Abstract
Torilis japonica (TJ) fruit, is a herb that is traditionally used for erectile dysfunction (ED). Given the shared mechanisms of ED and hypertension through vascular smooth muscle, we hypothesized that TJ would be effective in vasodilation and blood pressure reduction. This study confirmed the authenticity of TJ samples via DNA barcoding and quantified the main active compound, torilin, using HPLC. TJ was extracted with distilled water (TJW) and 50% ethanol (TJE), yielding torilin contents of 0.35 ± 0.01% and 2.84 ± 0.02%, respectively. Ex vivo tests on thoracic aortic rings from Sprague-Dawley rats showed that TJE (3-300 µg/mL) induced endothelium-independent, concentration-dependent vasodilation, unlike TJW. Torilin caused concentration-dependent relaxation with an EC50 of 210 ± 1.07 µM. TJE's effects were blocked by a voltage-dependent K+ channel blocker and alleviated contractions induced by CaCl2 and angiotensin II. TJE inhibited vascular contraction induced by phenylephrine or KCl via extracellular CaCl2 and enhanced inhibition with nifedipine, indicating involvement of voltage-dependent and receptor-operated Ca2+ channels. Oral administration of TJE (1000 mg/kg) significantly reduced blood pressure in spontaneously hypertensive rats. These findings suggest TJ extract's potential for hypertension treatment through vasorelaxant mechanisms, though further research is needed to confirm its efficacy and safety.

Abstract
INTRODUCTION The present study aimed at investigating the effect of dietary supplementation of Phoenix dactylifera, an important component of aphrodisiac supplements, on sexual performance, oxido-inflammatory mediators and purinergic signaling system in hypertensive rats. MATERIAL AND METHODS Hypertension was induced via oral administration of 40 mg/kg L-NAME. Thereafter, the sexual performance of the experimental animals was determined and the hypertensive rats with impaired sexual activities were placed on P. dactylifera-supplemented diet for 21 days, and the effects of the treatment on the overall sexual behavior, antioxidant status, oxido-inflammatory biomarkers, and enzyme activity of the purinergic system were assessed. RESULTS Hypertensive rats showed a significant (p < 0.05) decrease in sexual performance, elevated level of oxido-inflammatory mediators, and altered purinergic enzymes activity when compared with the control. However, sub-chronic feeding with P. dactylifera-supplemented diet improved sexual performance, significantly lowered oxido-inflammatory biomarkers, and enhanced the activity of purinergic enzymes in hypertensive rats. CONCLUSION Findings presented in this study suggest that dietary inclusion of P. dactylifera could be useful in managing erectile dysfunction (ED) commonly observed in subjects with hypertension. Findings highlighted in this study thus provide the scientific basis supporting the folkloric use of P. dactylifera as a key ingredient in aphrodisiac supplements.

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
INTRODUCTION Erectile dysfunction (ED) poses a significant disease morbidity and contributor to male infertility, where an estimated 20-40% of men are affected annually. While several risk factors have been identified in the etiology of ED (e.g., aging, heart disease, diabetes, and obesity), the complete pathogenesis remains to be elucidated. Over the last few decades, the contribution of environmental exposures to the pathogenesis of ED has gained some attention, though population studies are limited and results are mixed. Among environmental contaminants, organophosphate (OP) insecticides represent one of the largest chemical classes, and chlorpyrifos is the most commonly used OP in the U.S. OP exposure has been implicated in driving biological processes, including inflammation, reactive oxygen species production, and endocrine and metabolism disruption, which have been demonstrated to adversely affect the hypothalamus and testes and may contribute to ED. Currently, studies evaluating the association between OPs and ED within the U.S. general population are sparse. METHODS Data were leveraged from the National Health and Nutrition Examination Survey (NHANES), which is an annually conducted, population-based cross-sectional study. Urinary levels of 3,5,6-trichloro-2-pyridinol (TCPy), a specific metabolite of the most pervasive OP insecticide chlorpyrifos, were quantified as measures of OP exposure. ED was defined by responses to questionnaire data, where individuals who replied "sometimes able" or "never able" to achieve an erection were classified as ED. Chi-square, analysis of variance (ANOVA), and multivariable, weighted linear and logistic regression analyses were used to compare sociodemographic variables between quartiles of TCPy exposure, identify risk factors for TCPy exposure and ED, and to analyze the relationship between TCPy and ED. RESULTS A total of 671 adult men were included in final analyses, representing 28,949,379 adults after survey weighting. Approximately 37% of our cohort had ED. Smoking, diabetes, aging, Mexican-American self-identification, and physical inactivity were associated with higher ED prevalence. Analysis of TCPy modeled as a continuous variable revealed nonsignificant associations with ED (OR = 1.02 95% CI [0.95, 1.09]). Stratification of total TCPy into quartiles revealed increased odds of ED among adults in the second and fourth quartiles, using the first quartile as the reference (OR = 2.04 95% CI [1.11, 3.72], OR = 1.51 95% CI [0.58, 3.93], OR = 2.62 95% CI [1.18, 5.79], for quartiles 2, 3, and 4, respectively). CONCLUSIONS The results of our study suggest a potential role for chlorpyrifos and other OPs the pathogenesis of ED. Future studies are warranted to validate these findings, determine clinical significance, and to investigate potential mechanisms underlying these associations.

Abstract
BACKGROUND Research on the relationship between posttraumatic stress disorder (PTSD) and sexual dysfunctions (SD) has clearly recognized the association among these conditions. The main objective of this research was to compare the levels of the overall and the level of certain domains of sexual functioning among veterans with and those without PTSD. METHODS Two hundred and fifty veterans with PTSD and 187 veterans without PTSD were included in the comparative study. The following assessments were conducted: LEC-5, PCL-5, ITQ, IIEF, PEDT, and MINI. RESULTS Veterans with PTSD had significantly higher levels of all types of SD in the PTSD group compared with the non-PTSD veterans. Veterans with PTSD more frequently experienced psychiatric and somatic comorbidities and use of medication that may contribute to the occurrence and severity of SD. CONCLUSIONS The present study emphasized that SDs are an important issue among patients with PTSD. The study comprehensively accounted for conditions that may contribute to the occurrence and severity of SD among veterans with PTSD. Future directions of the research that could further improve the healthcare of the patients were indicated.

Abstract
Background Erectile dysfunction (ED) is a common sexual problem that profoundly affects intimate relationships. It is poorly studied in North-western Nigeria. Objectives To assess the prevalence, severity and predictors of ED among adult males attending a primary care clinic in Northwest Nigeria. Methods A cross-section of 392 males (aged ≥25 years) were randomly selected from attendees of a family medicine clinic in Kano, Nigeria. Information regarding their biodata, lifestyle factors, and clinical characteristics was obtained using a structured questionnaire. The International Index of Erectile Function Questionnaire (version 5) and Patient Health Questionnaire-2 assessed ED and depression, respectively. Results The participants' mean age was 45±14.1 years (range: 26-86 years). Most participants were married (88.8%), had one sexual partner (71.7%), had tertiary education (44.4%) and were traders (49.7%). The prevalence of ED was 52.3% (205/392) [comprising mild (36.0%), mild-to-moderate (14.3%), moderate (1.5%) and severe (0.5%)]. Age, body mass index (BMI), marital status, number of sexual partners, monthly income, type of exercise, hypertension history, blood pressure reading, antihypertensive and peptic ulcer drug use were associated with ED (P<0.05). However, age (≥50years) (OR= 1.91, 95%CI [1.28-2.85], P=0.001) and overweight/obesity (OR =1.81, 95%CI [1.18-2.77], P=0.007) were the predictors of ED in this population. Conclusion ED prevalence was high, although mainly of the mild form. Age (≥50years) and overweight/obesity predicted ED. Hence, the need for early screening, objective grading of ED, identification of modifiable risk factors (e.g., overweight/obesity) and commencing proper treatment and prevention in this setting.

Abstract
Twelve drugs containing sildenafil compounds (sildenafil citrate and sildenafil base) were examined using X-ray studies and thermal analysis. According to the manufacturer’s information, the presence of sildenafil was confirmed in all investigated drugs. The positions of diffraction lines (value of 2θ angle) agree with the patterns presented in the ICDD database, Release 2018 (ICDD—International Centre of Diffraction Data). The difference expresses the agreement in the position of the diffraction line between the tested substance and the standard. A good agreement is when this difference is less than 0.2°. The values of interplanar distances dhkl are also compatible with the ICDD database. It indicated that the drug examined was genuine. Because all drugs are mixtures of different substances (API and excipients), the various diffraction line intensities were detected in all observed X-ray images for the tested drugs. The intensity of the diffraction line depends on many factors, like the amount of substance, coexisting phases, and mass absorption coefficient of the mixture. The thermal analysis confirmed the results obtained by the X-ray study. On DSC curves, the endothermic peaks for sildenafil compounds were observed. The determined melting points of sildenafil compounds corresponded to the values available in the literature. The results gathered by connecting two methods, X-ray study and thermal analysis, can help identify irregularities that may exist in pharmaceutical specimens, e.g., distinguishing genuine from counterfeit products, the presence of a correct polymorph, a lack of active substance, an inaccurate amount of the active substance, or excipients in the tested drug.

Abstract
PURPOSE The role of erectile dysfunction (ED) has recently shown an association with the risk of stroke and coronary heart disease (CHD) via the atherosclerotic pathway. Cardiovascular disease (CVD)/stroke risk has been widely understood with the help of carotid artery disease (CTAD), a surrogate biomarker for CHD. The proposed study emphasizes artificial intelligence-based frameworks such as machine learning (ML) and deep learning (DL) that can accurately predict the severity of CVD/stroke risk using carotid wall arterial imaging in ED patients. METHODS Using the PRISMA model, 231 of the best studies were selected. The proposed study mainly consists of two components: (i) the pathophysiology of ED and its link with coronary artery disease (COAD) and CHD in the ED framework and (ii) the ultrasonic-image morphological changes in the carotid arterial walls by quantifying the wall parameters and the characterization of the wall tissue by adapting the ML/DL-based methods, both for the prediction of the severity of CVD risk. The proposed study analyzes the hypothesis that ML/DL can lead to an accurate and early diagnosis of the CVD/stroke risk in ED patients. Our finding suggests that the routine ED patient practice can be amended for ML/DL-based CVD/stroke risk assessment using carotid wall arterial imaging leading to fast, reliable, and accurate CVD/stroke risk stratification. SUMMARY We conclude that ML and DL methods are very powerful tools for the characterization of CVD/stroke in patients with varying ED conditions. We anticipate a rapid growth of these tools for early and better CVD/stroke risk management in ED patients.

Diabetes associated with hypertension exacerbated oxidative stress-mediated inflammation, apoptosis and autophagy leading to erectile dysfunction in rats. J Chin Med Assoc 2022; 85:346-357.

Abstract
BACKGROUND Diabetes or hypertension contributes to erectile dysfunction (ED). We hypothesized that excess reactive oxygen species (ROS) production evoked by diabetes combined with hypertension may further suppress endothelial nitric oxide (NO) expression/activity and promote oxidative stress in the ED penis. METHODS Twenty-four adult male Wistar Kyoto rats (WKY) and spontaneously hypertensive rats (SHR) were divided into four groups: normal WKY, diabetic WKY, normal SHR and diabetic SHR. Intraperitoneal streptozotocin (65 mg/kg) was applied to induce type I diabetes. After 4-week diabetes and/or hypertension induction, we determined the intra-cavernous pressure (ICP) using electrical stimulation of cavernous nerves, intra-cavernosum NO amount using an electrochemical NO probe, and blood ROS using an ultrasensitive chemiluminescence-amplified analyzer. Western blot analysis and immunohistochemistry were used to explore the pathophysiologic mechanisms of inflammation, apoptosis and autophagy in the penis. A novel NO donor, CysaCysd Lu-5 (CCL5, (RCH2CH2S)(R'R"CHCH2S)Fe(NO)2, 1-4 µg), was intravenously administered to these ED rats for evaluating their ICP responses. RESULTS In the baseline status, the lucigenin- and luminol-amplified blood ROS were significantly enhanced in the diabetic SHR rats vs normal WKY rats. Significantly decreased ICP, eNOS expression and NO amount were found in the normal SHR, diabetic WKY, and diabetic SHR vs normal WKY rats. Intravenous NO donor L-Arginine markedly increased ICP and NO amount, whereas eNOS inhibitor, Nω-Nitro-L-Arginine methyl ester hydrochloride depressed ICP in all four groups. Diabetes and/or hypertension alone increased fibrosis, proinflammatory NF-kB/ICAM-1 expression, mast cell numbers, CD68 expression and infiltration, Caspase 3-mediated apoptosis, Beclin-1/LC3-II-mediated autophagy and mild Nrf-2/HO-1 expression and depressed eNOS expression in the ED penis. The novel NO donor, CCL5, was more efficient than L-arginine to improve diabetes and/or hypertension-induced ED by the significant increase of ICP. CONCLUSION Diabetes combined with hypertension synergistically exacerbated ED through enhanced oxidative stress, inflammation, apoptosis and autophagy and depressed eNOS activity and NO production.

Abstract
BACKGROUND Substance use may affect sexual functioning in both men and women. Comorbid sexual dysfunction adds to the clinical burden of substance use disorders (SUD). AIMS The broad aims were to identify research conduct, types of the available evidence, and research gaps in (i) estimating the incidence, prevalence, type, and severity of sexual dysfunction in adults with SUD; (ii) exploring correlates of sexual dysfunction in SUD. METHODS We conducted systematic searches on PubMed, Google Scholar, and Embase for studies published in the English language between August 1954 and November 2020. We included prospective and cross-sectional observational studies that had examined the prevalence or incidence of any sexual dysfunction in adults of either gender with substance use disorders. Review articles and those with an exclusive focus on tobacco use disorders were excluded. The review was registered in PROSPERO. RESULTS Our search identified 65 relevant articles, including five prospective studies. All the prospective studies and most of the cross-sectional studies (n = 40) were done among men and subjects with alcohol (n = 20) and opioid (n = 23) use disorders in clinical populations. Substance use and sexual dysfunction were assessed by a wide range of instruments. Prospective studies reported a prevalence of sexual dysfunction at 75% and 61% for alcohol and opioid use disorders, respectively. The prevalence of any sexual dysfunction in cross-sectional studies ranged between 15 and 100 percent. Erectile dysfunction was the most commonly studied and observed sexual dysfunction. Comorbidity and socioeconomic deprivation were consistently associated with a higher occurrence of sexual dysfunctions. STRENGTHS We did not limit our review by the type of substances and year of publication. We adhered to the standards of conducting and reporting scoping reviews; hence, our review results should be replicable, transparent, and reliable. LIMITATIONS The wide clinical and methodological heterogeneity precluded a systematic review. CONCLUSION Research gaps exist in women, non-clinical population, stimulants, and cannabis use disorders, and effect of treatment of SUD in sexual functioning. The quality of evidence is poor.

Int J Hypertens 2021; 2021:1482500. [PMID: 34868672 PMCID: PMC8642021 DOI: 10.1155/2021/1482500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Accepted: 11/11/2021] [Indexed: 12/04/2022] Open
Abstract
Introduction Erectile dysfunction is a common sexual problem affecting men with hypertension. It may result in withdrawal from sexual engagement, decreased work productivity, psychosocial problems including poor self-esteem and depression, and reduction in quality of life for both the affected men and their female partners. Objective This study was aimed to determine the prevalence of erectile dysfunction and associated factors among hypertensive patients attending governmental health institutions in Gondar city, Northwest Ethiopia. Materials and Methods An institutional-based cross-sectional study was conducted on 423 hypertensive men randomly selected using a systematic random sampling technique. Erectile dysfunction was assessed using the International Index of Erectile Function-5 tool. Sociodemographic, clinical, and behavioral factors were also collected using pretested interviewer-administered questionnaires. Data were entered into EpiData version 4.6 and analyzed using Stata-14. Binary logistic regression was performed to identify factors associated with erectile dysfunction. The level of significance was computed at a p value ≤ 0.05. Results The mean age of the study participants was 58.84 ± 13.52 years. The prevalence of erectile dysfunction among hypertensive men was 46.34% (95% CI: 41.61, 51.12). About 28% of them had a mild form of erectile dysfunction while nearly 6% had severe forms. Age above 60 years (AOR = 3.8, 95% CI: 1.62, 6.55), stage II hypertension (AOR = 3.5, 95% CI: 1.63, 5.74), hypertension duration >10 years (AOR = 2.5, 95% CI:1.12, 4.19), comorbidity (AOR = 1.7, 95% CI: 1.04, 3.15), depression (AOR = 2.35, 95% CI: 1.31, 4.21), and being physically active (AOR = 0.48, 95% CI: 0.28, 0.83) were factors significantly associated with erectile dysfunction. Conclusion Nearly half of the study participants had some form of erectile dysfunction, indicating the presence of a high burden of the problem. Assessment of hypertensive men for erectile dysfunction should be part of routine medical care.

Abstract
Introduction Phosphodiesterase 5 inhibitors are the predominant treatment option for erectile dysfunction. Aim This study evaluates the efficacy and safety of sildenafil orally disintegrating strips for the treatment of erectile dysfunction. Methods One hundred twenty erectile dysfunction patients were enrolled in a prospective, randomized, controlled crossover study and allocated into 2 groups of 60 participants. Patients were either treated with sildenafil strips or tablets for 8 weeks after which they crossed over into the alternate treatment formulation for another 8 weeks following a 4-week wash-out period. Each participant was assessed 8 times throughout the study period and their formulation preference registered at the end of the study. Main outcomes and measures Changes in the abridged International Index of Erectile Function (IIEF-5) score and Erection Hardness Score (EHS) resulting from sildenafil orally disintegrating strip or tablet treatments were the primary end points, with differences in onset of action, duration of action, and incidence of adverse events between the 2 formulations included as secondary end points. Results Both sildenafil formulations were effective in treating patients with erectile dysfunction. There was significant improvement of erectile function in term of IIEF-5 score and EHS from both formulations. The number and type of adverse events were also comparable. Likewise, there were no statistically significant differences between the earliest onset of action times and longest duration of action times. However, the results showed a 7.1-minute earlier onset of action time for orally disintegrating strips that may be considered as clinically meaningful by some patients. Conclusion Sildenafil orally disintegrating strips are a safe and effective alternative to the conventional tablet formulation for the treatment of erectile dysfunction.

Abstract
Objectives This study aims to explore the prevalence of sexual satisfaction among Chinese cancer survivors, and explore the association of sexual satisfaction with comorbidity and lifestyle factors. Methods A cross‐sectional study was performed among 3996 Chinese cancer survivors recruited at Shanghai Cancer Rehabilitation Club from March to April 2017. Data were collected through self‐reported questionnaires. The questionnaire includes information about demographic, cancer characteristics, comorbidities, lifestyle factors, and sexual satisfaction. Sexual satisfaction was measured by a single‐item scale. The distribution of sexual satisfaction among different demographic and cancer characteristics was compared using the chi‐squared test. Logistic regression models were conducted to assess the effects of lifestyle factors, comorbidities on sexual satisfaction after adjustment for demographic and cancer characteristics. Results More than 40% of male and female cancer survivors reported no sexual satisfaction. Sexual satisfaction of cancer survivors is significantly associated with both the number and the type of comorbidities. Heart disease, musculoskeletal system disease, diabetes, and hyperlipidemia are the comorbidities significantly associated with sexual satisfaction of cancer survivors. Lifestyle factors other than smoking, including exercise or fitness, drinking alcohol, and eating fruits and vegetables are significantly correlated with sexual satisfaction. Besides, all of the above associations show gender differences. In addition, demographic characteristics include sex, age, marital status, living status, and average monthly income are also significantly associated with sexual satisfaction of cancer survivors. Conclusion Comorbidity and lifestyle factors are associated with sexual satisfaction of cancer survivors, and the associations show gender differences. Improving the lifestyles of cancer survivors, and controlling and reducing their comorbidities are important for improving their sexual satisfaction. This study aims to investigate the prevalence of sexual satisfaction among Chinese cancer survivors, and explore the association of sexual satisfaction with comorbidity and lifestyle factors. Comorbidity and lifestyle factors are associated with sexual satisfaction of cancer survivors, and the associations show gender differences. Improving the lifestyles of cancer survivors, and controlling and reducing their comorbidities are important for improving their sexual satisfaction.

Abstract
BACKGROUND Hypertension (HPT) is an essential public health problem affecting both lower and middle-income countries disproportionately. Evidence suggests that HPT is the leading risk factor for cardiovascular diseases and chronic kidney disease. Yet, challenges faced by patients with HPT in Ghana are not sufficiently explored. This study, documents the challenges patients with HPT face in Ghana. METHODS We used an explorative descriptive qualitative design. Face-to-face in-depth interviews were conducted with 15 patients with HPT. Interviews were recorded and transcribed verbatim. A thematic content analysis procedure was followed to analyse the data. RESULTS Four main themes emerged from interviews; three of which pertained to dimensions of challenges and a fourth which pertained to coping strategies. These include: [1] impairment in physical activities and mobility constraints [2]. Psychological challenges such as suicidal ideations, sadness, fear, anxiety, and reduced sexual affection [3]. Socio-economic challenges identified include loss of friends and social network, difficulty in job demands, and financial burden, and [4] coping strategies such as health system support, social support, and religiosity were identified. CONCLUSION Patients with HPT experience an array of challenges. We suggest that health care facilities incorporate post HPT diagnosis counseling sessions for HPT patients in the study area. Also, the National Health Insurance Authority (NHIA) should re-examine their scope of services; thus, drugs, laboratory services, and electrocardiogram services to avoid the issue of co-payment. Collaboration between healthcare professionals and family relations of patients with HPT ought to also be strengthened to ensure optimal care.

Effects of chronic type 5 phosphodiesterase inhibition on penile microvascular reactivity in hypertensive patients with erectile dysfunction: a randomized crossover placebo-controlled trial. J Hum Hypertens 2021; 35:360-370. [PMID: 32366927 DOI: 10.1038/s41371-020-0343-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 04/14/2020] [Accepted: 04/21/2020] [Indexed: 01/29/2023]
Abstract
This randomized crossover and placebo-controlled trial evaluated the effects of daily use of sildenafil citrate (SIL, 1-month 50 mg twice daily) on penile and systemic endothelial microvascular function in hypertensive patients presenting with erectile dysfunction. The effects of SIL on arterial pressure were evaluated using ambulatory blood pressure monitoring (ABPM). Fifty patients diagnosed with primary arterial hypertension and erectile dysfunction (aged 57.4 ± 5.6 years), recruited in a tertiary public hospital, were treated with SIL (50 mg twice daily) or placebo (PLA) for two 30-day periods with a 30-day washout between them. Laser speckle contrast imaging coupled with acetylcholine skin iontophoresis was used to evaluate penile and systemic (forearm) cutaneous microvascular reactivity. SIL treatment increased penile basal microvascular flow (P = 0.002) and maximal endothelial-dependent peak response to skin iontophoresis of acetylcholine (ACh, P = 0.006). The area under the curve of microvascular vasodilation induced by ACh was also significantly increased (P = 0.02). Lastly, SIL treatment did not modify systemic microvascular reactivity. Twenty-four-hour ABPM (P = 0.0002) and daytime (P = 0.002) and nighttime (P = 0.001) mean diastolic blood pressure values were significantly reduced after SIL treatment. The scores of the Simplified International Index of Erectile Function (P < 0.0001) and the number of patients with positive responses to Sexual Encounter Profile question 3 (P < 0.0001) also increased after SIL treatment. Penile endothelium-dependent microvascular reactivity improved after continuous use of sildenafil in hypertensive patients with erectile dysfunction; the treatment also reduced blood pressure, suggesting that, in addition to improving erectile function, daily use of sildenafil could improve blood pressure control.

Abstract
Introduction Hypertension is a very common risk factor for erectile dysfunction (ED). In recent time, changes in lifestyle has led to an increase in the prevalence of hypertension, which has increased the risk of ED. The purpose of this study is to assess the prevalence of ED in hypertensive patients and compare various domains of sexual activity between hypertensive and normotensive participants. Methods This case-control study was conducted in an outpatient department of a tertiary health care hospital in Pakistan from March 2019 to September 2019. Two hundred and twelve clinically diagnosed hypertensive patients were enrolled and were identified as case group. Control group consisted of 212 people, without any history of hypertension. Sexual function was assessed with the International Index of Erectile Function (IIEF). Results The prevalence of erectile dysfunction in hypertensive group was 61.79%, compared to 20.28% in normotensive group. Erectile weakness (OR = 4.32, CI 2.64-7.05), impaired morning erection (OR = 5.02, CI 2.98-8.47), complete erectile failure (OR = 2.32, CI 1.14-4.75), impaired spontaneous erection (OR = 5.45, CI 3.28-9.03), ejaculatory disturbances (OR = 5.20, CI 2.96-9.12) and reduced sexual interest (OR = 5.12, CI 3.04-8.64) were found to be significantly higher in patients with hypertension compared to normotensive participants. Conclusion This study has found ED to be prevalent in hypertensive patients. Identifying and acknowledging hypertension as a risk factor may help identify patients with ED and reinforce the clinician's importance of asking sexual history of hypertensive patients.

Abstract
Objective This small scale cross-sectional study was done to identify the common systolic blood pressure pattern (dipping or non-dipping) among type 2 diabetic men with coexisting hypertension and erectile dysfunction(ED). A recent study in the same setting showed that prevalence of ED was high among diabetic men and co-existing hypertension was identified as an independent risk factor. There was a postulation about an association between ED and non-dipping nocturnal blood pressure pattern. So ambulatory blood pressure measurements (ABPM) was obtained for participants to test this prediction. Data was analysed using SPSS 25 Version. Results Among 29 participants who underwent ABPM, 21 showed non-dipping pattern of nocturnal systolic blood pressure (72.4%; CI 54.3–86.3). Mean SBP of participants was 125.55 +_14.1 and Mean DBP was 81.5 + _12.82. There was no statistical difference observed in mean SBP and DBP between patients with dipping nocturnal SBP and non-dipping pattern (P > 0.05). Variability of SBP was high among the participants (Mean SD-11.96 +/_2.74) and DBP also showed relatively high variability (SD-9.28 +/_2.9). Mean dipping percentage of the SBP during sleep was 5.54 +/_6.66. A significant difference in heart rate (HR) between patients with non-dipping and dipping pattern was noted (P-0.034).

Abstract
There is a substantial increase in the total geriatric population worldwide. This change in demography calls for a greater, deeper, and thorough understanding of elderly and age-related issues. Even though sexuality is a basic and vital driving force, human sexuality, especially elderly sexuality, is frequently misunderstood. Many myths and misconceptions regarding elderly sexuality exist which need attention. Contrary to the popular belief, studies reveal that sexual life continues to be an important aspect in later life and is often viewed by elderly as an expression of love, passion, affection, admiration, and loyalty. Various factors play a role in elderly sexuality including that of bio-psycho-social factors, changes in the body, presence of comorbid conditions along with sexual disorders. Sexual disorders, if present, should be treated and addressed adequately.

Abstract
Background: The problems in sexual functioning among patients with post-traumatic stress disorder (PTSD) are often overlooked, although scientific research confirms high rates of sexual dysfunctions (SD) particularly among veterans with PTSD. The main objective of this study was to systematically identify predictors of SD among veterans with PTSD. Methods: Three hundred veterans with PTSD were included in the cross-sectional study. The subjects were assessed by the Mini-International Neuropsychiatric Interview (MINI) and self-report questionnaires: PCL-5, i.e., PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) with Criterion A, International Index of Erectile Function (IIEF), Premature Ejaculation Diagnostic Tool (PEDT), and Relationship Assessment Scale (RAS). Several hierarchical multiple regressions were performed to test for the best prediction models for outcome variables of different types of SD. Results: 65% of participants received a provisional diagnosis of SD. All tested prediction models showed a good model fit. The significant individual predictors were cluster D (Trauma-Related Negative Alterations in Cognition and Mood) symptoms (for all types of SD) and in a relationship status/relationship satisfaction (all, except for premature ejaculation (PE)). Conclusions: The most salient implication of this study is the importance of sexual health assessment in veterans with PTSD. Therapeutic interventions should be focused on D symptoms and intended to improve relationship functioning with the aim to lessen the rates of SD. Psychotropic treatment with fewer adverse sexual effects is of utmost importance if pharmacotherapy is applied. Appropriate prevention, screening, and treatment of medical conditions could improve sexual functioning in veterans with PTSD.

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
Background: A good quality sex life and interest in sex are positively associated with health in middle-aged and later life. For effective diagnosis of sexual health problems, an appropriate discussion about sexual health issues including a sexual history is advised. The sexual health care delivery and management during consultations by primary care physicians is relatively unexplored, especially for older patients. This paper aims to explore primary health care physicians’ (PCPs) attitudes to sexual health care and management of middle-aged and older patients in Trinidad and Tobago. Methods: In-depth, semi-structured interviews were conducted with 35 PCPs in Trinidad and Tobago. Topics examined included physician-patient relations, sexual health care management challenges, communication and sexual history taking practices, and training needs of PCPs. The framework analysis method was adopted for analysis. Results: Most doctors stated that they were not comfortable with conducting a sexual history with their older patients, and they rarely discussed or initiated talking about sexual health with them. Barriers included time constraints, inappropriate environmental conditions for privacy, inadequate professional referral services, insufficient medical training in sexual function in middle and old age, reluctant patient behavior, conflicting personal beliefs on sexuality, and socio-cultural factors. Conclusion: PCPs may be reluctant to raise sexual health-related issues with their older patients, and these older patients may not initiate this discussion because of discomfort and embarrassment. Consequently, physicians’ inability to effectively communicate with these patients could result in missed opportunities for interventions and patients’ concerns may remain unheard and their sexual problems untreated.

Abstract
Erectile dysfunction (ED) affects millions of men worldwide. Men with ED generally complain failure to attain or maintain an adequate erection during sexual activity. The prevalence of ED is strongly correlated with age, affecting about 40% of men at age 40 and nearly 70% at age 70. A variety of chronic diseases, including diabetes, ischemic heart disease, congestive heart failure, hypertension, depression, chronic renal failure, obstructive sleep apnea, prostate disease, gout, and sleep disorder, were reported to be associated with ED. In this study, data retrieved from a subset of the National Health Insurance Research Database of Taiwan were used for designing the clinical decision support system (CDSS) for predicting ED incidences in men. The positive cases were male patients aged 20-65 who were diagnosed with ED between January 2000 and December 2010 confirmed by at least three outpatient visits or at least one inpatient visit, while the negative cases were randomly selected from the database without a history of ED and were frequency (1:1), age, and index year matched with the ED patients. Data of a total of 2832 ED patients and 2832 non-ED patients, each consisting of 41 features including index age, 10 comorbidities, and 30 other comorbidity-related variables, were retrieved for designing the predictive models. Integrated genetic algorithm and support vector machine was adopted to design the CDSSs with two experiments of independent training and testing (ITT) conducted to verify their effectiveness. In the 1st ITT experiment, data extracted from January 2000 till December 2005 (61.51%, 1742 positive cases and 1742 negative cases) were used for training and validating and the data retrieved from January 2006 till December 2010 were used for testing (38.49%), whereas in the 2nd ITT experiment, data in the training set (77.78%) were extracted from January 2000 till Deceber 2007 and those in the testing set (22.22%) were retrieved afterward. Tenfold cross validation and three different objective functions were adopted for obtaining the optimal models with best predictive performance in the training phase. The testing results show that the CDSSs achieved a predictive performance with accuracy, sensitivity, specificity, g-mean, and area under ROC curve of 74.72%-76.65%, 72.33%-83.76%, 69.54%-77.10%, 0.7468-0.7632, and 0.766-0.817, respectively. In conclusion, the CDSSs designed based on cost-sensitive objective functions as well as salient comorbidity-related features achieve satisfactory predictive performance for predicting ED incidences.

Abstract
The primary aim of this study was to evaluate penile endothelial microvascular function in patients with primary arterial hypertension and age-matched normotensive subjects using laser speckle contrast imaging (LSCI). Additionally, we analyzed the acute penile microvascular effects induced by oral phosphodiesterase type 5 inhibitor (sildenafil; SIL) administration. Endothelium-dependent microvascular reactivity was evaluated in the penises and forearms of hypertensive patients (aged 58.8±6.6 years, n=34) and age-matched healthy volunteers (n=33) at rest and 60 min following oral SIL (100 mg) administration. LSCI was coupled with cutaneous acetylcholine (ACh) iontophoresis using increasing anodal currents. Basal penile cutaneous vascular conductance (CVC) values were not significantly different between control subjects and hypertensive individuals. Penile CVC values increased significantly after SIL administration in control (P<0.0001) and hypertensive (P<0.0001) subjects. Peak CVC values were not different between the two groups during penile ACh iontophoresis before SIL administration (P=0.2052). Peak CVC values were higher in control subjects than in hypertensive subjects after SIL administration (P=0.0427). Penile endothelium-dependent microvascular function is, to some extent, preserved in patients presenting with primary arterial hypertension under effective anti-hypertensive treatment. LSCI may be a valuable non-invasive tool for the evaluation of penile vascular responses to phosphodiesterase type 5 inhibitor.

Abstract
BACKGROUND Erectile dysfunction (ED) is the most common male sexual disorder that affects all age groups and has a close association with essential hypertension. AIM To characterize the relation of blood pressure and ED in detail. METHODS A cross-sectional population-based study of 45- to 70-year-old men without previously diagnosed hypertension, cardiovascular diseases, renal disease, or diabetes was conducted from 2005 to 2007 in southwestern Finland. A total of 665 men with at least one cardiovascular risk factor were studied. ED was defined by the five-item International Index of Erectile Function. OUTCOMES We found a U-shaped association between diastolic blood pressure (DBP) and prevalence of ED. RESULTS The average age of the study subjects was 56 ± 6 years and 52% had ED. After adjustment for age, cohabitation status, education, fasting plasma glucose level, waist circumference, and prevalence of depressive symptoms, the curve relating DBP to the prevalence of ED was U-shaped with a nadir of DBP 90 mm Hg. CLINICAL IMPLICATIONS Our findings emphasize the importance of blood pressure measurement in the physical examination of men with ED. STRENGTHS AND LIMITATIONS This was a cross-sectional study, which prevents the evaluation of causality between ED and hypertension. However, this community-based study population is well defined and the anthropologic measurements were made by trained medical staff. CONCLUSION We found a U-shaped correlation between ED and DBP, which confirms the link between ED and hypertension. Heikkilä A, Kaipia A, Venermo M, et al.

Abstract
This study was conducted in a tertiary medical center in Kuala Lumpur, Malaysia. A total of 200 erectile dysfunction (ED) patients with 499 cases who had received pharmacological treatments for their ED participated in this study. Types, causes and factors associated with drug-related problems (DRPs) in ED patients with multiple comorbidities were assessed. A total of 244 DRPs with an average of 1.2±2.1 DRPs per patient were identified. Drug interaction contributed the most to DRPs occurrence. There was a significant higher risk of DRPs in patients with benign prostatic hyperplasia, lower urinary tract infection and elderly and end-stage renal disease. Early identification of types of DRPs and factors associated may enhance their prevention and management.

Abstract
Hyperlipidemia is an important risk factor for atherosclerosis and is frequently seen in patients with erectile dysfunction (ED). This study was designed to evaluate whether the acute effect of native low-density lipoprotein (nLDL) on intracavernosal pressure (ICP) is reversible and related to plasma asymmetrical dimethylarginine (ADMA), endogenous inhibition of endothelial nitric oxide synthase (eNOS) levels and eNOS expression in cavernous tissues. Hyperlipidemia was induced by a single dose of intravenous 4 mg kg-1 nLDL. Experiments were performed 72 h (72H), 2 weeks (2W) and 8 weeks (8W) after nLDL injection. Endothelium-dependent relaxations, the ratio of ICP to mean arterial pressure (MAP; ICP/MAP), plasma ADMA levels and eNOS mRNA and protein levels were evaluated. The ICP/MAP ratio decreased in both the 2W and 8W groups. Endothelium-dependent relaxation responses to acetylcholine in the rat thoracic aorta were damaged in the 8W group. Plasma ADMA levels increased in the 8W group. mRNA expression of eNOS decreased in a time-dependent manner, whereas the protein expression increased. These results suggest that acute nLDL injection-induced impairments in erectile functions during an 8-week period are irreversible and might be related to an increase in ADMA levels and changes in the regulation of the eNOS/NO pathway.

Abstract
BACKGROUND Erectile dysfunction (ED) is common in older men with chronic kidney disease. Magnesium is essential for metabolism of nitric oxide which helps in penile erection. There is little information available about the influence of serum magnesium on ED. The aim of the study was to assess the influence of hypomagnesemia on ED in elderly chronic kidney disease patients. SUBJECTS AND METHODS A total of 372 patients aged 65-85 years, with an estimated glomerular filtration rate of 60-15 mL/min/1.73 m2, were divided into two groups according to serum magnesium levels: hypomagnesemia, n=180; and normomagnesemia, n=192. ED was assessed through the International Index of Erectile Function-5. Hypomagnesemia is defined as serum magnesium <1.8 mg/dL. RESULTS The prevalence of ED was higher among hypomagnesemic subjects compared to that among normomagnesemics (93.3% vs 70.8%, P<0.001). Severe ED (62.8% vs 43.8%, P=0.037), mild-to-moderate ED (12.2% vs 5.2%, P=0.016), abdominal obesity (37.2% vs 22.9%, P=0.003), metabolic syndrome (38.4% vs 19.2%, P=0.026), proteinuria (0.83±0.68 vs 0.69±0.48 mg/dL, P=0.023), and C-reactive protein (6.1±4.9 vs 4.1±3.6 mg/L, P<0.001) were high; high-density lipoprotein cholesterol (48.8±14.0 vs 52.6±13.5 mg/dL, P=0.009), and albumin (4.02±0.53 vs 4.18±0.38 g/dL, P=0.001) were low in the hypomagnesemia group. Serum magnesium ≤1.85 mg/dL was the best cutoff point for prediction of ED. Hypomagnesemia (relative risk [RR] 2.27), age ≥70 (RR 1.74), proteinuria (RR 1.80), smoking (RR 21.12), C-reactive protein (RR 1.34), abdominal obesity (RR 3.92), and hypertension (RR 2.14) were predictors of ED. CONCLUSION Our data support that ED is related to hypomagnesemia in elderly patients with moderately to severely reduced kidney function.

Abstract
Chronic inflammation may cause endothelial dysfunction and atherosclerosis, resulting in subsequent erectile dysfunction (ED). We examined the relationship between chronic osteomyelitis, which is a chronic inflammatory disease, and ED. A retrospective cohort study was conducted using data from the National Health Insurance Research Database. After excluding patients <40 years of age, 677 male patients newly diagnosed with chronic osteomyelitis (COM) from 1 January 2000 to 31 December 2011 were identified for the study. The non-osteomyelitis comparison cohort consisted of 2706 male participants. The incidence of ED was 2.66-fold higher in the COM cohort than in the non-osteomyelitis cohort (4.01 vs 1.51 per 10 000 person-years). After adjusting for age and comorbidities of coronary heart disease, hypertension, hyperlipidemia, depression, stroke, diabetes, peripheral vascular disease, chronic kidney disease, chronic obstructive pulmonary disease and asthma, the patients with COM had a 2.82-fold risk of ED (95% confidence interval=1.44-5.56). The incidence of ED increased with that of comorbidities in both cohorts. The highest hazard ratio was in patients between 40 and 59 years of age who had COM. Our data showed, for the first time, that COM is a possible risk factor for the development of ED.

Abstract
PURPOSE OF REVIEW Erectile dysfunction is a common sexual disorder affecting 40% of men in the United States. However, the pathophysiologic mechanism involved in the causation of erectile dysfunction is multifactorial and not well delineated. RECENT FINDINGS Several recent studies disclose that erectile dysfunction is the result of multiple interrelated comorbid conditions that include hypertension, coronary artery disease (CAD), heart failure, and diabetes mellitus among them. In addition to comorbid conditions, certain cardiovascular and antihypertensive drugs are also involved in the development of erectile dysfunction, with the most prominent being the thiazide type diuretics, the aldosterone receptor blockers, and the β-adrenergic receptor blockers. Also, knowledge by the patient of the drug and its action on erectile dysfunction may increase the incidence of erectile dysfunction (Hawthorn effect). Before treatment is initiated, patients should be screened for the presence of erectile dysfunction, because this condition is associated with hypertension, CAD, heart failure, diabetes mellitus, and their treatment and an appropriate treatment regimen should be selected. If that fails, the addition of phosphodiesterase 5 inhibitors to the treatment regimen is recommended. The only exception is a patient with CAD treated with organic nitrates, in which the coadministration of phosphodiesterase 5 inhibitors is strictly prohibited. SUMMARY Knowledge of the various comorbid conditions and their treatment associated with the development of erectile dysfunction will help the caring physician to treat his patients appropriately and safely. All these aspects will be discussed in this review.

Abstract
Diabetes can be described as a syndrome of multiple closely related conditions induced by a chronic state of hyperglycaemia resulting from defective insulin secretion, insulin action or both. Chronic complications associated with diabetes (including neuropathy, vascular disease, nephropathy and retinopathy) are common, and of these, erectile dysfunction (ED) deserves special attention. ED and its correlation with cardiovascular disease require careful evaluation and appropriate treatment. PDE5 inhibitors (PDE5is) are an important tool for the treatment of ED, with new drugs coming onto the market since the late 90s. This review offers an overview of PDE5is and their use in treating ED in diabetes. We underline the differences between different types of PDE5i, focusing on available doses, duration of action, T ½, side effects and selectivity profiles in relation to patients with diabetes. We also discuss the link between diabetes and ED in presence of various associated cofactors (obesity, hypertension and its pharmacological treatments, atherosclerosis, hyperhomocysteinaemia, neuropathy, nephropathy, hypogonadism and depression). Finally a number of past and ongoing clinical trials on the use of PDE5is in patients with diabetes are presented to offer an overview of the appropriate treatment of ED in this condition.

Abstract
Background: Published clinical practice guidelines have addressed antihypertensive therapy and sexual dysfunction (SD) in many different ways. Objective: In this systematic review, we evaluated guidelines that address antihypertensive drug-associated SD, guideline recommendations, and recent guideline trends. Methods: Thirty sets of guidelines for hypertension management in adults that had been published in the English language since 2000 were reviewed. The primary outcome measure was antihypertensive-associated SD potential, which was independently evaluated using specific questions by 2 authors in a nonblinded standardized manner. Results: Sexual dysfunctions associated with thiazide-class diuretics, β-blockers, and centrally acting sympathoplegics were addressed by half of the guidelines reviewed. There is no clarity on β-blockers and thiazide-class diuretics because one-third of the guidelines are vague about individual β-blockers and diuretics, and there is no statement on third-generation β-blockers and thiazide-like diuretics that can improve erectile function. The revised guidelines never use terms such as loss of libido, ejaculatory dysfunction, lack of orgasm, and priapism. Summary versions of guidelines are inadequate to reflect the key interpretation of the primary guidelines on SD associated with antihypertensives, even in the major guidelines that were updated recently. Therapeutic issues such as exploring SD in clinical history, assessing SD prior to and during treatment with antihypertensives, substituting the offending agents with alternatives that possess a better safety profile, intervening with phosphodiesterase-5 inhibitors, and avoiding the concomitant use of nitrovasodilators are superficially addressed by most guidelines, with the exception of 2013 European Society of Hypertension/European Society of Cardiology and Seventh Joint National Committee recommendations. Conclusion: Future guideline revisions, including both full and summary reports, should provide a balanced perspective on antihypertensive-related SD issues to improve the impact of hypertension treatment guidelines on patient care and quality of life.

Association Between Dosage Frequency and the Treatment Outcomes of Sildenafil in Young and Middle-aged Men With Erectile Dysfunction: A Chinese, Multicenter, Observational Study. Urology 2015; 86:62-7. [PMID: 26142584 DOI: 10.1016/j.urology.2015.03.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2015] [Revised: 03/09/2015] [Accepted: 03/13/2015] [Indexed: 11/17/2022]
Abstract
OBJECTIVE To evaluate the correlation between the dosage frequency of sildenafil and its treatment outcomes in men with erectile dysfunction (ED). METHODS Data were from a 4-week, multicenter, observational study of men (1699), between 18 and 60 years of age, with a clinical diagnosis of ED defined as the Sexual Health Inventory for Men (SHIM) score ≤21. The erectile function and quality of sexual life were evaluated at the baseline and the endpoint of sildenafil treatment (after 4 weeks) by using SHIM, Self-Esteem and Relationship Questionnaire, 36-Item Short Form Health Survey, Erection Hardness Score, and the global efficacy question. RESULTS Nine hundred thirty-five patients were enrolled in the ≤1 weekly, 573 in the 2-3 weekly, and 158 in the 4-7 weekly dosage frequency cohorts. After 4 weeks of treatment, a higher dosage frequency of sildenafil was associated with a better SHIM, Self-Esteem and Relationship Questionnaire, and 36-Item Short Form Health Survey score improvement (all P <.0001). Hyperlipidemia is a poor prognostic factor (odds ratio, 3.59; P = .04), whereas hypertension (odds ratio, 0.25; P <.01) and coronary heart disease (odds ratio, 0.56; P = .05) are sensitive to sildenafil treatment. CONCLUSION Higher dosage frequency of sildenafil is associated with a better improvement of sexual function and quality of life of men with ED, and the concomitant treatment of hyperlipidemia is recommended.

Abstract
Background An association between lichen simplex chronicus (LSC) and sexual dysfunction was explored. However, no data are available from investigations into the relationship between erectile dysfunction (ED) and LSC. Objectives This retrospective population-based cohort study aimed to clarify the risk of ED associated with LSC. Methods By using the Taiwan National Health Insurance Research dataset, we identified 5611 male patients who had been newly diagnosed with LSC from 2000 to 2004. The date of diagnosis was identified as the index date. LSC patients with incomplete demographic information or with a history of ED before the index date were excluded. In total, 22444 age-matched patients without LSC were randomly selected as the non-LSC group based on a 1:4 ratio. Subsequence occurrence of ED was measured until 2011. The association between LSC and the risk of developing ED was estimated using Cox proportional hazard regression model. Results After adjusting for age and comorbidities, patients with LSC had a 1.74-fold greater risk of developing ED compared with those without LSC (95% confidence interval=1.44–2.10). LSC patients with comorbidities including diabetes, hyperlipidemia, hypertension, cardiovascular disease, peripheral arterial disease, chronic obstructive pulmonary disease, chronic kidney disease, depression, and anxiety were at a higher risk of ED compared with the non-LSC patients without comorbidities. Conclusions LSC confers a greater risk in the development of ED. Physicians should be aware of the potential of ED occurrence in LSC patients.

Low-dose spironolactone reduces plasma fibulin-1 levels in patients with type 2 diabetes and resistant hypertension. J Hum Hypertens 2014; 29:28-32.

Abstract
Diabetic patients with hypertension are at particularly high risk of vascular damage and consequently cardiovascular and renal disease. Fibulin-1, an extracellular matrix glycoprotein, is increased in arterial tissue and plasma from individuals with type 2 diabetes. This study aimed to evaluate whether antihypertensive treatment with spironolactone changes plasma fibulin-1 levels. In a multicenter, double-blind, randomized, placebo-controlled study, 119 patients with type 2 diabetes and resistant hypertension were included. A dose of spironolactone 25 mg or matching placebo was added to previous treatment at randomization. Blood pressure (BP) and plasma fibulin-1 were measured at baseline and at 16 weeks follow-up. Overall, 112 patients completed the study. All measures of BP were reduced in the spironolactone group at follow-up. Plasma fibulin-1 was significantly reduced after spironolactone treatment (P=0.009), but increased after placebo (P=0.017). Baseline plasma fibulin-1 correlated with BP and estimated glomerular filtration rate. Increased levels of plasma fibulin-1 (P=0.004) were observed in diabetic participants reporting erectile dysfunction as compared with participants who did not. Treatment with low-dose spironolactone reduced plasma fibulin-1 levels in patients with type 2 diabetes and resistant hypertension. This supports the hypothesis that the antihypertensive effect of the mineralocorticoid receptor blocker in part may be due to regression of vascular remodeling.

Abstract
This retrospective population-based study aimed to investigate associations between erectile dysfunction (ED) and the irritable bowel syndrome (IBS) using a Taiwanese cohort. We identified 17 608 male patients who were newly diagnosed with IBS from 1997 to 2010. The date that the diagnosis of IBS had been made was the index date. IBS patients with a history of ED before the index date or with incomplete demographic information were excluded. 70 432 age-matched subjects without IBS were selected as comparison cohort. Both cohorts were followed until the end of 2010 or censored. Cox proportional hazard regression model was used to estimate the effects of IBS on ED risks. The incidence rate ratio of ED in the IBS cohort was 2.92 times higher than that in the non-IBS cohort (29.5 vs. 10.1 per 10 000 person-years), with an adjusted hazard ratio (aHR) of 2.58 (95% confidence interval [CI]: 2.24-2.98). The risk of ED increased with increasing age and number of comorbidities. Patients with depression were at a higher risk of ED (aHR: 1.97; 95% CI: 1.49-2.63) compared with the subjects without depression. IBS patients had a higher risk of developing ED compared with non-IBS subjects. Ageing and comorbidities including diabetes, cardiovascular disease, chronic kidney disease and depression were associated with the risk of ED.

Abstract
Judaism has a positive attitude to sexual relations within a marriage, and views such sexual relations as important not only for procreation but also as part of the framework of marriage. This is true for any age group, and sexuality is seen as an essential element of marriage for couples of advanced age. In this article, the authors present the views of Jewish law and thought regarding sexuality among older couples. The authors illustrate this using 3 case studies of couples who sought guidance in the area of sexuality. In addition, this area of counseling benefits greatly from an ongoing relationship and dialogue between expert rabbis in the field and therapists treating older Orthodox Jewish patients for sexual dysfunction. The triad relationship of couple, therapist, and rabbi enhances the ability to treat and assist such couples to seek treatment and overcome their difficulties.

Abstract
OBJECTIVE To investigate the association of erectile dysfunction (ED) with commonly used medications including antihypertensive treatment (AHT), psychoactive medication and pain and anti-inflammatory medication. SUBJECTS AND METHODS The Boston Area Community Health (BACH) survey used a multistage stratified design to recruit a random sample of 2301 men aged 30-79 years. ED was assessed using the five-item International Index of Erectile Function (IIEF-5). Prescription medications, captured using a combination of drug inventory and self-report with a prompt by indication, included in this analysis comprised AHT, psychoactive medication, and pain and anti-inflammatory medication. Logistic regression was used to estimate the odds ratios (ORs) of the association of medication use with ED and to adjust for potential confounders including age, comorbid conditions and sociodemographic and lifestyle factors. RESULTS Multivariable analyses showed benzodiazepines (adjusted OR = 2.34, 95% confidence interval [CI]: 1.03, 5.31) and tricyclic antidepressants (adjusted OR = 3.35, 95% CI: 1.09, 10.27) were associated with ED, while no association was observed for serotonin reuptake inhibitors/serotonin-norepinephrine reuptake inhibitors and atypical antipsychotics. The use of AHT, whether in monotherapy or in conjunction with other AHTs, and pain or anti-inflammatory medications were not associated with ED after accounting for confounding factors. CONCLUSIONS Results of the BACH survey suggest adverse effects of some psychoactive medications (benzodiazepines and tricyclic antidepressants). No evidence of an association of AHT or pain and anti-inflammatory medication with ED was observed.
