expression in the fatty group was observed compared with the control group by RT-PCR and Western blot analyses (p < 0.05): A significantly decreased expression was observed in the fatty/ethanol group compared with the fatty group (p < 0.05). The significantly increased expression of eNOS was observed in the fatty/ethanol group compared with the fatty group by immunohistochemistry.

CONCLUSIONS

Long-term ethanol intake may preserve the erectile function in type 2 DM through the down-regulation of the RhoA/Rho kinase pathway.
