ABSTRACT
Background: Educational programs that enhance healthcare providers' competence in managing the care of patients with sexual dysfunction following prostate cancer treatments are needed to facilitate comprehensive sexual health treatments for patients and their partners. Aim: In this study we evaluated the impact of a real-world online sexual health educational intervention called the True North Sexual Health and Rehabilitation eTraining Program. This program is designed to increase healthcare providers' knowledge and self-efficacy in providing sexual healthcare to prostate cancer patients and their partners. Methods: Healthcare providers were invited to join a 12-week virtual training program. Participants completed precourse surveys (n = 89), retrospective prepost surveys (n = 58), and a 3-month follow-up survey (subset n = 18) to assess retention of relevant outcomes. Additionally, a course satisfaction survey was administered to participants (n = 57) at the end of the course. Outcomes: The main outcomes focused on participants' perceived knowledge and self-efficacy in conducting assessments and providing interventions for various relevant physical, functional, psychological, and relational domains of sexual dysfunction in prostate cancer patients and their partners. Results: According to the retrospective analysis of post-then-pre-survey results, graduates perceived that their knowledge of and self-efficacy in providing sexual health counseling improved after completing the course. The 3-month follow-up survey indicated that the course graduate self-efficacy remained high 3 months after the course. Furthermore, the satisfaction survey indicated that a vast majority (98.2%) of participants were satisfied with the educational intervention. Clinical Implications: This real-world sexual health educational intervention can increase self-efficacy and knowledge in healthcare providers who are supporting prostate cancer patients dealing with sexual dysfunction. Strengths and Limitations: The use of a retrospective post-then-pre-survey helped to mitigate response shift bias while minimizing data gaps. However, it is important to note that this investigation was not a traditional research study and lacked a control group, thus limiting causal attributions. Conclusion: The True North Sexual Health and Rehabilitation eTraining program acts as an accessible and effective resource for healthcare providers seeking specialized training in providing sexual healthcare for prostate cancer patients and their partners.
ABSTRACT
Solvent exchange is a crucial step in ensuring the complete activation of metal-organic frameworks (MOFs); however, the conditions for solvent exchange vary among MOFs, even within the isostructural variants. This study examines the factors contributing to solvent exchange by investigating the isostructural M2(dobdc) (MâMg, Co, Zn) series. Common solvents N,N-dimethylformamide (DMF), ethanol (EtOH), and methanol (MeOH) are employed to assess the solvent exchange at coordinatively unsaturated sites (CUS) of M2(dobdc). By monitoring both solvents released from the MOF during solvent exchange and the coordination environment of metals within the MOF, a picture is constructed of exchange rates during early stages of solvent exchange as well as expulsion of the last traces of bound solvents. This differentiation is achieved by a combination of bulk monitoring of solvent phase composition and microscopic application of Raman spectroscopy on the single-crystal level. The kinetics of solvent replacement is revealed to have a substantial contribution from cooperativity; this phenomenon is observed in both the forward and reverse directions. Thermogravimetric analysis coupled with IR spectroscopy and density functional theory (DFT) calculations are employed to elucidate the relationship between solvent exchange rates and solvent binding energy. The solvent exchange rates are determined by the kinetic barriers of solvent exchange that do not follow the order of the solvent binding affinity. This work contributes to understanding the solvent exchange of MOFs by examining the interplay among the binding strength, exchange kinetics, and cooperativity. It further provides valuable insights for scrutinizing MOF activation protocols.
ABSTRACT
Bulk composition of kidney stones, often analyzed with infrared spectroscopy, plays an essential role in determining the course of treatment for kidney stone disease. Though bulk analysis of kidney stones can hint at the general causes of stone formation, it is necessary to understand kidney stone microstructure to further advance potential treatments that rely on in vivo dissolution of stones rather than surgery. The utility of Raman microscopy is demonstrated for the purpose of studying kidney stone microstructure with chemical maps at ≤ 1 µm scales collected for calcium oxalate, calcium phosphate, uric acid, and struvite stones. Observed microstructures are discussed with respect to kidney stone growth and dissolution with emphasis placed on < 5 µm features that would be difficult to identify using alternative techniques including micro computed tomography. These features include thin concentric rings of calcium oxalate monohydrate within uric acid stones and increased frequency of calcium oxalate crystals within regions of elongated crystal growth in a brushite stone. We relate these observations to potential concerns of clinical significance including dissolution of uric acid by raising urine pH and the higher rates of brushite stone recurrence compared to other non-infectious kidney stones.

Artificial phantoms used in photothermal near-infrared laser lithotripsy research generally fail to mimic both the chemical and the physical properties of human stones. Though high-energy, 1 J pulses are capable of fracturing hard human stones into several large fragments along natural boundaries, similar behavior has not been observed in commonly used gypsum plasters like BegoStone. We developed a new brushite-based plaster formulation composed of ≈90% brushite that undergoes rapid fracture in the manner of human stones under fragmentation pulse regimes. Single-pulse (1 J) ablation crater volumes for phantoms were not significantly different from those of pure brushite stones. Control over crater volumes was demonstrated by varying phosphorous acid concentration in the plaster formulation. Fragmentation of cylindrical brushite phantoms was filmed using a high-speed camera which demonstrated rapid fragmentation in < 100 µs during the bubble expansion phase of a short pulse from a high-powered Ho:YAG laser (Lumenis Pulse 120 H). The rapid nature of observed fracture suggests increasing laser pulse energy by increasing laser pulse duration will not improve fragmentation performance of laser lithotripters. Brushite plaster phantoms are a superior alternative to gypsum plasters for laser lithotripsy research due to their better mimicry of stone composition, controllable single-pulse crater volumes, and fragmentation behavior.

PURPOSE: Screening and discussion about sexual health concerns within cancer care are frequently impeded by lack of access to sexual health resources and lack of fluency with sexual health topics. To address this, a multi-disciplinary sexual health program was developed and piloted in a Canadian tertiary cancer center. The aim of this study was to assess referring health care providers' perspectives on the newly implemented oncology sexual health program. METHODS: A brief online survey was administered system-wide to cancer care providers to query their perceptions of the pilot multidisciplinary sexual health program, the Oncology and Sexuality, Intimacy and Survivorship (OASIS) program. RESULTS: According to survey results, the OASIS program was perceived by health care providers as valuable, helpful for patients, and important for addressing gaps in clinical care. Additional comments indicated an ongoing need for increased access to information about the program and referral procedures. CONCLUSION: Survey results highlight the need for consistent program dissemination efforts to equip health care providers with accessible patient education materials and easily implemented referral procedures. Importantly, providers indicated that they were more likely to raise the topic of sexuality with patients because they had somewhere to refer patients who had sexual concerns. Overall, findings inform efforts to implement sexual health programming within cancer care institutions.

PURPOSE: Untreated cancer-related sexual health concerns cause significant distress for cancer survivors. To appropriately address the complex sexual health needs of cancer patients, we piloted a specialized, multidisciplinary oncology sexual health clinic within a tertiary cancer center. A quality assurance evaluation was conducted. METHODS: During once monthly half-day clinics, a multidisciplinary team of psychologists, advanced practice nurses, and radiation and gynecological oncologists offered specialist integrated care to oncology patients. Patients completed assessment questionnaires prior to each clinic appointment and a follow-up telephone interview approximately 4 months after their initial appointment. RESULTS: Over the 2-year pilot, 224 patients were referred to the cancer center's broader sexual health program; 100 patients were triaged to the clinic. A total of 79 new and 58 follow-up appointments were offered. Average wait time for an initial visit was 97 days. Patients' most frequent concerns included vulvovaginal atrophy, dyspareunia, reduced sexual desire, and erectile dysfunction. Self-reported sexual distress was well above the clinical cutoff at baseline (N = 77, M = 29.78, SD = 12.74). A significant reduction in sexual distress was observed at follow-up (N = 67, M = 21.90, SD = 11.34, t(66) = 7.41, p < 0.001). CONCLUSIONS: Referral rates indicate a high demand for specialized sexual health services within cancer care. Ongoing specialist care is needed to appropriately address the multifaceted sexual concerns of cancer survivors and to adequately manage high distress and symptom comorbidity. IMPLICATIONS FOR CANCER SURVIVORS: Results inform a more comprehensive characterization of the presenting concerns of cancer survivors seeking multidisciplinary sexual health care.

Cancer-related sexual dysfunction is documented as one of the most distressing and long-lasting survivorship concerns of cancer patients. Canadian cancer patients routinely report sexuality concerns and difficulty getting help. In response to this gap in care, clinical practice guidelines were recently published in the Journal of Clinical Oncology. A sweeping trend is the creation of specialized clinics for patients' sexual health concerns. However, this much-needed attempt to address this service gap can be difficult to sustain without addressing the cancer care system from a broader perspective. Herein, we describe the implementation of a tiered systemic model of cancer-related sexual health programming in a tertiary cancer center. This program follows the Permission, Limited Information, Specific Suggestions, Intensive Therapy (PLISSIT) model, used previously for guiding individual practitioners. Visually, the model resembles a pyramid. The top 2 levels, corresponding to Intensive Therapy and Specific Suggestions, are comprised of group-based interventions for common cancer-related sexual concerns and a multi-disciplinary clinic for patients with complex concerns. The bottom 2 levels, corresponding to Permission and Limited Information, consist of patient education and provider education and consultation services. We describe lessons learned during the development and implementation of this program, including the necessity for group-based services to prevent inundation of referrals to the specialized clinic, and the observation that creating specialized resources also increased the likelihood that providers would inquire about patients' sexual concerns. Such lessons suggest that successful sexual health programming requires services from a systemic approach to increase sustainability.

IMPORTANCE: Treatment options for platinum-refractory metastatic urothelial cancer (mUC) are limited, and outcomes remain poor. Nab-paclitaxel is an albumin-bound formulation of paclitaxel showing promising activity and tolerability in a prior single-arm trial. OBJECTIVES: To evaluate the efficacy and safety of nab-paclitaxel vs paclitaxel in platinum-refractory mUC. DESIGN, SETTING, AND PARTICIPANTS: In this investigator-initiated, open-label, phase 2 randomized clinical trial conducted across Canada and Australia from January 2014 to April 2017, eligible patients had histologically confirmed, radiologically evident mUC of the urinary tract. Mixed histologic findings, except small cell, were permitted provided UC was the predominant histologic finding. All patients had received platinum-based chemotherapy either in the metastatic setting or were within 12 months of perioperative chemotherapy. Patients with prior taxane chemotherapy were not included. Patients had an Eastern Cooperative Oncology Group Performance Status (ECOG PS) 0 to 2 and adequate organ function. INTERVENTIONS: Patients were randomized to nab-paclitaxel, 260 mg/m2, or paclitaxel, 175 mg/m2, every 3 weeks. MAIN OUTCOMES AND MEASURES: The primary end point was progression-free survival (PFS). RESULTS: Among 199 patients, median age was 67 (range, 24-88) years; 144 (72%) were men; 167 (84%) were ECOG PS 0-1; 59 (30%) had liver metastases; and 110 (55%) were within 6 months of prior platinum-based chemotherapy. At a median follow-up of 16.4 months, there was no significant difference between nab-paclitaxel vs paclitaxel for median PFS (3.4 months vs 3.0 months; hazard ratio [HR], 0.92; 90% CI, 0.68-1.23; 1-sided P = .31). Median overall survival was 7.5 months for nab-paclitaxel vs 8.8 months for paclitaxel (HR, 0.95; 90% CI, 0.70-1.30; 1-sided P = .40); and objective response rate (ORR) was 22% for nab-paclitaxel vs 25% for paclitaxel (P = .97). Grade 3/4 adverse events were more frequent with nab-paclitaxel (64/97 [66%]) compared with paclitaxel (45/97 [46%]), P = .009; but peripheral sensory neuropathy was similar (all grades, 72/97 [74%] vs 64/97 [66%]; grade 3/4, 7/97 [7%] vs 3/97 [3%]; P = .27). There were no apparent differences in scores for health-related quality of life. CONCLUSIONS AND RELEVANCE: In this open-label, phase 2 randomized clinical trial of patients with platinum-refractory mUC, nab-paclitaxel had similar efficacy to paclitaxel; but worse toxic effects. The ORR with either taxane, however, was higher than previously reported and similar to those reported for the immune checkpoint inhibitors, suggesting that the taxanes remain a reasonable option in this setting. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02033993.

Androgen deprivation therapy (ADT), a common treatment for prostate cancer, is associated with physical, psychological, and sexual side effects that reduce patients' quality of life. The authors designed an educational program to prepare patients for managing these side effects. This paper describes an implementation model for national dissemination of the program, testing its feasibility and acceptability at the institutional and patient level. Postprogram changes in patients' self-efficacy to manage side effects and side effect bother are also explored. Patients on or anticipating ADT enrolled in the educational program. Pre and post intervention questionnaires measured patient satisfaction with the program, side effect bother, and self-efficacy to manage ADT side effects. The ADT Educational Program was deemed feasible and acceptable. Five of six targeted sites successfully launched the program with sufficient patient enrolment. Patient attendees were highly satisfied. Self-efficacy, bother, and use of management strategies were interrelated. Lower bother was associated with increased self-efficacy and more use of management strategies, and increased bother was associated with lower self-efficacy and less use of management strategies. Based on pre-post scores, improvements in patients' self-efficacy to manage ADT side effects were also observed. Results demonstrate that this brief educational program is feasible and acceptable to patients and cancer care institutions. The program appears to promote self-efficacy and the uptake of ADT management strategies for ADT side effects. The results of this study support the program implementation and suggest that improvements in self-efficacy after program participation may help patients adapt to ADT side effects.

PURPOSE: Sexual difficulties and vulvovaginal changes are common for women undergoing, and following, cancer treatments. These changes have significant impacts on quality of life and significant relationships. The current study aimed to (1) evaluate women's interest and attendance in a group-based educational workshop to address changes in vulvovaginal health and sexuality after cancer, and (2) describe participant characteristics and presenting concerns. METHODS: Two hundred eighteen women with a history of cancer expressed interest in receiving information about the workshop and completed phone screening. Interested women (n = 156) completed an online questionnaire package examining vulvovaginal health and sexual function prior to attending the workshop. RESULTS: Approximately 75% of the women who completed screening attended the workshop. Clinically significant sexual distress was reported by 91% of participants, and 97% of sexually active participants exceeded the threshold for sexual dysfunction (per FSFI). Women within 1-2 years of diagnosis tended to report less sexual distress, less severe vulvovaginal symptoms, and less impact from these symptoms compared to women farther out from diagnosis. While the majority of women reported vaginal dryness and pain during intercourse, only a minority reported engaging in health promotion strategies sufficient to expect symptom improvement. CONCLUSIONS: The current study suggests that group-based educational workshops for vulvovaginal and sexual concerns are utilized by patients and should be offered to women well into disease survivorship. Workshops targeting vulvovaginal symptoms and sexual concerns may be a cost-effective method of reducing sexual distress and improving patients' sexual function and quality of life.

PURPOSE: With the goal of improving the quality of sexual health care provision at our tertiary cancer centre, we developed, implemented, and assessed a multidisciplinary sexuality in an oncology program, to identify patient needs and apply interventions that could be effective in a broader oncology care context. METHODS: The establishment of our institution's first oncology-focused sexual health program is described within a quality improvement framework. A complementary retrospective chart review was performed to evaluate clinicodemographic data, including responses to validated sexual health questionnaires, from a 2-year clinical pilot. RESULTS: A sexual health program was introduced for cancer patients identified by health care providers or self-referred, receiving 130 referrals and conducting 64 consultation and 75 follow-up visits within a 2-year pilot period. Patients attending the program were 75% female, of mean age 52 years, and had most often breast (33%) or hematologic (30%) malignancies. Most (84%) had completed curative-intent treatment, with no evidence of disease, with 34% on ongoing endocrine therapy. The most frequent reasons for referral were sexual pain (38%), decreased libido (35%), and vaginal dryness (35% of females). All female patients demonstrated sexual dysfunction on the Female Sexual Function Index, and 80% of male patients demonstrated moderate to severe erectile dysfunction on the Sexual Health Inventory for Men. Patients waited a median of 63 days (SD 107, range 3-516) from referral to consultation, suggesting that demand for multidisciplinary sexual health care overwhelmed existing resources. CONCLUSIONS: We have demonstrated unmet sexual health needs across a diverse oncology patient population and have presented a framework for addressing these issues, highlighting the challenges encountered and proposing improvements. Insights emerging from a quality improvement perspective included the role of group-based sexual health support to improve accessibility and the need for staff education to encourage proactive intervention before referral for specialized care is needed.

BACKGROUND: Androgen deprivation therapy (ADT) for prostate cancer has numerous side effects. Clinical guidelines for side effect management exist; however, these are not always integrated into routine practice. What remains undocumented and therefore the objective of this study, is to describe patients' willingness to employ established strategies. PATIENTS AND METHODS: Study participants were 91 men who had attended an educational program (ie, attend a class plus read a book), designed to prepare patients for managing ADT side effects. Three months later, patients completed the ADT Management Strategies Inventory, to determine use of strategies. Descriptive analyses were conducted. RESULTS: At the time of class attendance, the average ADT duration was 133 days. Patient preferences for a variety of strategies for each side effect are presented. Highlights include: a high degree (> 65%) of patients using or willing to use exercise to manage medical risks and physical side effects. Forty percent of patients continued to engage in non-penetrative sexual activities, despite reduced sexual desire and erectile dysfunction. CONCLUSIONS: When educated about options, patients are willing to use a wide array of ADT management strategies. Consequently, health care providers should ensure that patients know about side effects and how to manage them. Exercise appears to be the single best strategy to encourage, because it is helpful in managing many side effects (eg, weight gain, muscle weakening, fatigue) and reducing medical risks of ADT (eg, cardiovascular disease, type II diabetes, and osteoporosis). A general trend was patient's preference for behavioral and lifestyle strategies over pharmacologic interventions.

PURPOSE: Communication and assessment of sexual health within cancer care is poor despite high rates of sexual dysfunction in cancer survivors. Screening for distress programs have been implemented, as a standardized part of cancer care across Canada, with the aim of increasing identification and improving access to support. Alberta Health Services uses a general distress screening form, containing the Canadian Problem Checklist, which includes a list of possible problems, one of which is "intimacy/sexuality." Theoretically, the discreet nature of the screening for distress form may reduce patient discomfort in disclosing sexual concerns verbally, and therefore help health care providers identify patients requiring intervention. This study aims to determine the adequacy of this distress screening tool in identifying gynecological cancer patients who have an intimacy/sexuality concern. METHODS: A chart review was conducted on all follow-up visits in a gyne-oncology clinic over 1 year. Each patient's chart was reviewed to determine the prevalence of the distress screening form completion, prevalence of the "intimacy/sexuality" item being checked, and documentation of actions taken to address any reported intimacy/sexuality problems. RESULTS: Seven hundred thirty patient visits were recorded during this period with completed distress screening forms found on 79.0% (n = 577) of charts. Only 6% of the patients indicated an intimacy/sexuality concern on this form. Of those, only one third had documentation that their problem was addressed. CONCLUSIONS: These results call into question the utility of the intimacy/sexuality item on the Canadian Problem Checklist to identify gynecological cancer patients who have sexual concerns. Furthermore, even among those patients who indicated concerns, there is evidence that their problems are rarely addressed. Providers need to directly inquire with patients about their sexual health.

The repercussions of cancer diagnosis and treatment profoundly impact the sexual wellbeing of women prior to, during, and following cancer treatment. Sexual health concerns are often under-addressed within clinical and research settings, and information tends to be limited to women with breast or gynecological cancers. In this narrative literature review, the authors critically evaluate research published between 1990 and 2016, pertaining to sexual health concerns of women diagnosed with cancer, of any type or stage, and to the psychosocial and biomedical interventions that currently exist for the treatment of sexual health-related side-effects (e.g. vaginal dryness, dyspareunia and vulvo-vaginal atrophy). The findings of 109 published articles are discussed and summarised according to four central themes: how cancer affects female sexual wellbeing; physical impacts of cancer diagnosis and treatment; emotional impacts of cancer diagnosis and treatment; and interventions for sexual dysfunction. Suggestions to enhance research and clinical practice in relation to the sexual health concerns of women following cancer treatments are also presented. Concerns pertaining to women's sexual health are diverse, multiple, and pervade all types and stages of cancer. Several evidence-based psychosocial and biomedical interventions exist to help women manage physical and psychosocial ramifications of cancer diagnosis and treatment.

OBJECTIVE: Prostate cancer (PCa) treatments often leave men with erectile dysfunction (ED). Even when ED treatments are effective in restoring men's ability to have an erection sufficient for intercourse, couples continue to struggle sexually. Effective treatments to help couples recover sexually are needed. METHOD: PCa patients and partners (N = 59 couples) attending a one-time couples' intimacy workshop, participated in an evaluation. The workshop, offered eight times over a 2-year period, emphasized a couples-based approach to treatment that enhances direct communication about sexuality and implementation of sexual recovery strategies that are consistent with the couple's values. Couples completed pre and post questionnaires (at baseline and 2 months later) assessing the primary outcome of relationship adjustment (Revised Dyadic Adjustment Scale) and secondary outcome of sexual function (Sexual Function Questionnaire). T-tests were employed to examine pre-post changes in scores. A small qualitative sub-study was conducted on the use of a Commitment to Change goal-setting exercise, completed during the workshop. RESULTS: Results provide insight into the specific nature of improvements. Patients and partners showed improvements in relationship satisfaction. Improvements with small-to-medium effect sizes were observed for patients and partners sexual function; however, after adjusting for multiple comparisons, these changes were no longer statistically significant. The specific goals set by couples, and their achievement status, are presented. CONCLUSIONS: The workshop offers a comprehensive, one-session intervention to help couples implement a treatment plan to promote sexual recovery after PCa treatment. Given the observed improvements, progression to a randomized control trial is warranted. Copyright © 2016 John Wiley & Sons, Ltd.

OBJECTIVES: To determine the impact of specific reporting tasks on the performance of radiologists when reading chest radiographs. METHODS: Ten experienced radiologists read a set of 40 postero-anterior (PA) chest radiographs: 21 nodule free and 19 with a proven solitary nodule. There were two reporting conditions: an unframed task (UFT) to report any abnormality and a framed task (FT) reporting only lung nodule/s. Jackknife free-response operating characteristic (JAFROC) figure of merit (FOM), specificity, location sensitivity and number of true positive (TP), false positive (FP), true negative (TN) and false negative (FN) decisions were used for analysis. RESULTS: JAFROC FOM for tasks showed a significant reduction in performance for framed tasks (P = 0.006) and an associated decrease in specificity (P = 0.011) but no alteration to the location sensitivity score. There was a significant increase in number of FP decisions made during framed versus unframed tasks for nodule-containing (P = 0.005) and nodule-free (P = 0.011) chest radiographs. No significant differences in TP were recorded. CONCLUSIONS: Radiologists report more FP decisions when given specific reporting instructions to search for nodules on chest radiographs. The relevance of clinical history supplied to radiologists is called into question and may induce a negative effect. KEY POINTS: ⢠Framed reporting tasks increases false positive rates when searching for pulmonary nodules ⢠False positive results were observed in both nodule-containing and nodule-free cases ⢠Radiologist's decision-making may be influenced by clinical history in thoracic imaging.

(241)Am has been deposited using a novel technique that employs a commercial inductively coupled plasma mass spectrometer. This work presents results of high-resolution alpha spectrometry on the (241)Am samples using a small area passivated implanted planar silicon detector. We have also investigated the mass-based separation capability by developing a (238)Pu sample, present as a minor constituent in a (244)Pu standard, and performed subsequent radiometric counting. With this new sample development method, the (241)Am samples achieved the intrinsic energy resolution of the detector used for these measurements. There was no detectable trace of any other isotopes contained in the (238)Pu implant demonstrating the mass-based separation (or enhancement) attainable with this technique.
ABSTRACT
The clinical benefits of androgen-deprivation therapy (ADT) for men with prostate cancer (PC) have been well documented and include living free from the symptoms of metastases for longer periods and improved quality of life. However, ADT comes with a host of its own serious side effects. There is considerable evidence of the adverse cardiovascular, metabolic, and musculoskeletal effects of ADT. Far less has been written about the psychological effects of ADT. This review highlights several adverse psychological effects of ADT. The authors provide evidence for the effect of ADT on men's sexual function, their partner, and their sexual relationship. Evidence of increased emotional lability and depressed mood in men who receive ADT is also presented, and the risk of depression in the patient's partner is discussed. The evidence for adverse cognitive effects with ADT is still emerging but suggests that ADT is associated with impairment in multiple cognitive domains. Finally, the available literature is reviewed on interventions to mitigate the psychological effects of ADT. Across the array of adverse effects, physical exercise appears to have the greatest potential to address the psychological effects of ADT both in men who are receiving ADT and in their partners.

Many therapies for erectile dysfunction (ED) after prostate cancer treatment improve erectile firmness, yet, most couples stop using aids within 1-2 years. Patients and partners who expect immediate and complete success with their first ED treatment can be demoralized when they experience treatment failure, which contributes to reticence to explore other ED aids. Comprehensive patient education should improve sustainability and satisfaction with ED treatments. Pre-emptive and realistic information should be provided to couples about the probability of recovering natural erections. Beginning intervention early and using a couple-based approach is ideal. Recommendations are provided about the timing of ED treatment, the order of aid introduction, and combination therapies. Renegotiation of sexual activity is an essential part of sexual adaptation. From the outset of therapy, couples should be encouraged to broaden their sexual repertoire, incorporate erection-independent sexual activities, and continue to be sexual despite ED and reduced libido.
