Aim:To evaluate the association of erectile dysfunction (ED) with work productivity loss, activity impairment and health-related quality of life (HRQoL) across Brazil, China, France, Germany, Italy, Spain, the UK and the US. Methods:This cross-sectional observational study used data from adult men (40-70 years old; N = 52 697) from the 2015 and 2016 National Health and Wellness Surveys. ED assessment was based on self-reported difficulty in achieving or maintaining an erection in the past 6 months. Impairment to work and non-work activities and HRQoL were assessed for each country and compared against the US. Multivariable models tested interactions between ED status and country for each outcome. Results:Overall ED prevalence was reported as 49.7%, with Italy reporting the highest rate (54.7%). Men with ED reported significantly higher absenteeism (7.1% vs 3.2%), presenteeism (22.5% vs 10.1%), overall work productivity impairment (24.8% vs 11.2%), activity impairment (28.6% vs 14.5%) and significantly lower Mental Component Summary scores (MCS; 46.7 vs 51.2), Physical Component Summary scores (PCS; 48.3 vs 53.0), and health state utilities (SF-6D: 0.693 vs 0.778; all, P < 0.001) than men with no ED. After adjusting for covariates, compared with the US, the association of ED status with overall work productivity impairment was greatest in the UK (26% higher; P < 0.05), and with MCS, PCS and SF-6D scores was greatest in China (−2.67, −1.58, and −0.043 points, respectively; all, P < 0.001). Greater ED severity was significantly associated with higher impairment to work and non-work activities and lower HRQoL, with China reporting the highest burden, compared with the US (most P < 0.05).Conclusion: ED poses a significant burden with respect to work productivity and HRQoL, with greater severity associated with worse outcomes. Better management and earlier detection may help reduce this burden, especially in countries reporting a strong association between ED and poor economic and health outcomes. | INTRODUC TI ONErectile dysfunction (ED) is defined as the persistent inability to achieve and/or maintain penile erection sufficient for performing sexual intercourse. 1 ED can be caused by endocrine (reduced serum testosterone levels), non-endocrine (arterial inflow disorders and abnormalities of venous outflow), neurogenic (affecting innervation and nervous function) and iatrogenic (relating to a medical or surgical treatment) factors. 2 An extrapolation of the Massachusetts Male Aging Study, whichreported an ED prevalence of 52% in men aged 40-70 years, suggested that global ED prevalence will increase from 152 million

Background: In Japan, intravitreal anti-vascular endothelial growth factor (anti-VEGF) dosing regimens for wet age-related macular degeneration (wAMD) include pro re nata, every 2 months, and treat-and-extend, resulting in different outcomes and patient burden. Although reflecting patient preferences in treatment decision-making is desirable, few studies have examined this in Japan. This study assessed the patients willingness to trade-off between different dosing regimens. Patients and Methods: Patients with wAMD were recruited from four Japanese university hospitals to complete a face-to-face cross-sectional survey. In a discrete choice experiment, patients were asked to choose their preferred option from two anti-VEGF treatment profiles shown side-by-side across a series of choice tasks. The profiles varied on four attributes: number of injections in 12 months, number of physician consultations in 12 months, chance of 1-year visual acuity (VA) improvement, and chance of 2-year VA maintenance. Preference weights were estimated using hierarchical Bayes' models. Results: Overall, 120 patients (30 treatment naïve and 90 anti-VEGF experienced) completed the survey. Patients were willing to accept an increase from three to approximately eight injections in 12 months to increase the chance of 1-year VA improvement from 25% to 40%. They would be willing to accept 11 injections in 12 months if the chance of 2-year VA maintenance increased from 80% to 96%. The most valued attributes were increasing the chance of 2-year VA maintenance and reducing the number of injections in 12 months, which were each about twice as important as decreasing physician consultations in 12 months and increasing the chance of 1-year VA improvement (p<0.001). Among the dosing regimens, patients most preferred treat-and-extend because of its higher chance of 2-year VA maintenance. Conclusion: Informing patients with wAMD about the likelihood of long-term VA maintenance when selecting treatment may increase the acceptance of an optimal treatment regimen and number of injections.

Purpose To understand and compare preferences for dosing- and toxicity-related attributes associated with selective cyclin-dependent 4/6 kinase inhibitors regimens among US oncologists and patients. Materials and Methods Oncologists and patients with mBC participated in an internet-based survey that included a discrete choice experiment (DCE) and a best–worst scaling (BWS) exercise. For the DCE, participants chose between two hypothetical treatment profiles, each with seven attributes: risk of dose reduction due to adverse events (AEs), risk of diarrhea, risk of abdominal pain, need for electrocardiogram (ECG) monitoring to assess heart function, risk of Grade 3/4 neutropenia, dosing regimen, and dosing schedule. The BWS exercise assessed the relative prioritization of a larger set of 16 attributes. Hierarchical Bayesian models were used to estimate preference weights for each attribute level. Results Oncologists (N=209) and patients (N=304) rated risks of diarrhea (25% each) and Grade 3/4 neutropenia (20% and 24%, respectively) as the most important attributes for treatment choice. The risks of diarrhea and Grade 3/4 neutropenia were 1.8 to 2.3 times (oncologists: 25% and 20%, respectively vs 11%) and 2.4 to 2.5 times (patients: 25% and 24%, respectively vs 10%) higher in relative importance than the risk of dose reduction due to AEs. Oncologists placed greater importance on the risk of dose reduction due to AEs and the need for ECG monitoring, whereas patients placed greater importance on the risk of Grade 3/4 neutropenia (all, p<0.05). The BWS exercise results were largely consistent with those from the DCE. Conclusion The risks of diarrhea and Grade 3/4 neutropenia were key drivers of both oncologist and patient preferences. Overall, the palbociclib + aromatase inhibitor (AI) profile was most preferred, due to its association with a lower risk of diarrhea and no ECG monitoring, compared with abemaciclib + AI and ribociclib + AI profiles, respectively.
