Assessment of Combination Therapies vs Monotherapy for Erectile Dysfunction: A Systematic Review and Meta-analysis.

Importance: Combining 2 first-line treatments for erectile dysfunction (ED) or initiating other modalities in addition to a first-line therapy may produce beneficial outcomes. Objective: To assess whether different ED combination therapies were associated with improved outcomes compared with first-line ED monotherapy in various subgroups of patients with ED. Data Sources: Studies were identified through a systematic search in MEDLINE, Cochrane Library, and Scopus from inception of these databases to October 10, 2020. Study Selection: Randomized clinical trials or prospective interventional studies of the outcomes of combination therapy vs recommended monotherapy in men with ED were identified. Only comparative human studies, which evaluated the change from baseline of self-reported erectile function using validated questionnaires, that were published in any language were included. Data Extraction and Synthesis: Data extraction and synthesis were performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Main Outcomes and Measures: A meta-analysis was conducted that included randomized clinical trials that compared outcomes of combination therapy with phosphodiesterase type 5 (PDE5) inhibitors plus another agent vs PDE5 inhibitor monotherapy. Separate analyses were performed for the mean International Index of Erectile Function (IIEF) score change from baseline and the number of adverse events (AEs) by different treatment modalities and subgroups of patients. Results: A total of 44 studies included 3853 men with a mean (SD) age of 55.8 (11.9) years. Combination therapy compared with monotherapy was associated with a mean IIEF score improvement of 1.76 points (95% CI, 1.27-2.24; I2 = 77%; 95% PI, -0.56 to 4.08). Adding daily tadalafil, low-intensity shockwave therapy, vacuum erectile device, folic acid, metformin hydrochloride, or angiotensin-converting enzyme inhibitors was associated with a significant IIEF score improvement, but each measure was based on only 1 study. Specifically, the weighted mean difference (WMD) in IIEF score was 1.70 (95% CI, 0.79-2.61) for the addition of daily tadalafil, 3.50 (95% CI, 0.22-6.78) for the addition of low-intensity shockwave therapy, 8.40 (95% CI, 4.90-11.90) for the addition of a vacuum erectile device, 3.46 (95% CI, 2.16-4.76) for the addition of folic acid, 4.90 (95% CI, 2.82-6.98) for the addition of metformin hydrochloride and 2.07 (95% CI, 1.37-2.77) for the addition of angiotensin-converting enzyme inhibitors. The addition of α-blockers to PDE5 inhibitors was not associated with improvement in IIEF score (WMD, 0.80; 95% CI, -0.06 to 1.65; I2 = 72%). Compared with monotherapy, combination therapy was associated with improved IIEF score in patients with hypogonadism (WMD, 1.61; 95% CI, 0.99-2.23; I2 = 0%), monotherapy-resistant ED (WMD, 4.38; 95% CI, 2.37-6.40; I2 = 52%), or prostatectomy-induced ED (WMD, 5.47; 95% CI, 3.11-7.83; I2 = 53%). The treatment-related AEs did not differ between combination therapy and monotherapy (odds ratio, 1.10; 95% CI, 0.66-1.85; I2 = 78%). Despite multiple subgroup and sensitivity analyses, the levels of heterogeneity remained high. Conclusions and Relevance: This study found that combination therapy of PDE5 inhibitors and antioxidants was associated with improved ED without increasing the AEs. Treatment with PDE5 inhibitors and daily tadalafil, shockwaves, or a vacuum device was associated with additional improvement, but this result was based on limited data. These findings suggest that combination therapy is safe, associated with improved outcomes, and should be considered as a first-line therapy for refractory, complex, or difficult-to-treat cases of ED.

Predictors of physicians' attitudes toward sharing information with patients and addressing psychosocial needs: a cross-sectional study in Greece.

Sharing information with patients and addressing their psychosocial needs are recognized as fundamental practices of patient-centered physicians. Our study explored predictors of physicians' patient-centered attitudes and yielded a better understanding of the relative influences of job satisfaction, employment status, specialty, previous communication skills training, and sociodemographic factors. Physicians who participated in 13 identical workshops offered throughout Greece were invited to complete a battery of anonymous questionnaires (demographics, job satisfaction scale, Patient-Practitioner Orientation Scale-Sharing subscale, and Physician Belief Scale). Prediction models were used to identify predictors of patient-centered attitudes. In total, 400 fully completed questionnaires were returned (response rate 79.8%). Job satisfaction, previous training in communication skills, younger age and lower socioeconomic status were predictors of positive attitudes toward sharing information with patients. Job satisfaction, previous training in communication skills, and stronger religious beliefs were predictors of higher psychosocial orientation. Job satisfaction and training in communication skills should be ensured in the effort to develop and maintain patient-centered attitudes in physicians. Religious beliefs, age, and socioeconomic status should be taken into consideration in the effort to help physicians become aware of their biases.

Gender and age differences in the perception of bother and health care seeking for lower urinary tract symptoms: results from the hospitalised and outpatients' profile and expectations study.

BACKGROUND: Few comparisons have been made of health care seeking behaviour for lower urinary tract symptoms (LUTS) between men and women, as well as trends across age groups. OBJECTIVE: To investigate the bother from LUTS and effect on health care seeking in both men and women of different age groups and in comparison between the two genders. DESIGN, SETTING, AND PARTICIPANTS: A representative cross section of each of 13 clinics of a general academic hospital, with equal numbers of subjects recruited in each of six design cells that were defined by age (18-40, 41-60, 61-80 yr) and gender. INTERVENTION: A 2-h in-person interview, conducted by a trained psychologist/interviewer in a clinic office. MEASUREMENTS: Severity of LUTS was measured by the International Prostate Symptom Score (IPSS). Treatment seeking was measured by a single item. A bother question was modified to assess overall bother. Impact on quality of life (QoL) was measured by the IPSS QoL question. RESULTS AND LIMITATIONS: The final study sample comprised 415 patients. More women than men reported the presence of LUTS (85.5% vs 75.2%; p=0.01). LUTS were more bothersome in women (25.4% of women vs 17.6% of men with bother "some" or "a lot"; p=0.02). Severity of LUTS increased with age in both genders (men: p<0.001; women: p=0.03). Bother from LUTS increased as severity of symptoms increased in both genders (p<0.001) but was associated with age only in men (p<0.001). QoL showed similar results as bother. Although men and women had equal prevalence of treatment seeking (27.9% vs 23.7%; p=0.40), men, but not women, were more likely to seek treatment as age (p<0.01) and severity of LUTS (p<0.001) increased. In multivariate logistic regressions, only bother from LUTS was associated with treatment seeking in women, compared with bother, age, and the presence of voiding symptoms in men. CONCLUSIONS: In our hospital-based sample, differences in LUTS frequency, bother, and health care seeking profiles between men and women suggest a different perception and response to LUTS between the two genders.

A conceptual framework for the evolution of sexual medicine and a model for the development of alternative sexual health services: 10-year experience of the center for sexual and reproductive health.

INTRODUCTION: Sexual health services are limited and inadequate to reduce factors that hinder treatment and adequate care, despite the growing interest for public awareness and prevention strategies. AIM: The aim of this study was to present an integrative conceptual framework, which led to the development of a model of alternative sexual health services and the 10-year experience of the practice of the service. MAIN OUTCOME MEASURES: Multiple-level needs assessments. METHODS: The conceptual framework is composed of four distinct elements: (i) it adopts a social/ecological perspective; (ii) it assumes that results are optimal when multiple interventions are used; (iii) interventions are influenced by behavioral theories; and (iv) sexual health is conceptualized through the biopsychosocial model. Based on this model, a Sexual and Reproductive Health Center was developed, dedicated to research, education, and public awareness. RESULTS: Over 10 years of experience show that the present approach constitutes a process which: (i) facilitates our understanding of the needs at individual, community, and system level; and (ii) increases the individuals', community and systems' capacity to control sexual health. CONCLUSION: Alternative models for sexual and reproductive health services should be encouraged, in order for best practices to be explored and identified. In addition, future research in the effectiveness of such interventions shall be beneficial in order for evidence-based interventions to be designed.
