Abstract
Effective representation of molecules is a crucial step in AI-driven drug design and drug discovery, especially for drug-drug interaction (DDIs) prediction. Previous work usually models the drug information from the drug-related knowledge graph or the single drug molecules, but the interaction information between molecular substructures of drug pair is seldom considered, thus often ignoring the influence of bond information on atom node representation, leading to insufficient drug representation. Moreover, key molecular substructures have significant contribution to the DDIs prediction results. Therefore, in this work, we propose a novel Graph learning framework of Mutual Interaction Attention mechanism (called GMIA) to predict DDIs by effectively representing the drug molecules. Specifically, we build the node-edge message communication encoder to aggregate atom node and the incoming edge information for atom node representation and design the mutual interaction attention decoder to capture the mutual interaction context between molecular graphs of drug pairs. GMIA can bridge the gap between two encoders for the single drug molecules by attention mechanism. We also design a co-attention matrix to analyze the significance of different-size substructures obtained from the encoder-decoder layer and provide interpretability. In comparison with other recent state-of-the-art methods, our GMIA achieves the best results in terms of area under the precision-recall-curve (AUPR), area under the ROC curve (AUC), and F1 score on two different scale datasets. The case study indicates that our GMIA can detect the key substructure for potential DDIs, demonstrating the enhanced performance and interpretation ability of GMIA.

[PMID: 27151768 PMCID: PMC5005302 DOI: 10.1016/j.esxm.2016.03.027] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2015] [Revised: 02/24/2016] [Accepted: 03/15/2016] [Indexed: 11/24/2022] Open
Abstract
INTRODUCTION Erectile dysfunction (ED) is prevalent in men with metabolic syndrome (MetS); therefore, it is important to characterize ED treatments in this population. AIMS To investigate the safety and effectiveness of vardenafil in men with ED and MetS in a clinical setting. METHODS REVITALISE is an international, prospective, single-arm, observational study in men with ED and MetS newly prescribed vardenafil. Vardenafil was prescribed at the discretion of the treating physician in line with the marketing authorization. Treatment effectiveness (International Index of Erectile Function [IIEF]) and health-related quality of life (Aging Males' Symptoms Scale) were assessed at treatment initiation, at an optional dose adjustment visit after approximately 4 weeks, and at the end of the observation period (approximately 12 weeks). MAIN OUTCOME MEASURES The primary outcome was an intraindividual improvement in erectile function (EF), defined as an increase of at least four points in the EF domain of the IIEF. Secondary outcomes included assessing normal EF (IIEF-EF score ≥ 26), mild ED (IIEF-EF score = 22-25), and health-related quality of life. Treatment-emergent adverse events were monitored. RESULTS In the intent-to-treat population (n = 1,832, mean age = 54.0 years, mean body mass index = 31.82 kg/m(2), Asian 36.8%, white 49.9%, 20.4% with severe ED, 75.6% with mild or moderate ED, 4.0% without ED), 82.4% reported an increase of at least four points in IIEF-EF score. Median IIEF-EF score increased from 15.0 (baseline) to 25.0 at 12 weeks (P < .0001). After treatment, 45.4% and 29.4% (intent-to-treat population) had normal EF and mild ED, respectively. Improvements in the sexual, psychological, and somatic subscales of the Aging Males' Symptoms Scale were found (P < .0001). Treatment-emergent adverse events were reported by 7.19% of patients; there were no serious adverse events related to vardenafil. CONCLUSION In a clinical setting, men with ED and MetS treated with vardenafil reported improvements in EF and health-related quality of life; and the safety profile of vardenafil was acceptable. REVITALISE demonstrates that vardenafil represents a good treatment option for men with ED and MetS.

Abstract
OBJECTIVE Penile prosthesis surgery is indicated based on undesirability, contraindication or ineffectiveness of non-surgical options for erectile dysfunction. This definitive treatment is often delayed after initial diagnosis. Our objective was to develop a prediction tool based on a patient's clinical history to determine likelihood of ultimately receiving a penile prosthesis. RESEARCH DESIGN AND METHODS This retrospective analysis used claims data from Commercial and Medicare supplemental databases. Inclusion criteria were 18 years of age with 1 year of continuous enrollment at the first diagnosis of erectile dysfunction. Patients' demographics, co-morbidities and erectile dysfunction therapy were derived based on enrollment, medical and prescription histories. MAIN OUTCOME MEASURES The Cox proportional hazards model with stepwise selection was used to identify and quantify (using relative risk) factors associated with a future penile prosthesis implant. Co-morbidities and therapies present prior to the index erectile dysfunction diagnosis were analyzed as fixed covariates. RESULTS Approximately 1% of the dataset's population (N = 310,303 Commercial, N = 74,315 Medicare, respectively) underwent penile prosthesis implantation during the study period (3928 patients in the overall population: 2405 patients [0.78%] in the Commercial and 1523 patients [2.05%] in the Medicare population). Factors with the greatest predictive strength of penile prosthesis implantation included prostate cancer diagnosis (relative risk: 3.93, 2.29; 95% CI, 3.57-4.34, 2.03-2.6), diabetes mellitus (2.31, 1.23; 2.12-2.52, 1.1-1.37) and previous treatment with first-line therapy (1.39, 1.33; 1.28-1.5, 1.2-1.47) (all P < 0.01). CONCLUSION The presence and extent of specific medical history factors at the time of erectile dysfunction diagnosis predict an individual's future likelihood of penile prosthesis. Calculating the likelihood of penile prosthesis implantation based on the weight of these factors may assist clinicians with the definition of a care plan and patient counseling. The precision of the model may be limited by factors beyond medical history information that possibly influence the decision to proceed to surgery.

Abstract
This study assessed the improvement in relationship quality, effectiveness and safety associated with vardenafil for the treatment of erectile dysfunction (ED). The study was conducted in 1433 centres across 21 countries and comprised a baseline patient visit and up to four follow-up visits during an observational period of 1 year. Relationship quality, happiness, satisfaction with vardenafil treatment, and safety and tolerability were assessed by physician interviews and patient and partner questionnaires. Overall, 7496 patients were enrolled in the study, of which 7430 were included in the safety analyses and 6470 in the effectiveness analyses. Relationship quality, assessed by a relationship questionnaire (partnerschaftsfragebogen [PFB]), was improved at last observation carried forward, compared with baseline, in both patients and partners and satisfaction with the effectiveness of vardenafil treatment was high. Vardenafil was well tolerated and adverse events were consistent with the known safety profile of phosphodiesterase type 5 inhibitors. These results confirm the well-established effectiveness and safety profiles of vardenafil. This study is the first to demonstrate improvements in relationship quality following vardenafil therapy, in both patients and partners, using the PFB questionnaire.

Abstract
In February 2011, the Korean Society for Sexual Medicine and Andrology (KSSMA) realized the necessity of developing a guideline on erectile dysfunction (ED) appropriate for the local context, and established a committee for the development of a guideline on ED. As many international guidelines based on objective evidence are available, the committee decided to adapt these guidelines for local needs instead of developing a new guideline. Considering the extensive research activities on ED in Korea, data with a high level of evidence among those reported by Korean researchers have been collected and included in the guideline development process. The latest KSSMA guideline on ED has been developed for urologists. The KSSMA hopes that this guideline will help urologists in clinical practice.

Abstract
Erectile dysfunction (ED) is an important worldwide health issue that has a significant negative impact on the quality of life and life satisfaction of both the affected individual and his partner. Here we review the prevalence of ED in Asia, associated factors that may influence sexual attitudes and sexual behaviours, and randomized clinical trials (RCTs) of phosphodiesterase-5 (PDE-5) inhibitors to evaluate the clinical efficacy and safety of PDE-5 inhibitors in Asian men. We searched for English-language articles in MEDLINE and PubMed from January 2000 to September 2010. Our results showed that the overall reported prevalence rate of ED in Asia ranged widely, from 2% to 88%. This finding indicates that ED is a common and major health problem in this region. However, sociocultural and economic factors in Asia prevent people from seeking and obtaining appropriate medical care. We found reports on five kinds of PDE-5 inhibitors for the management of ED: sildenafil, vardenafil, tadalafil, udenafil and mirodenafil. The results of RCTs showed that these five PDE-5 inhibitors are more effective than placebo in improving erectile function in Asian men with ED and that these drugs have similar efficacy and safety profiles.
