Metabolic analysis using HR-MAS in prostate tissue for prostate cancer diagnosis. Prostate 2024; 84:549-559. [PMID: 38212952 DOI: 10.1002/pros.24670] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 12/14/2023] [Accepted: 12/27/2023] [Indexed: 01/13/2024]
Abstract
INTRODUCTION In this study we used nuclear magnetic resonance spectroscopy in prostate tissue to provide new data on potential biomarkers of prostate cancer in patients eligible for prostate biopsy. MATERIAL AND METHODS Core needle prostate tissue samples were obtained. After acquiring all the spectra using a Bruker Avance III DRX 600 spectrometer, tissue samples were subjected to routine histology to confirm presence or absence of prostate cancer. Univariate and multivariate analyses with metabolic and clinical variables were performed to predict the occurrence of prostate cancer. RESULTS A total of 201 patients, were included in the study. Of all cores subjected to high-resolution magic angle spinning (HR-MAS) followed by standard histological study, 56 (27.8%) tested positive for carcinoma. According to HR-MAS probe analysis, metabolic pathways such as glycolysis, the Krebs cycle, and the metabolism of different amino acids were associated with presence of prostate cancer. Metabolites detected in tissue such as citrate or glycerol-3-phosphocholine, together with prostate volume and suspicious rectal examination, formed a predictive model for prostate cancer in tissue with an area under the curve of 0.87, a specificity of 94%, a positive predictive value of 80% and a negative predictive value of 84%. CONCLUSIONS Metabolomics using HR-MAS analysis can uncover a specific metabolic fingerprint of prostate cancer in prostate tissue, using a tissue core obtained by transrectal biopsy. This specific fingerprint is based on levels of citrate, glycerol-3-phosphocholine, glycine, carnitine, and 0-phosphocholine. Several clinical variables, such as suspicious digital rectal examination and prostate volume, combined with these metabolites, form a predictive model to diagnose prostate cancer that has shown encouraging results.

Abstract
The prevalence of substance use globally is rising and is highest among men of reproductive age. In Africa, and South and Central America, cannabis use disorder is most prevalent and in Eastern and South-Eastern Europe, Central America, Canada and the USA, opioid use disorder predominates. Substance use might be contributing to the ongoing global decline in male fertility, and emerging evidence has linked paternal substance use with short-term and long-term adverse effects on offspring development and outcomes. This trend is concerning given that substance use is increasing, including during the COVID-19 pandemic. Preclinical studies have shown that male preconception substance use can influence offspring brain development and neurobehaviour through epigenetic mechanisms. Additionally, human studies investigating paternal health behaviours during the prenatal period suggest that paternal tobacco, opioid, cannabis and alcohol use is associated with reduced offspring mental health, in particular hyperactivity and attention-deficit hyperactivity disorder. The potential effects of paternal substance use are areas in which to focus public health efforts and health-care provider counselling of couples or individuals interested in conceiving.

Abstract
OBJECTIVE The association between alcohol use and erectile dysfunction (ED) has not been explored adequately. The aim of this study is (i) to determine the prevalence of ED in patients with Alcohol use disorder (AUD), (ii) the association of ED with sociodemographic and clinical variables, (iii) the association between severity of drinking and sociodemographic and clinical variables, and (iv) the assess the change in ED after one month of abstinence from alcohol. METHODS 203 consecutive patients were recruited into the study after taking written informed consent. Sociodemographic data was collected using a proforma and ED was assessed using International Index of Erectile Function-5 (IIEF-5). The patients were also followed up after 1 month of abstinence to assess the change in erectile function. RESULTS The prevalence of ED was 68.5%. Out of the 203 subjects, 28.1% had mild ED, 24.1% had mild to moderate ED, 9.9% had moderate ED and 6.4% had severe ED. Significant association were seen between ED and age, marital status, diabetes mellitus, hypertension, total duration, and severity of drinking. A significant association was seen between severity of drinking and age, diabetes mellitus, hypertension, alcoholic liver disease, tobacco use and duration of drinking. The improvement in ED after 1 month abstinence was found to be significant. CONCLUSIONS ED is a common problem in patients with AUD. Routine assessment of sexual functioning is warranted in patients with AUD and the information that ED improves with abstinence can provide an impetus to change.

Abstract
Background The existing literature on alcohol-induced sexual dysfunction has mainly deliberated on erectile dysfunction and premature ejaculation, ignoring other important domains of sexual dysfunctions (viz sexual pleasure, sexual desire, arousal, orgasmic function). This study was undertaken to assess the extent of alcohol-associated sexual dysfunction and to compare their severity with the severity of alcohol dependence in males. Methods A cross-sectional descriptive study design recruited 78 male patients and an assessment was conducted using the Changes in sexual functioning questionnaire male clinical version, International index of erectile function scale, Severity of Alcohol Dependence Questionnaire, Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) and International Classification of Diseases-10 (ICD-10). A correlation between years of alcohol consumed and its effect on various domains of sexual dysfunction was also carried out using Pearson's correlation coefficient. Results Seventy-seven percent of the study population had complaints of sexual dysfunction in one or more domains, with reduced sexual pleasure (71.8%) as the most common followed by low sexual desire (in terms of frequency) in 61.5% and erectile dysfunction in 43.6%. The severity of the sexual dysfunction was found to be directly proportional to the severity of alcohol dependence with almost 100 percent of the patients with severe alcohol dependence having sexual dysfunction in all the domains. Conclusion The most common sexual dysfunction reported in the current study was decreased sexual pleasure (71.8%) followed by low sexual desire 61.5% (in terms of frequency). These findings emphasize the fact, that alcohol significantly compromises almost all domains of sexual functioning in addition to erectile dysfunction.

Abstract
BACKGROUND AND AIMS We aim to compare the various risk factors for erectile dysfunction (ED) in type 2 diabetes mellitus (DM) and nondiabetic patients. MATERIALS AND METHODS We retrospectively collected and evaluated the data of 175 OPD patients with ED. We included 138 patients of ED from endocrinology and urology OPD after exclusion. ED was assessed by using a questionnaire adapted from the abridged five-item version of the International Index of Erectile Function (IIEF-5) score. RESULTS A total of 96 (69.56%) were diabetic, and 42 (30.43%) were nondiabetic. The majority of patients (62.31 %) were in the age group of 40-60 years. Thirty-nine (28.26%) were alcoholics, and 55 (40%) were smokers. The average duration of diabetes was 6.6±1.5 years. Hypertension was present in 49 (35.5%). Diabetic patients were significantly older (47.9±8.2 vs. 40.2±7.6 years, p=0.0001) and obese (BMI (kg/m2), 27.3±5.4 vs. 24.6±3.9, p=0.004). Waist circumference in diabetics was 95.3±10.9, as compared to nondiabetics, which was 89.6±9.2 cm (p=0.0037). The IIEF-5 score was significantly lower in diabetic subjects in comparison to nondiabetics (9.4±3.2 vs. 12.1±3.6 p=0.0001). Moderate-to-severe ED was more common in diabetic patients (76%) in comparison to nondiabetics (59.5%). The prevalence of mild and mild-to-moderate ED was 11.45 % and 12.5 % in diabetic patients in comparison to 16.7% and 23.5% in nondiabetics, respectively. The prevalence of hypertension and coronary artery was higher in diabetics in comparison with nondiabetics. Hypertension was significantly higher in diabetic patients with ED (42.7% vs. 19.04%, p=0.0075), but coronary artery disease was not statistically significant (8.3% vs. 2.3%, p=0.1925). LH (2.6±0.7 vs. 3.5±0, p=0.0001) and testosterone (312.1±110.7 vs. 367.8±115.1, p=0.0081) were significantly lower in diabetics in comparison to nondiabetics. CONCLUSIONS The IIEF-5 score was lower in diabetic cases as compared to those without diabetes. The factors that significantly contributed to ED in type 2 DM patients, as compared to nondiabetic patients, were age, BMI, waist circumference, hypertension, poor glycemic control, LH, and testosterone levels.

Abstract
Background Alcohol is a potent substance that causes both acute and chronic changes in almost all neurochemical systems, with the result that heavy drinking can produce serious psychological symptoms including depression, anxiety, and psychoses. It also affects sexual health adversely and causes sexual dysfunction. Methods This study aimed to find the prevalence and pattern of sexual dysfunction in male patients with alcohol dependence. This cross-sectional study included 100 patients attending psychiatry out patient department (OPD) at a tertiary care center in west India. Informed written consent was taken for collecting socio-demographic and clinical data in a uniform and standard manner. Sexual dysfunction was assessed using a sexual dysfunction checklist, constructed by Arackal and Benegal at the national institute of mental health and neuroscience, Bangalore containing 12 items from the diagnostic criteria for research and ICD-10 classification of mental and behavioral disorders. The Leeds dependence questionnaire was used to assess the severity of alcohol dependence. Findings Sexual dysfunction was present in 62% of the patients. Among the patients, 36% had difficulty achieving an erection, 34% had difficulty maintaining an erection, 37% reported premature ejaculation, 7% had delayed ejaculation, 14% reported anorgasmia, 1% had ejaculation with a flaccid penis, 2% had pain during intercourse, 6% were dissatisfied with the frequency of intercourse, 4% were dissatisfied with their sexual partner, and 7% were dissatisfied with their performance. Conclusion Sexual dysfunction is significantly and positively associated with duration, amount of alcohol consumed per day, and severity of alcohol dependence.

Abstract
BACKGROUND Since December 2019, when it was first reported in Wuhan, province of Hubei, China, the new virus SARS-CoV-2 has spread rapidly around the world and has become a global pandemic. During the COVID-19 pandemic, due to the public health measures implemented, people's sexual activity has also been affected. Restrictions on people's activities, reduced sports activities, economic issues, increased psychological stress, and reduced entertainment have, indeed, dramatically impacted sexual activity and functioning. The purpose of this study was tosystematically identify, collect and summarize the existing body of evidence from published studies on the effects of COVID-19 pandemic on sexual activity and functioning. METHODS Several scholarly databases, namely MEDLINE (via PubMed interface), Web of Science (WOS), Embase, CINAHL, the Cochrane Library, Scopus, and PsycINFO databases, were mined from December 2019 to the end of January 2021. We utilized a random-effect meta-analytical model to analyze all the data. More in detail, the Standardized Mean Difference (SMD) was used in order to estimate and evaluate the effects of the COVID-19 pandemic on sexual activity and functioning. RESULTS Twenty-one studies were included in the present study. In total, 2454 women and 3765 men were evaluated. In the present meta-analysis, sexual functioning and activity were assessed by means of two standardized and reliable tools, namely the "Female Sexual Function Index" (FSFI) and the "International Index of Erectile Function-5 items" (IIEF-5). A total of 5 studies reported the FSFI score before and after the COVID-19 pandemic in female participants. Based on the random-effect model, the SMD was computed to be - 4.26 [95% confidence interval or CI: - 7.26, - 1.25], being statistically significant. A total of 3 studies reported the IIEF-5 score before and after the COVID-19 pandemic in male participants. Based on the random-effect model, the SMD was computed to be - 0.66 [CI 95%: - 0.99, - 0.33], being statistically significant. In the majority of these studies, participants reported a reduction in the number of sexual relations and an increase in the frequency of solo sex activity, especially masturbation, compared to the time prior to the COVID-19 pandemic. CONCLUSION The results of the present study showed that COVID-19 related restrictions were correlated with higher rates of sexual dysfunction and reduced sexual activity; however, results of the current meta-analytical study show that this change in sexual functioning was greater in women compared to men. Sex is one of the dimensions of every person's life; therefore, researchers should identify the factors that lead to sexual dysfunction due to COVID-19 pandemic in their community. In this regard, sexologists should design and implement effective programs to reduce the heterogeneous causes affecting sexual functioning, given the psychological strain that the COVID-19 pandemic puts on individuals.

Abstract
Testosterone (T) deficiency and erectile dysfunction (ED) are independently functionally and socially impairing, and their concurrence in men can be challenging to treat. Successful management requires an understanding of the mechanisms through which T underlies normal erectile function. While the literature elucidating some of these mechanisms is vast (e.g., androgen regulation of the activity of nitric oxygen synthase and phosphodiesterase type 5) for others it is scarce (e.g., catalysts of castration-induced corporal fibrosis). The randomized controlled trial data for the efficacy of T replacement as mono- or combination therapy to treat ED has been conflicting. Positive results were frequently not clinically meaningful. Meta-analyses have been helpful in illuminating trends that seem to be promising. Consensus is still lacking in several areas, such as the threshold of low T severity for which replacement therapy is most beneficial; the timing for initiating combination therapy; and the duration of treatment.

Abstract
Erectile dysfunction (ED) has been identified as one of the most frequent chronic complications of diabetes mellitus (DM). The prevalence of ED is estimated to be about 67.4% in all DM cases worldwide. The pathophysiological process leading to ED involves endothelial, neurological, hormonal, and psychological factors. In DM, endothelial and neurological factors play a crucial role. Damages in the blood vessels and erectile tissue due to insulin resistance are the hallmark of ED in DM. The current treatments for ED include phosphodiesterase-5 inhibitors and penile prosthesis surgery. However, these treatments are limited in terms of just relieving the symptoms, but not resolving the cause of the problem. The use of stem cells for treating ED is currently being studied mostly in experimental animals. The stem cells used are derived from adipose tissue, bone, or human urine. Most of the studies observed an improvement in erectile quality in the experimental animals as well as an improvement in erectile tissue. However, research on stem cell therapy for ED in humans remains to be limited. Nevertheless, significant findings from studies using animal models indicate a potential use of stem cells in the treatment of ED.

Abstract
PURPOSE The purpose of the study was to evaluate the association between alcohol consumption and risk of erectile dysfunction (ED). METHODS PubMed was searched for reports published before June 2019. Data were extracted and combined odds ratios (ORs) calculated with random-effects models. RESULTS Finally, 46 studies were included (216,461 participants). The results of our meta-analysis indicated that there was a significant association between regular alcohol consumption and ED (OR 0.89, 95% confidence interval [CI]: 0.81-0.97). There was no indication of publication bias (Egger's test, p = 0.37). In the stratified analysis, the pooled OR of ED for light to moderate and high alcohol consumption was 0.82 (95% CI: 0.72-0.94) and 0.82 (95% CI: 0.67-1.00), respectively. No variable related to the source of heterogeneity was found in univariate and multivariate meta-regression analyses. A dose-response meta-analysis suggested that a nonlinear relationship between alcohol consumption and risk of ED was observed (p for nonlinearity <0.001). CONCLUSION A J-shaped relationship between alcohol consumption and risk of ED was observed. Alcohol should be taken in moderate quantities in order to obtain the dual effect of disinhibition and relaxation. If taken chronically, it could provoke vascular damages.

Abstract
BACKGROUND The prevalence of diabetes has been rising increasing rapidly in middle- and low-income countries. In Africa, the World Health Organization projections anticipate diabetes mellitus to be the seventh leading cause of death in by 2030. Alcohol consumption influences diabetes evolution, in such a way that it can interfere with self-care behaviours which are important determinants of diabetes prognosis. In this study, we evaluated factors associated with alcohol consumption among persons with diabetes in Kampala to inform management policies and improve comprehensive diabetes care. METHODOLOGY A cross-sectional study was conducted systematically among 290 adults with diabetes, attending diabetic clinics at Mulago National Referral Hospital and St Francis Hospital Nsambya. Data were entered and analysed in Epi-Info version 7 and STATA 13 software. Modified Poisson regression was used to identify factors associated with alcohol consumption among persons with diabetes. All tests were two-sided and the significance level for all analyses was set to p < 0.05. RESULTS The prevalence of alcohol consumption among persons with diabetes was 23.45% [95% CI: 18.9-28.7%]. Divorced, separated and widowed patients (Adj PR: 0.42, 95% CI: 0.21-0.83); and Protestant (Adj PR: 0.44, 95% CI: 0.24-0.82); Muslim (Adj PR: 0.30, 95% CI: 0.14-0.62); and Pentecostal (Adj PR: 0.32, 95% CI: 0.15-0.65) patients were less likely to consume alcohol. Diabetic patients who had a diabetes duration greater than 5 years were more likely to consume alcohol (Adj PR: 1.90, 95% CI: 1.25-2.88). CONCLUSION Approximately one-quarter of participants consumed alcohol. However being catholic, never being married and having diabetes for more than 5 years predisposed persons with diabetes to alcohol consumption. Sensitization messages regarding alcohol consumption among persons with diabetes should be target patients who have never been married and those who have spent more than 5 years with diabetes; religion should also be considered as an important venue for health education in the community.

Abstract
Modifiable lifestyle-related risk factors are the object of increasing attention, with a view to primary and tertiary prevention, to limit the onset and development of diseases.Also in the urological field there is accumulating evidence of the relationship between urological diseases and lifestyle-related risk factors that can influence their incidence and prognosis. Risk factors such as nutrition, physical activity, sexual habits, tobacco smoking, or alcohol consumption can be modified to limit morbidity and reduce the social impact and the burdensome costs associated with diagnosis and treatment.This review synthesizes the current clinical evidence available on this topic, trying to satisfy the need for a summary on the relationships between the most important lifestyle factors and the main benign urological diseases, focusing on benign prostatic hyperplasia (BPH), infections urinary tract (UTI), urinary incontinence (UI), stones, erectile dysfunction, and male infertility.

Abstract
Purpose To evaluate the effect of chronic alcoholism on morphometry and apoptosis mechanism and correlate with miRNA-21 expression in the corpus cavernosum of rats. Methods Twenty-four rats were divided into two experimental groups: Control (C) and Alcoholic group (A). After two weeks of an adaptive phase, rats from group A received only ethanol solution (20%) during 7 weeks. The morphometric and caspase-3 immunohistochemistry analysis were performed in the corpus cavernosum. The miRNA-21 expression was analyzed in blood and cavernous tissue. Results Chronic ethanol consumption decreased cavernosal smooth muscle area of alcoholic rats. The protein expression of caspase 3 in the corpus cavernosum was higher in A compared to the C group. There was no difference in the expression of miRNA-21 in serum and cavernous tissue between the groups. Conclusion Chronic ethanol consumption reduced smooth muscle area and increased caspase 3 in the corpus cavernosum of rats, without altered serum and cavernosal miR-21 gene expression.

Abstract
Alcohol, despite salutary associations with sexuality, has been implicated in sexual health problems. This review examines the relationship between alcohol and outcomes related to sexual health. Methodological considerations limiting causal assertions permissible with nonexperimental data are discussed, as are advantages of experimental methods. Findings from laboratory experiments are reviewed evaluating causal effects of acute alcohol intoxication on a variety of outcomes, including sexual arousal, sexual desire, orgasm, and sexual risk behaviors related to sexually transmitted infections (STIs) and human immunodeficiency virus (HIV). Several variables exerting mediating and moderating influences are identified. It is concluded that acute alcohol intoxication is capable of exerting a causal impact on multiple constituent components of sexual responding related to sexual health. Both alcohol expectancy and alcohol myopia theories have been supported as explanations for these causal effects. Furthermore, for sexual risk behavior, noteworthy recent developments include research highlighting the importance of women's sexual victimization history and men's condom use resistance. Limitations and implications associated with this body of research are also discussed.

Abstract
Benign prostatic hyperplasia (BPH) is very common in aging men and causes lower urinary tract symptoms (LUTS), which decrease health-related quality of life. A number of evidence suggests that other than ageing, modifiable factors, such as increasing prostate volume, obesity, diet, dyslipidemia, hormonal imbalance, hypertension, metabolic syndrome, alcohol, and smoking, also contribute to the development of BPH and/or LUTS. More recently, erectile dysfunction (ED) has been linked to LUTS/BPH as a part of this syndrome, suggesting that patients with BPH or LUTS easily develop ED, and that LUTS/BPH symptoms often coexist with ED. This article focuses on the epidemiology and risk factors of the combined phenotype LUTS/BPH - ED.

Abstract
Introduction: Alcoholism impairs female sexual functions (decreased sex drive, reduced vaginal fluid, difficulty to experience orgasm). Aim: The aim of this study was to evaluate the course of perimenopausal period and sexual life of female alcoholics. Methods: 97 women at the age of 40–60 years were qualified with a diagnosed history of alcoholism (studied group). For the control group, 92 women at the age of 40–60 without a history of alcoholism were qualified. Questionnaires assessing female sexual function (Female Sexual Function Index—FSFI), the severity of perimenopausal symptoms (Menopause Rating Scale—MRS) and the degree of alcohol addiction (Michigan Alcoholism Screening Test—MAST) were obtained from each participant. Main outcome measures: To assess the sexual function of perimenopausal women addicted to alcohol. Results: The studied and control groups were significantly different (p = 0.00) in terms of severity of menopausal symptoms (MRS). The research showed lower quality of sexual life (FSFI) of women from the studied group. Conclusions: Population of women with diagnosed alcohol dependence enter the menopausal stage at the similar age as the population of female non-drinkers. The time of alcohol abuse is an important factor having an impact on both the course of menopause and the dynamics of the perimenopause period, leading to symptom escalation. The population of female alcoholics shows a decrease in sexual activity and the prevalence of sexual disorders.

Abstract
BACKGROUND Sexual dysfunction is a common problem among men and women and is associated with negative individual functioning, relationship difficulties, and lower quality of life. AIM To determine the magnitude of associations between 6 health-related lifestyle factors (cigarette smoking, alcohol intake, physical activity, diet, caffeine, and cannabis use) and 3 common sexual dysfunctions (erectile dysfunction, premature ejaculation, and female sexual dysfunction). METHODS A comprehensive literature search of 10 electronic databases identified 89 studies that met the inclusion criteria (452 effect sizes; N = 348,865). Pooled mean effects (for univariate, age-adjusted, and multivariable-adjusted estimates) were computed using inverse-variance weighted random-effects meta-analysis and moderation by study and population characteristics were tested using random-effects meta-regression. RESULTS Mean effect sizes from 92 separate meta-analyses provided evidence that health-related lifestyle factors are important for sexual dysfunction. Cigarette smoking (past and current), alcohol intake, and physical activity had dose-dependent associations with erectile dysfunction. Risk of erectile dysfunction increased with greater cigarette smoking and decreased with greater physical activity. Alcohol had a curvilinear association such that moderate intake was associated with a lower risk of erectile dysfunction. Participation in physical activity was associated with a lower risk of female sexual dysfunction. There was some evidence that a healthy diet was related to a lower risk of erectile dysfunction and female sexual dysfunction, and caffeine intake was unrelated to erectile dysfunction. Publication bias appeared minimal and findings were similar for clinical and non-clinical samples. CLINICAL TRANSLATION Modification of lifestyle factors would appear to be a useful low-risk approach to decreasing the risk of erectile dysfunction and female sexual dysfunction. STRENGTHS AND LIMITATIONS Strengths include the testing of age-adjusted and multivariable-adjusted models and tests of potential moderators using meta-regression. Limitations include low statistical power in models testing diet, caffeine, and cannabis use as risk factors. CONCLUSION Results provide compelling evidence that cigarette smoking, alcohol, and physical activity are important for sexual dysfunction. Insufficient research was available to draw conclusions regarding risk factors for premature ejaculation or for cannabis use as a risk factor. These findings should be of interest to clinicians treating men and women with complaints relating to symptoms of sexual dysfunction. Allen MS, Walter EE.

Abstract
Recent evidence shows that chronic ethanol consumption increases endothelin (ET)-1 induced sustained contraction of trabecular smooth muscle cells of the corpora cavernosa in corpus cavernosum of rats by a mechanism that involves increased expression of ETA and ETB receptors. Our goal was to evaluate the effects of alcohol and diabetes and their relationship to miRNA-155, miRNA-199 and endothelin receptors in the corpus cavernosum and blood of rats submitted to the experimental model of diabetes mellitus and chronic alcoholism. Forty-eight male Wistar rats were divided into four groups: control (C), alcoholic (A), diabetic (D), and alcoholic-diabetic (AD). Samples of the corpus cavernosum were prepared to study the protein expression of endothelin receptors by immunohistochemistry and expression of miRNAs-155 and -199 in serum and the cavernous tissue. Immunostaining for endothelin receptors was markedly higher in the A, D, and AD groups than in the C group. Moreover, a significant hypoexpression of the miRNA-199 in the corpus cavernosum tissue from the AD group was observed, compared to the C group. When analyzing the microRNA profile in blood, a significant hypoexpression of miRNA-155 in the AD group was observed compared to the C group. The miRNA-199 analysis demonstrated significant hypoexpression in D and AD groups compared to the C group. Our findings in corpus cavernosum showed downregulated miRNA-155 and miRNA-199 levels associated with upregulated protein expression and unaltered mRNA expression of ET receptors suggesting decreased ET receptor turnover, which can contribute to erectile dysfunction in diabetic rats exposed to high alcohol levels.

Abstract
BACKGROUND Men with prostate cancer often experience urinary and sexual dysfunction after treatment. Previous studies have demonstrated a relationship between dietary factors and these symptoms among men with diabetes or metabolic syndrome. However, there are limited data on whether diet after prostate cancer diagnosis, including a Mediterranean dietary pattern, affects urinary and sexual function among prostate cancer survivors. METHODS Men diagnosed with non-metastatic prostate cancer in the Health Professionals Follow-up Study (n = 2960) from 1986 to 2012 were prospectively followed for a median of 8.3 years after treatment. Participants completed validated dietary questionnaires every 4 years and a health-related quality of life assessment in 2010 or 2012. We used generalized linear models to examine associations between post-diagnosis Mediterranean Diet Score (including individual score components and dietary fat subtypes) and quality of life domains (sexual functioning, urinary irritation/obstruction, urinary incontinence) assessed using the Expanded Prostate Cancer Index Composite Short Form (score 0-100; higher scores indicate better function). RESULTS No statistically significant relationships were observed between the Mediterranean Diet Score after prostate cancer diagnosis and urinary or sexual function. However, the associations did vary depending on pre-diagnosis urinary and sexual dysfunction for urinary irritation/obstruction and sexual function scores, respectively (P-interactions < 0.0001). Men with higher post-diagnosis vegetable intake reported higher urinary incontinence scores (72 vs 76 comparing lowest to highest quintile; P-trend = 0.003). Similarly, higher vegetable intake and lower polyunsaturated fat intake were associated with higher urinary irritation/obstruction scores (vegetable: 80 vs 84 comparing lowest to highest quintile, P-trend = 0.01; polyunsaturated fat: 84 vs 78 comparing lowest to highest quintile, P-trend = 0.005), however these associations were observed only among men with urinary symptoms prior to their prostate cancer diagnosis. CONCLUSIONS Among men with prostate cancer, diet intake after diagnosis was not significantly associated with urinary or sexual function, although some relationships appeared to differ among men with and without symptoms prior to their prostate cancer diagnosis. Higher vegetable intake and lower polyunsaturated fat intake after prostate cancer diagnosis may be associated with better urinary function. However, this analysis was exploratory, and further research is needed to better delineate these relationships and guide dietary recommendations for men with prostate cancer.

Abstract
BACKGROUND Contrary to the popular belief concerning the aphrodisiac effects of alcohol, there exists scientific evidence which conclude on sexual dysfunction caused by chronic alcohol use. There is a dearth of studies from India. AIM The aim is to estimate the prevalence and correlates of sexual dysfunction in alcohol-dependent patients and to explore the association between sexual dysfunction and various alcohol-related variables. MATERIALS AND METHODS The study employed a cross-sectional descriptive design and recruited 84 male patients admitted for de-addiction in a tertiary care center. The evaluation was conducted using a specially designed intake proforma and tools such as Severity of Alcohol Dependence Questionnaire, Arizona Sexual Experience Scale, and International Classification of Disease, 10th revision, diagnostic criteria for research. RESULTS Thirty-seven percent of the patients had sexual dysfunction - the most common type being erectile dysfunction (25%), followed by dysfunction in satisfying orgasm (20%) and premature ejaculation (15.5%). Sexual dysfunction was significantly associated with the duration of alcohol dependence, amount of alcohol consumed per day, and severity of alcohol dependence. CONCLUSIONS Sexual dysfunction is common in male patients with alcohol dependence. The study highlights the detrimental effects of alcohol on sexual function and this information can be utilized in motivational interviewing of patients with alcohol dependence syndrome.

Abstract
Background & objectives: Sexual dysfunctions have been reported in alcohol-dependent men. Most of the studies conducted had limitation of using non-validated measures of sexual dysfunction and sampling design. This study was, therefore, conducted to determine the typology, demographic and clinical correlates of sexual dysfunction in alcohol-dependent men. Methods: One hundred and one patients with alcohol dependence (AD) attending the Drug De-addiction and Treatment Centre and 50 healthy controls were evaluated in this cross-sectional study. Participants in both the groups were assessed on Arizona Sexual experience scale (ASEX), Dyadic Adjustment Scale (DAS), Hamilton Depression Rating Scale (HDRS) and State-Trait Anxiety Inventory (STAI). In addition, patients with AD were assessed on Severity of Alcohol Dependence Questionnaire (SADQ) for severity of AD and revised clinical institute withdrawal assessment for alcohol scale (CIWA-Ar) to ensure that no participant was in active alcohol withdrawal state. Results: Overall, 58.4 per cent of patients in the AD group had sexual dysfunction. Among the domains, the highest frequency was seen for dysfunction for arousal (57.4%), followed by problems in desire (54.4%), erection (36.6%), satisfaction with orgasm (34.6%) and ability to reach orgasm was least affected (12.87%). The patient and control groups differed significantly in overall dyadic adjustment, in the domains of dyadic satisfaction and affective expression. Interpretation & conclusions: The finding of this study showed that a significant proportion of patients with AD has sexual dysfunction. Longitudinal studies using validated assessment tools should be done to confirm these findings.

Abstract
Erectile dysfunction (ED) has been well recognized as a marker of increased cardiovascular risk for more than 15 years, especially in younger men. Early detection of ED represents an opportunity to intervene to decrease the risk of future cardiovascular events and limit the progression of ED severity. Evidence suggests there is a window of opportunity of 3 to 5 years from the onset of ED to subsequent cardiovascular events. This opportunity is usually missed if the onus is placed on the patient to seek care for his sexual problems. Unfortunately, these clear messages have not been incorporated into routine cardiovascular care. The reasons for these disparities within specialties are discussed in this article, in addition to management algorithms. Lifestyle modification is usually recommended as the first-line treatment to correct ED and lessen cardiovascular risk, but evidence suggests that this might be effective only in men without established cardiovascular comorbidities. In men with type 2 diabetes mellitus and established cardiovascular disease, lifestyle modification alone is unlikely to be effective. Cardiovascular medications are often associated with sexual dysfunction but changes in medication are more likely to be beneficial in men with milder recent-onset ED. A balanced view must be taken related to medication adverse events, taking into account optimal management of established cardiovascular disease. Testosterone deficiency has been associated with different metabolic disorders, especially metabolic syndrome and type 2 diabetes mellitus. Testosterone deficiency syndrome has been associated with an independent burden on sexual function globally and increased cardiovascular and all-cause mortality. Testosterone replacement therapy has been shown to improve multiple aspects of sexual function and, in some studies, has been associated with a decrease in mortality, especially in men with type 2 diabetes mellitus. Recent studies have suggested that phosphodiesterase type 5 inhibitors, the first-line medications to treat ED, could decrease cardiovascular and all-cause mortality, through multiple mechanisms, predominantly related to improved endothelial function.

Erectile dysfunction is independently associated with apnea-hypopnea index and oxygen desaturation index in elderly, but not younger, community-dwelling men. Sleep Health 2017; 3:250-256. [PMID: 28709511 DOI: 10.1016/j.sleh.2017.04.006] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2017] [Revised: 04/01/2017] [Accepted: 04/20/2017] [Indexed: 02/06/2023]
Abstract
OBJECTIVE(S) To examine the association between obstructive sleep apnea (OSA) and other sleep indices using polysomnography (PSG) data and erectile dysfunction (ED) in a representative cohort of men. DESIGN Cross-sectional. SETTING Community-based. PARTICIPANTS Aged 40+ years (n=734; mean age [SD], 60.8 [10.9]). MEASUREMENTS Men with no prior OSA diagnosis who underwent in-home PSG (Embletta X100; 2010-11) and ED assessment (Global Impotence Rating) were selected. Un-adjusted and multi-adjusted regression models of ED were fitted against PSG measures, along with qualifying sociodemographic, lifestyle, and health-related covariates. Mediation effects were examined using the Baron-Kenny method. RESULTS Of the men examined, 24.7% (n=181) had ED, most notably in men older than 65years (cf. men 35-49 and 50-64years; P<.001). There was no significant association between ED and any of the PSG measures for allaged men. Given an observed ageinteraction within OSA categories (P=.005), analyses were repeated in age-stratified samples (<65 years; 65+ years). In men younger than 65years, only severe OSA was found to have an association with ED (2.01; 1.13-4.69) in unadjusted models. For men aged 65+ years, an independent association with ED was found for apnea-hyponea index (AHI; 1.55;1.02-2.36), moderate (AHI:10.0-19.9; 1.79;1.18-2.43), and severe (AHI:20.0+; 4.84;2.56-9.93) OSA, and oxygen desaturation index (ODI; both continuous [1.48;1.03-1.99] and >16 seconds [2.79;1.23-6.32]). The effect of AHI on ED was shown to be primarily mediated through ODI (63.4%, Sobel P value=.29). CONCLUSIONS In younger, community-based men, there appeared no independent relationship between objective measures of sleep and ED. However, there appears a strong, independent relationship between OSA, ODI, and ED in men 65 years and older.

Abstract
BACKGROUND Erectile dysfunction affects more than 100 million men worldwide, with a wide variability in prevalence. An overall association of cardiovascular risk factors, lifestyle and diet in the context of ED in a Mediterranean population is lacking. AIM To assess ED prevalence and associated factors in a Mediterranean cohort of non-diabetic patients with cardiovascular risk factors. METHODS Observational, cross-sectional study of patients aged over 40 treated at cardiovascular risk units in Catalonia. Anthropometric data, risk factors, lifestyle and diet habits were recorded. ED was assessed using the International Index of Erectile Function. RESULTS Four hundred and forty patients included, 186 (42.3%) with ED (24.8% mild, 6.8% moderate and 10.7% severe). ED presence and severity were associated with age, obesity, waist circumference, hypertension, antihypertensive treatment and ischaemic disease. Patients with ED were more frequently smokers, sedentary and consumed more alcohol. In multivariate analysis, consumption of nuts (> twice a week) (OR 0.41 (95% CI 0.25 to 0.67) and vegetables (≥ once a day) (OR 0.47 (95% CI 0.28-0,77)), were inversely related to ED. Obesity (as BMI ≥ 30 kg/m(2) ) (OR 2.49 (95% CI 1.48-4.17)), ischaemic disease (OR 2.30 (95% CI 1.22 to 4.33), alcohol consumption (alcohol-units a day) (OR 1.14 (95% CI 1.04 to 1.26), and age (year) (OR = 1.07 (95% CI 1.04-1.10) were directly related to ED. CONCLUSION Erectile dysfunction is a common disorder in patients treated in lipid units in Catalonia for cardiovascular risk factors. This condition is associated with age, obesity, ischaemic disease and unhealthy lifestyle habits.

Abstract
Diabetes mellitus and heavy alcohol consumption are both associated with vascular disease, a category that includes erectile dysfunction (ED). However, the association between alcohol consumption and ED among patients with type 2 diabetes mellitus remains unclear. The aim of the present multicenter cross-sectional study was to investigate the relationship between drinking frequency, weekly alcohol consumption, daily alcohol consumption, and ED among Japanese patients with type 2 diabetes mellitus. Study subjects were 340 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. ED was defined as present when a subject had a Sexual Health Inventory for Men score <8. Adjustment was made for age, body mass index, duration of type 2 diabetes mellitus, current smoking, hypertension, dyslipidemia, glycated hemoglobin, stroke, coronary artery disease, diabetic retinopathy, diabetic nephropathy, and diabetic neuropathy. The prevalence of ED was 43.2% (147/340). The frequency of alcohol consumption and weekly alcohol consumption were independently inversely associated with ED (p for trend p = 0.001 and 0.004, respectively). The relationship between daily alcohol consumption and ED was an inverted J-shaped curve: alcohol consumption of less than 60 g, but not 60 g or more, per day was independently related to a lower prevalence of ED (p for quadratic trend = 0.003). In Japanese men with type 2 diabetes mellitus, an inverted J-shaped relationship between daily alcohol consumption and ED was observed, while frequency of alcohol consumption and weekly alcohol consumption were significantly inversely associated with ED.

Abstract
Erectile dysfunction (ED) is a common medical disorder whose prevalence is increasing worldwide. Modifiable risk factors for ED include smoking, lack of physical activity, wrong diets, overweight or obesity, metabolic syndrome, and excessive alcohol consumption. Quite interestingly, all these metabolic conditions are strongly associated with a pro-inflammatory state that results in endothelial dysfunction by decreasing the availability of nitric oxide (NO), which is the driving force of the blood genital flow. Lifestyle and nutrition have been recognized as central factors influencing both vascular NO production, testosterone levels, and erectile function. Moreover, it has also been suggested that lifestyle habits that decrease low-grade clinical inflammation may have a role in the improvement of erectile function. In clinical trials, lifestyle modifications were effective in ameliorating ED or restoring absent ED in people with obesity or metabolic syndrome. Therefore, promotion of healthful lifestyles would yield great benefits in reducing the burden of sexual dysfunction. Efforts, in order to implement educative strategies for healthy lifestyle, should be addressed.

Abstract
INTRODUCTION Erectile dysfunction (ED) has been significantly associated with many chronic conditions including obesity, the metabolic syndrome, hypogonadism, diabetes mellitus, cardiovascular disease (CVD), lower urinary tract symptoms, and psychiatric/psychological disorders. ED is also a well-established predictor of CVD. AIM This review will focus on the association of ED with cardiovascular, metabolic, and cognitive conditions and discuss the effects of managing lifestyle factors in order to reduce the burden of ED and consequently outcomes in patients with chronic conditions. METHODS A literature search using Medline, PubMed (U.S. National Library of Medicine and the National Institutes of Health), and abstracts from scientific meetings was performed from 1990. MAIN OUTCOME MEASURES Main outcome measures were improvements in sexual function. RESULTS A total of 59 reviews on the topic were evaluated. CONCLUSIONS Targeting several lifestyle factors associated with CVD/metabolic/cognitive disorders, e.g., smoking, alcohol consumption, obesity, and physical activity, can have significant benefits, leading to an improvement in ED as well as testosterone levels and consequently CVD.

Abstract
The aim of this study was to evaluate the prevalence of erectile dysfunction (ED) in a cohort of Italian hypertensive men and the association with clinical and biochemical data. The study involved 270 consecutive hypertensive subjects aged 40-70 years evaluated in Italian Hypertension Centers of six hospitals from Liguria and Piedmont. ED was assessed through the self-administered questionnaire of the International Index of Erectile Function. Clinical history with ongoing drug treatment, various clinical parameters, biochemical data and evidence about the presence of subclinical target organ damage was collected. Twenty-seven subjects refused to answer the questionnaire (10%). Among the 243 remained subjects, 123 presented ED (50.6%). ED was highly related to age, systolic blood pressure, pulse pressure, smoking status, statin therapy and kidney function. The addition of a thiazide diuretic to an inhibitor of the renin-angiotensin system significantly increased the prevalence of ED. The prevalence of ED increased in relation with the number of hypotensive drug classes taken by the patients. ED was highly prevalent in this cohort of Italian hypertensive subjects and was associated with other cardiovascular risk factors, such as age, smoking status and kidney function. The role of ED as an early marker of cardiovascular disease is discussed.

Abstract
BACKGROUND Symptoms of depression are common in patients diagnosed with benign prostatic hyperplasia (BPH) and are usually a reaction to deterioration of health, severity of lower urinary tract symptoms, and erectile dysfunction. The aim of this observational study was to evaluate the prevalence of depressive symptoms in patients diagnosed with BPH and factors affecting their occurrence in a large Polish cohort. PATIENTS AND METHODS Four thousand thirty-five men (4,035) diagnosed with BPH participated in the survey (age 65 ± 8 years). The occurrence of symptoms of depression was assessed using the Beck depression inventory, severity of lower urinary tract symptoms (LUTS) on the basis of the international prostate symptoms score, and erectile dysfunction using the international index of erectile function (IIEF-5). RESULTS Depressive symptoms were found in 22.4% of patients (mild in 20.8% and moderate/severe in 1.6%). Erectile dysfunction was found in 71.9% of patients. Monotherapy for BPH was prescribed to 50.9% of patients (mostly ARA-selective α1-selective alpha-adrenolytic-47.5%), while polytherapy (ARA with a 5-alpha reductase inhibitor-5αRI) to 47.9%. Logistic regression analysis showed a bidirectional relation between the occurrence of depressive symptoms and erectile dysfunction. The occurrence of both depressive symptoms and erectile dysfunction was related to severity of LUTS, nocturia, the use of 5αRI, comorbidity, and sedentary life style. CONCLUSIONS Prevalence of depressive symptoms in patients diagnosed with BPH is associated with severity of LUTS, erectile dysfunction, nocturia, BPH pharmacotherapy (5αRIs), sedentary life style, and comorbidities including obesity.

Abstract
BACKGROUND Men who have sex with men (MSM) remain the group most affected by the HIV epidemic in the United States. At least one-quarter of MSM report engagement in group sex events (GSEs), which can pose a risk for HIV transmission and acquisition. In this study, identification of event-level correlates of sexual and drug use behaviours at GSEs was sought to better inform prevention activities. METHODS For this study, participants were recruited via banner and pop-up advertisements placed on a geosocial networking mobile phone application that MSM use to meet men. RESULTS Of the 1997 individuals who completed the study screener, 36.0% reported participating in at least one GSE in the prior year. In multivariable logistic regression analysis, attendance at a GSE in the past year was significantly associated with older age, full/part time employment and being HIV positive. Of the men who attended a GSE, more than half reported condomless anal sex (CAS) with at least one of their partners (insertive: 57.7%; receptive: 56.3%). MSM who indicated drug use had significantly higher odds of having insertive CAS [odds ratio (OR)=2.45; 95% confidence interval (CI): 1.37-4.39] and receptive CAS (OR=3.60; 95% CI: 1.96-6.63) at their last GSE. CONCLUSIONS The high prevalence of HIV-positive MSM engaging in group sex, coupled with their greater odds of CAS, poses a significant risk for HIV/STI transmission within the group sex setting. More research is needed to determine patterns of condom use at these events and whether seroadaptive behaviours are driving CAS.

Abstract
There are limited numbers of studies which have evaluated the sexual dysfunction (SD) in patients with alcohol and opioids dependence. This article reviews the existing literature. Electronic searches were carried out using the PubMed, Google Scholar, and ScienceDirect to locate the relevant literature. Subjects addicted to heroin or on methadone maintenance treatment (MMT) or buprenorphine maintenance treatment (BMT) show higher rates of SD in comparison to the general population. SD rates have ranged 34-85% for heroin addicts, 14-81% for MMT, 36-83% for BMT, and 90% for naltrexone maintenance. The rates of SD in alcohol-dependent population have ranged 40-95.2%, with rates being consistently much higher in alcohol-dependent population than in the healthy controls or social drinkers. The common SDs reported have been erectile dysfunction followed by premature ejaculation, retarded ejaculation and decreased sexual desire among men, and dyspareunia and vaginal dryness among women. This review suggests that long-term use of alcohol and opioids are associated with SD in almost all domains of sexual functioning. There is a need to increase the awareness of clinicians about this association as many times SD in patients with substance abuse lead to poor treatment compliance and relapse. Further, there is a need to carry out more number of studies to understand the relationship in a better way.

Abstract
Introduction. Substance use disorders (SUDs) are commonly associated with a variety of psychiatric disorders. Community-based studies have found a significant association between SUDs and sexual dysfunction in men, with a possible causal relation in the case of nicotine. Methods. The case records of 105 men presenting to a clinic for patients with psychosexual disorders were reviewed. Men with and without comorbid SUDs were compared in terms of demographic, clinical, and familial variables. Results. 25 of the 105 men (23.8%) had a lifetime diagnosis of SUD, and 19 (18.1%) had a current SUD. The commonest substances involved were nicotine (n = 21, 20%) and alcohol (n = 9, 9.5%). Men with comorbid SUDs were more likely to report a family history of substance dependence, particularly alcoholism. Single men with SUDs were more likely to have a comorbid mood disorder. Conclusion. SUDs, particularly nicotine and alcohol use disorders, are common comorbidities in patients with psychosexual disorders. Identifying and treating these disorders in this population are important aspects of management.

Abstract
Erectile dysfunction (ED) is the most common male sexual problem worldwide. The association between ED and components of metabolic syndrome (MtS) is well established. This study examined neck circumference (NC) as a possible indicator of MtS and also of ED. Ninety-two patients were included and divided into two groups. Group 1 consisted of 47 patients with ED and Group 2 consisted of 45 healthy volunteers. Questionnaires, differences in anthropometric and laboratory measurements between patients with ED and the control group, and a cut-off value for NC were investigated. The mean NC in ED patients was higher in Group 1 than in Group 2 (P = 0.001), and Group 1 also demonstrated more MtS criteria than Group 2 (P < 0.001). The cut-off point of NC was defined as 34.75 cm for ED and MtS. The cut-off values of waist circumference for ED and MtS were 105.5 and 102.5 cm respectively. In the light of these findings, NC may be a new component of MtS in ED patients. Additionally, NC may be a novel indicator of central obesity and ED. We suggest that NC values of 35 cm and over may predict ED in patients with MtS.

Moyad MA, Park K. What do most erectile dysfunction guidelines have in common? No evidence-based discussion or recommendation of heart-healthy lifestyle changes and/or Panax ginseng. Asian J Androl 2012; 14:830-41.

Abstract
Sexual health or erectile dysfunction (ED) state of the art guidelines provide a thorough overview of conventional prescription or other notable extrinsic treatment options. Yet, over the past 10-15 years, a plethora of international researchers have established that individual and comprehensive lifestyle changes can prevent and potentially improve ED. We review the lifestyle evidence that should equate to grade A or level 1 evidence recommendations for ED. We also review the evidence for Panax ginseng, an over-the-counter (OTC) dietary supplement with a 35-year history of laboratory investigations, multiple positive randomized trials over approximately 15 years and several independent meta-analyses and systematic reviews. Perhaps it is time to at least discuss and even emphasize lifestyle and other non-conventional interventions in ED guidelines so that patients can explore a diversity of potentially synergistic choices with their physicians and can improve their quality and quantity of life. Ignoring the consistent, positive data on lifestyle modifications in ED guidelines, for example, is tantamount to ignoring diet and lifestyle changes to reduce the risk of or ameliorate cardiovascular diseases.

Effects of male silkworm pupa powder on the erectile dysfunction by chronic ethanol consumption in rats. Lab Anim Res 2012; 28:83-90.

Abstract
Erectile dysfunction (ED) is a highly prevalent disorder that affects millions of men worldwide. ED is now considered an early manifestation of atherosclerosis, and consequently, a precursor of systemic vascular disease. This study was designed to investigate the effects of male silkworm pupa powder (SWP) on the levels of nitric oxide synthase (NOS) expression, nitrite, and glutathione (GSH); lipid peroxidation; libido; and erectile response of the corpus cavernosum of the rat penis. We induced ED in the study animals by oral administration of 20% ethanol over 8 weeks. The SWP-treated male rats were divided into 3 groups that were orally administered 200, 400, and 800 mg/kg. The libido of the SWP-administered male rats was higher than that of the ethanol control group. In addition, the erectile response of the corpus cavernosum was restored in males on SWP administration, to a level similar to that of the normal group without ED. The testosterone concentration did not increase significantly. The lipid peroxidation in the corpus cavernosum of the male rats administered SWP decreased significantly. In contrast, compared to the ethanol group, SWP-administered male rats showed increased GSH levels in the corpus cavernosum. The level of nitrite and NOS expression in the corpus cavernosum of SWP-administered male rats increased significantly. These results indicated that SWP effectively restored ethanol-induced ED in male rats.

Abstract
INTRODUCTION Erectile dysfunction (ED) is usually associated with systemic disorders. This population-based study supports and expands on previous research. It also presents data in a Taiwanese male population where existing data on this topic remain sparse. AIM The aim of this study is to analyze the prevalence and risk of 36 medical comorbidities in patients with ED compared with the general population. METHODS A total of 2,213 patients with ED and 11,065 matching controls were selected from the Taiwan National Health Insurance Research Dataset. We chose 22 comorbidities from the Elixhauser comorbidity index, 10 highly prevalent medical conditions in an Asian population, and four male gender-specific comorbidities for analysis. MAIN OUTCOME MEASUREMENT Conditional logistic regression analyses conditioned on age group and monthly income were performed to investigate the risk of various comorbidities for patients with and without ED, after adjusting for the geographic region and level of urbanization of the patient's community. RESULTS Patients with ED were at an increased risk for multiple systemic comorbidities. Conditional regression analyses showed that patients with ED were at a higher risk for hypertrophy of the prostate (odds ratio [OR] = 12.87), chronic prostatitis (OR = 9.36), alcohol abuse (OR = 3.60), drug abuse (OR = 2.62), urinary incontinence (OR = 2.58), ankylosing spondylitis (OR = 2.19), peripheral vascular disorder (OR = 1.98), ischemic heart disease (OR = 1.94), psychoses (OR = 1.97), depression (OR = 1.88), uncomplicated diabetes (OR = 1.91), complicated diabetes (OR = 1.84), hepatitis B or C (OR = 1.71), hyperlipidemia (OR = 1.69), and chronic pulmonary disease (OR = 1.55) than patients without ED. CONCLUSION The results show that patients with ED have a higher prevalence of multiple noncardiovascular comorbidities than the general population in Taiwan.

Abstract
Lifestyle and nutrition have been increasingly recognized as central factors influencing vascular nitric oxide (NO) production and erectile function. This review underscores the importance of NO as the principal mediator influencing cardiovascular health and erectile function. Erectile dysfunction (ED) is associated with smoking, excessive alcohol intake, physical inactivity, abdominal obesity, diabetes, hypertension, and decreased antioxidant defenses, all of which reduce NO production. Better lifestyle choices; physical exercise; improved nutrition and weight control; adequate intake of or supplementation with omega-3 fatty acids, antioxidants, calcium, and folic acid; and replacement of any testosterone deficiency will all improve vascular and erectile function and the response to phosphodiesterase-5 inhibitors, which also increase vascular NO production. More frequent penile-specific exercise improves local endothelial NO production. Excessive intake of vitamin E, calcium, l-arginine, or l-citrulline may impart significant cardiovascular risks. Interventions discussed also lower blood pressure or prevent hypertension. Certain angiotensin II receptor blockers improve erectile function and reduce oxidative stress. In men aged <60 years and in men with diabetes or hypertension, erectile dysfunction can be a critical warning sign for existing or impending cardiovascular disease and risk for death. The antiarrhythmic effect of omega-3 fatty acids may be particularly crucial for these men at greatest risk for sudden death. In conclusion, by better understanding the complex factors influencing erectile and overall vascular health, physicians can help their patients prevent vascular disease and improve erectile function, which provides more immediate motivation for men to improve their lifestyle habits and cardiovascular health.

Abstract
Sexual problems are diffuse in both genders. Although epidemiologic evidence seems to support a role for lifestyle factors in erectile dysfunction, limited data are available suggesting the treatment of underlying risk factors may improve erectile dysfunction. The results are sparse regarding associations between lifestyle factors and female sexual dysfunction, and conclusions regarding influence of healthy behaviors on female sexual dysfunction cannot be made before more studies have been performed. Beyond the specific effects on sexual dysfunctions in men and women, adoption of these measures promotes a healthier life and increased well-being, which may help reduce the burden of sexual dysfunction.
